NPDES‐Permitted Facilities A total of 43 National Pollutant Discharge Elimination System (NPDES)-permitted facilities discharge sanitary wastewater, industrial process water or industrial storm water into the study area. All tributaries in the study area are located within the 04100012 HUC and within portions of Huron, Erie, Crawford, Sandusky and Richland counties. Per sampling and monitoring conditions specified in their NPDES permit, each facility must monitor their discharges and report results to Ohio EPA in a discharge monitoring report (DMR). Individual NPDES permits in the Huron River basin watersheds are listed in Table 1. The city of Willard WPCF, city of Norwalk WWTP and Huron Basin WWTP are considered major dischargers based on the volume (>1 MGD) and type of waste they discharge. All other individual NPDES- permitted facilities in the watershed are considered minor dischargers. Minor dischargers include 25 package plants, two trickling filter treatment plants, one sequencing batch reactor, one oxidation ditch and 11 industrial discharges. There are no permitted concentrated animal feeding operations in the watershed. General NPDES permits are a potential alternative for facilities that have a minimal effect on the environment, have similar operations and meet certain eligibility criteria. There are several different types of general permits, including, but not limited to, small sanitary sewer discharges, petroleum bulk storage and non-contact cooling water. A list of facilities covered under each type may be found at epa.ohio.gov/dsw/permits/NonStormgplist.aspx. There are also several types of general permits specific to storm water, including, but not limited to, small MS4s, construction sites, industries and marinas. A list of facilities covered under each type may be found at epa.ohio.gov/dsw/permits/gplist.aspx.

All major dischargers and relevant minor dischargers located in the study area are discussed in detail below. City of Willard WPCP (Ohio EPA Permit # 2PD00005) The City of Willard Water Pollution Control Plant (WPCP) serves approximately 6,290 residents in the city of Willard and unincorporated users. Sewer services for the city are provided by a municipal sanitary sewage treatment plant with an average daily design flow of 4.5 MGD. Sanitary waste from the village receives treatment through influent screw pumps, mechanical bar screening, grease removal, grit removal, activated sludge aeration using four Figure 1 — Annual total phosphorus loadings from the Willard WPCP, 2007‐2016. vertical loop reactors, biological phosphorus removal, secondary clarification (three final clarifiers), ultraviolet disinfection and post aeration. The final treated effluent is discharged to the West Branch Jacobs Creek at RM 0.08. The collection system consists of 40 percent separate and 60 percent combined sewers. A retention lagoon with surface aerators is available to receive wet weather flows from the interceptor sewer serving the Figure 2 — Annual nitrate‐nitrite loadings from the Willard WPCP, combined sewer areas prior to 2007‐2016. entering the treatment plant headworks. The lagoon has two overflow points (Outfall 007 and 009) that activate when the lagoon is filled. In 1999, biofilter cartridges were added to outfalls 007 and 009 to provide more treatment prior to discharge. For any event greater than 7.2 MGD, the excess flow goes to the retention lagoon that has up to 22.5 MGD of storage capacity. Willard WPCP has a retention lagoon to store overflow from the combined collection system. There are three CSO monitoring points at the retention lagoon. Outfall 009 is the northwest overflow,

Outfall 007 is the northeast overflow and Outfall 008 is a drain valve that has been manually closed for years. No overflow occurrences were documented in 2016. Estimated inflow and infiltration (I/I) rate to the system is 2.12 MGD. The city of Willard has an approved pretreatment program. The city has one categorical user that discharges 0.097 MGD of flow, one non-categorical user that discharges 0.01 MGD of flow and four significant non-categorical users that discharge 0.063 MGD of flow. Ohio EPA most recently conducted a compliance sampling inspection and bioassay at the Willard WPCP on Oct. 21 – 22, 2013. The effluent from Outfall 001 was not acutely toxic to Pimephales promelas or Ceriodaphnia dubia. Compliance history for the plant during the sampling period showed no violations during that period. Pollutant loadings from the city of Willard WPCP from 2007 through 2016 were evaluated and annual statistics for total phosphorus and nitrate-nitrite are depicted in Figure 1 and Figure 2. The plant discharged at a fairly consistent flow during the evaluation period with peaks during wet years that demonstrate the large quantity of I/I to the system. The observed phosphorus loads demonstrate a slightly increasing trend over the past 10 years. The annual nitrate-nitrite median loadings have remained steady while the 95th percentile loadings show an increasing trend. Annual discharge concentrations of nitrate-nitrite are high and likely contribute to the elevated levels of nitrate-nitrite observed in Jacobs Creek. The sampling location downstream of the WPCP on Jacobs Creek exceeded the benchmark geometric means for nitrate-nitrite and total phosphorus.

City of Norwalk WWTP (Ohio EPA Permit # 2PD00024) The city of Norwalk WWTP serves approximately 16,600 residents. Sewer services for the city are provided by a municipal sanitary sewage treatment plant with an average daily design flow of 3.5 MGD. The municipal wastewater treatment plant consists of screening, grit removal, flow equalization primary settling, trickling filter, phosphorus removal by chemical addition, final clarification, ammonia stripping, sand filtration, chlorination and de- Figure 3 — Annual total phosphorus loadings for the Norwalk WWTP, 2007‐2016. chlorination. Effluent discharges to the West Branch Rattlesnake Creek at RM 2.34. The sanitary sewer collection system for the city is made up of 80 percent separate sanitary sewers. The city has an approved long-term control plan with final separation to be completed no later than July 31, 2025. The facility had a total phosphorus permit limit violation during April 2016, but it was not necessary to issue a notice of violation. Figure 4 — Annual nitrate‐nitrite loadings from the Norwalk WWTP, Norwalk implements an Ohio 2007‐2016. EPA-approved industrial pretreatment program. Based on this program, Norwalk has seven industrial users, four categorical industrial users and three significant noncategorical industrial users (17 percent of annual flow to the plant). Ohio EPA most recently conducted a compliance sampling inspection and bioassay at the Norwalk WWTP on April 14 – 15, 2014. The effluent from Outfall 001 was not acutely toxic to Pimephales promelas or Ceriodaphnia dubia. Pollutant loadings from the city of Norwalk WWTP from 2007 through 2016 were evaluated and annual statistics for total phosphorus and nitrate-nitrite loadings are displayed in Figure 3 and Figure 4. The plant discharge has fluctuated with wet weather flows. The annual total phosphorus

and median nitrate-nitrite loadings show an overall decreasing trend during the 10-year period observed while the 95th percentile loading of nitrate-nitrite has remained steady. The geometric mean concentration of nitrate-nitrite downstream of the plant in the West Branch of Rattlesnake Creek exceeded the benchmark at 16.17 mg/l. The sampling results in Rattlesnake Creek downstream of the confluence with the West Branch of Rattlesnake Creek are still elevated above the benchmark. Huron Basin WWTP (Ohio EPA Permit # 2PC00001) The Huron Basin WWTP serves approximately 5,000 residents. Sewer services for the village are provided by a municipal sanitary sewage treatment plant with an average daily design flow of 2.0 MGD and a peak hydraulic capacity of 5.5 MGD. The municipal wastewater treatment plant consists of screening, grit removal, comminution, pre- aeration, primary sedimentation, alum addition, rotating biological contactors, secondary clarification, chlorination and de- Figure 5 — Annual total phosphorus loadings for the Huron Basin chlorination. Effluent discharges WWTP, 2007‐2016. to the Huron River at RM 0.81. The sanitary sewer collection system for the village is made up of 100 percent separated sanitary sewers. The I/I rate for the collection system is estimated to be 0.1 MGD. The facility utilizes cured-in-place lining of sanitary main lines in areas of known infiltration. The Huron Basin WWTP had a permit limit violation for low-level mercury in August 2016, but it was not necessary to issue a notice of violation. The Huron Basin Figure 6 — Annual nitrate‐nitrite loadings for the Huron Basin WWTP from 2007‐2016. WWTP does not have an approved pretreatment program. Two categorical industrial users in the service area are monitored under indirect discharge permits to ensure that surfactants used in their process do not cause foaming issues at the WWTP.

Ohio EPA most recently conducted a compliance sampling inspection and bioassay at the Huron Basin WWTP on Oct. 28 – 29, 2013. The effluent from Outfall 001 was not acutely toxic to Pimephales promelas or Ceriodaphnia dubia. Pollutant loadings from the Huron Basin WWTP between 2007 and 2016 were evaluated and annual statistics for total phosphorus and nitrate-nitrite loadings are displayed in Figure 5 and Figure 6. Phosphorus loads show a decreasing trend. The annual median nitrate-nitrite loadings have remained steady over the 10-year period with a decreasing trend in the 95th percentile loadings. Plymouth WWTP (Ohio EPA Permit # 2PB00014) The Plymouth WWTP serves approximately 1,857 residents. Sewer services for the village are provided by a municipal sanitary sewage treatment plant with an average daily design flow of 0.45 MGD. The municipal wastewater treatment plant consists of a sequencing batch reactor plant. Effluent discharges to the West Branch Huron River at RM 38.9. The sanitary sewer collection system for the village is made up of 100 percent separated sanitary sewers. The current average I/I Figure 7 — Annual total phosphorus loadings for the Plymouth WWTP, 2007‐2016. rate for the collection system is estimated to be 0.05 MGD. The Plymouth WWTP had a permit frequency violation for neglecting to collect the April 2016 sample for total phosphorus. There are no industrial users in the service area. Total phosphorus pollutant loadings from the Plymouth WWTP between 2007 and 2016 were evaluated and the annual statistics are displayed in Figure 7. Phosphorus loads show a decreasing trend. The geometric mean concentration for total phosphorus downstream of the plant exceeds the benchmark of 0.1 mg/l at 0.2 mg/l (geometric mean upstream of the plant was 0.1 mg/l). There is no monitoring requirement for nitrate-nitrite in the facility permit, however, the nitrate-nitrite geometric mean slightly exceeds the benchmark downstream of the plant.

Shiloh WWTP (Ohio EPA Permit # 2PB00017) The Shiloh WWTP serves approximately 637 residents. Sewer services for the village are provided by a municipal sanitary sewage treatment plant with an average daily design flow of 0.12 MGD. The municipal wastewater treatment plant consists of screening, trickling filter, biological nitrification, clarification and UV. Effluent discharges to an unnamed tributary (48.05) to West Branch Huron River (Hale’s Ditch) at RM 3.5. Figure 8 — Annual total phosphorus loadings for the Shiloh WWTP, 2007‐2016. The sanitary sewer collection system for the village is made up of 100 percent separated sanitary sewers. The current average I/I rate for the collection system is estimated to be 0.04 MGD. The plant receives approximately 0.001 MGD of waste from two industrial users. The Shiloh WWTP had a permit limit violation for CBOD5 in February and March 2016, ammonia in February, June and July 2016, low-level mercury in April and June 2016 and E. coli in June, August, September and October 2016. Findings and Orders were issued to Shiloh on May 23, 2016 to address compliance issues and a plan to build a new plant was submitted. Total phosphorus pollutant loadings from the Shiloh WWTP between 2007 and 2016 were evaluated and the annual statistics are displayed in Figure 8. Median phosphorus loads show an increasing trend. There is no monitoring requirement for nitrate-nitrite in the facility permit. The total phosphorus and nitrate-nitrite geometric means exceed the benchmarks downstream of the plant. In addition, four chloride exceedances were observed in the stream downstream of the WWTP. The Shiloh Water Treatment Plant backwashes an ion exchange softener with brine water approximately daily and discharges to the WWTP. This additional input of sodium chloride to the plant with existing chloride levels in the WWTP (no monitoring requirement in the existing permit) potentially contribute to the exceedance of chloride in the stream.

Lake Sampling Inland Lakes Monitoring Ohio EPA has implemented a sampling strategy that focuses on evaluating chemical conditions near the surface and physical conditions in the water column of inland lakes. Physical profile measurements are summarized either for the entire water column or the epilimnion depending on the existence of thermal stratification. The sampling target consists of an even distribution of 5 sampling events over a one-year period and collected during the recreation season of May 1 through October 31. Key parameters analyzed in lakes include chlorophyll-a, ammonia, D.O., pH, total dissolved solids along with various metals for multiple beneficial use assessments. Other parameters used to evaluate lakes include secchi depth, total phosphorus and total nitrogen. Details of the sampling protocol used at the time of this sampling are outlined in the 2016 Inland lakes sampling Procedures Manual. Sampling objectives for inland lake surveys are defined in Ohio EPA’s Inland Lakes Sampling QAPP, and the rules relative to inland lakes beneficial uses are described in the 2010 and successive Water Quality Monitoring Integrated Reports. Study Lake: Norwalk Reservoir #3 (Memorial Reservoir) Norwalk Reservoir #3 (Memorial Reservoir), located in Huron County within the Huron Erie Lake Plain ecoregion, was constructed in 1954 and is one of three manmade lakes built to store drinking water for the city of Norwalk. The three reservoirs combined cover 159 acres and hold 700 million gallons of water. Primary water source is rainwater runoff from an eight square mile area east of the city. Water flows from Norwalk Reservoir #2 into Norwalk Memorial, which covers approximately 93 acres and has 2.4 miles of shoreline with a maximum depth of around 30 feet (Table 1). The city of Norwalk Reservoir complex is in Huron County on approximately 320 acres of land located on Old State Road, south of St. Rte. 18. The park includes playgrounds, shelter houses, walking trails, frisbee golf and boat launch Figure 1. Location of Memorial Reservoir. ramps. Fishing and boating (electric motors only) are permitted. Swimming is not allowed.

Key Attributes of Memorial Reservoir Ecoregion: Huron Erie Lake Plain (HELP) Surface Area: 93 acres Residents Served: 16,200 Storage Capacity: 350 million gallons Watershed: 87.8 square miles Drinking WaterProtection Area 8 square miles Maximum Depth: 9.2 meters (30 ft.)

Physical Attributes Memorial reservoir is irregularly shaped, generally fetching from the southwest to the northeast. The Reservoir is an upground reservoir and is one of three reservoirs utilized as a public drinking water source for the city of Norwalk. However, the reservoir is a “hybrid” upground reservoir since it receives water directly from a tributary (Little Raccoon Cr.). Thus, water quality in Memorial Reservoir is directly impacted by watershed activities as compared to typical upground reservoirs. True upground reservoirs involve controlled pumping of source water from a nearby stream or in some cases from groundwater. Despite the fact that upground reservoirs in northwestern Ohio are prone to steady wind action, the depth of Memorial Reservoir allows for lake stratification to occur. The north end of the lake consists mostly of a shallow flat. The rest of the lake slopes fairly quickly toward the deepest point (9 m), about mid lake on the west side of the reservoir. The L1 sampling location on Memorial Reservoir is approximately mid-lake close to the west bank, near GPS location 41.2344 latitude -82.5903 longitude (figure 2). The “L1” naming convention indicates a primary sampling location that is deemed representative of the whole lake and is the location used to determine attainment status of applicable beneficial uses. Other locations (e.g. L2, L3 etc.) may be determined necessary to support attainment decisions on larger lakes and reservoirs.

Watershed Overview Norwalk Memorial Reservoir Lies within the Huron Eriw Lake POlains (HELP) ecoregion. The surface geology in the watershed largely consists of Devonian Ohio shale, Berea sandstone, Bedford shale, and Maxville Limestone with minor influence from other shales and limestone deposits. Most of the land in Huron county is in agriculture, consisting primarily of the three main cash crops: corn, wheat and soybeans. Huron County is one of the top counties in the state in terms of total farm income. Several cities and villages in the County are located along major highway corridors. Scattered residential and some commercial development occurs along highway corridors between cities and villages while agriculture is the major land use in the outlying areas. Huron County consists of 317,614 acres. As of the last assessment in 2014, the vast majority of acres (71%) are used for cropland. Approximately 4% of land use is urbanized or used for residential, commercial and industrial development. There is also a significant amount of acreage that is considered “open space” which includes forested land, shrub or scrub areas, open water, and wooded and non- forested wetlands (Huron County). A breakdown of this acreage by various land use categories is provided in table 2:

Table 2. Huron County Land Cover Type of Cover Acres (Percent) Total 317,614.5 (100.0%) Cropland 224,965.99 (70.83%) Forest 51,898.13 (16.34%) Pasture 25,694.97 (8.09%) Urban (open, impervious surfaces) 12,228.14 (3.85%) Open Water 2,382.11 (0.75%) Wetlands (Wooded/Herbaceous) 444.66 (0.14%) Source: ODOD, Office of Research Results Discussion Water Column Chemistry A physical profile of the water column was evaluated during each sampling event in 2016 and 2017 at the L1 sampling location at Memorial Reservoir. Readings were recorded at the surface (which is defined as a 0.5-meter depth), at 0.5-meter intervals thereafter, with a final measurement collected at 0.5 meters above the bottom of the lake. In addition, environmental samples were collected to determine exceedances of existing EHW Aquatic Life Use (ALU) criteria and to assess the trophic dynamics and water quality status of Memorial Reservoir during the 2016-17 sample seasons. Base aquatic life parameters that were evaluated to assess the current ALU include dissolved solids, arsenic, cadmium, chromium, copper, lead, nickel, selenium and zinc. Individual sample concentrations are first compared to Outside Mixing Zone Average (OMZA) numeric criteria. If the OMZA is exceeded in more than 10 percent of the total samples tested for any parameter, the use is considered non-support. Physical conditions changed throughout the sampling season in this relatively deep reservoir. Stratification occurred early in the sampling season and ended in late summer. Thermal stratification occurs in deep lakes during the warm summer months, consisting of an upper mixed zone (epilimnion), a slightly denser middle zone (metalimnion), and a lower zone (hypolimnion) where mixing is impeded by a density barrier caused by lower water temperatures near the bottom of a lake. A sharp decrease in temperature and dissolved oxygen is often noted where the hypolimnion forms. With the exception of one sample in May 2017 (16.2 mg/L), surface water D.O. did not fluctuate significantly, ranging between 5.0 and 9.0 mg/L. Only one pH reading was observed greater than 9.0 SU. Neither D.O., pH nor metals were found in exceedance of their EWH criteria.

Useful information was obtained from samples collected near the bottom. The hypolimnion can become depleted of oxygen if consumption by decomposing organic matter exceeds reaeration by atmospheric diffusion and photosynthesis. Fish access to habitat, cool water and benthic prey can be limited if conditions become hypoxic (D.O. < 2 mg/L). Hypoxia conditions were documented during numerous sampling events. Hypoxia was documented at depths of two to four meters. Chemistry data from samples collected 0.5 m from the bottom did not indicate that significant amounts of phosphorus bound to sediment particles were being released to the water column due to redox reactions that break the bond between phosphate molecules and calcium and iron. Mean total phosphorus concentration at the surface for the 10 sampling events was 30 ppb compared to a mean bottom concentration of 22.7 ug/L. This information indicates that internal loading of phosphorus is not a likely source of nutrients triggering algal blooms in Memorial Reservoir.

Sediment Chemistry A surface sediment sample was collected in October 2016 and analyzed for metals, nutrients, s- VOCs (PAHs), PCBs and pesticides (organo-chlorine insecticides). Most compounds tested were either not detected or were well below benchmark guidelines used by Ohio EPA to evaluate sediment data. Phytoplankton Assessment The phytoplankton community in Norwalk Memorial Reservoir was characterized based on raw water samples collected using a tube sampler. Samples were collected during the May, July and September sampling events, fixed with Lugol’s and submitted to BSA Environmental Services, Inc. for analysis. The phytoplankton present in a representative aliquot were identified to at least genus level (usually species), and cell densities (cells/L) and bio-volumes (µm3/L) were estimated in accordance with Standard Methods for the Examination of Water and Wastewater Method No. 10200 (Rice, Baird, & Eaton, 2017). Phytoplankton communities typically exhibit a seasonal succession when factors like water temperature, nutrients, transparency and photoperiod favor certain types. Grazing by larval fish and zooplankton also has an effect. Temperate lakes in Ohio are usually dominated by diatoms in the spring until micronutrients like silica are depleted and blue-green algae in the fall when an ability to control buoyancy and fix nitrogen from the atmosphere gives certain types a competitive edge. The following graphs summarize total bio-volume by algal class in Norwalk Memorial Reservoir. In general, the population seems diverse and balanced, with eight different classes of algae represented. Temporal variability exhibited a normal succession for the most part. This can be greatly affected by springtime extremes in temperature and rainfall on either end of the spectrum.

Beneficial Use Assessment Public Drinking Water Use Public drinking water use attainment status will be determined and reported in the 2018 Integrated Report. Ohio EPA is in the process of preparing the report, which fulfills the State’s reporting obligations under Section 305(b) (33 U.S.C. 1315) and Section 303(d) (33 U.S.C. 1313) of the Federal Clean Water Act. Like all public lakes in Ohio (except Piedmont Reservoir), Norwalk Memorial Reservoir is designated a public water supply (PWS) in the Ohio WQS. The reservoir is also currently used as a Public Drinking Water Supply (PDWS) source water for the City of Norwalk and some surrounding suburbs serving approximately 16,000 residents. In Ohio, PDWS source water quality is assessed by comparing water quality data within an assessment unit (AU) to established numeric criteria for the core indicators: nitrate; pesticides and other contaminants; algae/cyanotoxins; and Cryptosporidium (Ohio EPA D. , 2018). A PDWS is deemed impaired for its use if there are two or more excursions of nitrate above 10.0 mg/L within a 5-year period. The AU is placed on a watch list if there is one nitrate value that exceeds 8 mg/L. Memorial Reservoir was sampled 5 times each during 2016 and 2017 for nitrates. Results for nitrate were well below 8 mg/L for all ten sampling events at Memorial Reservoir in 2016-2017. The atrazine (pesticide) indicator is based on a maximum contaminant level (MCL) of 3.0 µg/L (developed under the Safe Drinking Water Act). Results for atrazine were below the MCL for all ten sampling events at Memorial Reservoir during the 2016-17 sampling seasons. Expanded organics sampling was also conducted on October 19, 2016 to screen for organic constituents in the water column and sediments. Except for a bis(2-Ethylhexyl) phthalate concentration of 3.06 mg/kg in the sediment, all other organic parameters were below their associated detection limit. Bis(2-Ethylhexyl) phthalate is a plasticizer used in the production of Polyvinyl chloride (PVC) and exhibits low toxicity from acute and chronic exposures (USEPA 117- 81-7 Hazard Summary). An AU is considered impaired if a source water has two or more excursions above state drinking water thresholds for cyanotoxins within a 5-year period. It is placed on a watch list if there is a cyanotoxin concentration that is greater than or equal to 50% of the state drinking water thresholds. Cyanotoxin samples (microcystin, saxitoxin and cylindrospermopsin) were collected and analyzed five times at L1 during the assessment period at Memorial Reservoir. All but two cyanotoxin results were below detection. One sample result for saxitoxins (0.27 ug/L) exceeded the threshold of 0.2 ug/L for a public drinking water supply and supported the watch list designation for algae/cyanotoxins. The AU including Memorial Reservoir (Norwalk Creek – 04100012 06 03) is currently listed as impaired for algae/cyanotoxins based on microcystin detections in Memorial Reservoir during 2014 and 2015 (see Ohio EPA’s 2018 Integrated Water Quality Monitoring and Assessment Report). Recreation Use Assessment Ohio conducts a monitoring and notification program of selected public and semi-private beaches to test the water quality and notify the public whenever bacteria and cyanotoxin levels present a potential health risk to those engaged in water activities. In support of this monitoring program, bacteria and cyanotoxin concentrations are often examined to determine suitability for Primary Contact Recreation (PCR) use. Bacteria samples were not collected as part of this survey

The State of Ohio has established recommended cyanotoxin threshold concentrations for recreational advisories. For public beaches, a Recreational Public Health Advisory is posted when a possible harmful algal bloom (HAB) is visually confirmed and/or when cyanotoxin levels are equal to or exceed Recreational Public Health Advisory thresholds, whether or not a HAB is still present. An Elevated Recreational Public Health Advisory (no contact) is posted when cyanotoxin levels are equal to or exceed the elevated recreational public health advisory thresholds (State of Ohio, 2016). Beach advisories can be found at: http://publicapps.odh.ohio.gov/beachguardpublic/ . Samples tested for a suite of cyanotoxins (microcystins, cylindrospermopsin and saxitoxin) were also submitted for phytoplankton identification and quantification during all sampling events. The cyanotoxin samples were all below recreational thresholds, and all samples were below detection levels for microcystins and cylindrospermopsin. However, the phytoplankton enumeration samples found some genera with the ability to produce cyanotoxins. Human Health - Fish Consumption Ohio has been sampling streams and lakes annually for sport fish contamination since 1993. Fish are analyzed for contaminants that bioaccumulate in fish and that could pose a threat to human health if consumed in excessive amounts. Contaminants analyzed in Ohio sport fish include mercury, PCBs, DDT, mirex, hexachlorobenzene, lead, selenium and several other metals and pesticides. Other contaminants are sometimes analyzed if indicated by site-specific current or historic sources. No consumption advisories have been issued beyond the statewide advisory for mercury in Memorial Reservoir. Aquatic Life Use Assessment The current aquatic life use (ALU) designation for all inland lakes in Ohio is exceptional warmwater habitat (EWH) except for upground reservoirs which are designated warmwater habitat (WWH). In order to evaluate the ALU in Memorial Reservoir, ammonia, dissolved oxygen, pH, total dissolved solids and various metals were analyzed. Statewide water quality criteria for these parameters are summarized in Table 35-1 of the Ohio water quality standards. Other important parameters for assessing lake condition in Memorial Reservoir included nutrient parameters (e.g. total phosphorus, total nitrogen) and biological response variables (e.g. chlorophyll-a). Where criteria do not exist, a common approach to assessing relative lake condition is to compare lake water quality sampling data to a regional and lake-type derived percentiles (e.g. 25th) of existing lake data. The lower 25th percentile generally represents minimally impacted conditions protective of designated uses. For Ohio EPA, inland lake ALU benchmarks were calculated for total nitrogen (T-N), total phosphorus (T-P) and chlorophyll-a (Chl. a) based on the lower 25th percentile of lake median data and for secchi depth based on the upper 75th percentile of lake median data. Data used to determine benchmarks were collected by Ohio EPA from Ohio inland lakes between 1989 and 2006.

Chlorophyll-a, total phosphorus, total nitrogen and Secchi depth are evaluated by first calculating a median value from the two-year dataset. This value is then compared to the ALU targets identified in table 3. Dissolved oxygen, pH and ammonia were evaluated in a manner similar to base aquatic life parameters. Average D.O. and median pH values were calculated from profile readings taken in the epilimnion since the lake does stratify.

Memorial Reservoir revealed signs of enrichment in the source water since the two response variables, Chlorophyll a and Secchi exceeded their targets, and the two causal nutrient parameters, total nitrogen and total phosphorus were well above their respective benchmarks. Due to its hybrid nature, Memorial Reservoir is prone to external sources of nutrients that can be attributed to Norwalk Creek, an agricultural impacted stream that feeds into the reservoir from the East. Trend Assessment Many inland lakes in Ohio were assessed in May and August 1978 and April and August 1990 as a part of a Section 314 Clean Lakes Assessment Grant. This data was summarized in the 1982 305(b) Report and eventually integrated into Volume 3 of the 1996 Ohio Water Resource Inventory 305(b) Report, which can be found at epa.ohio.gov/portals/35/documents/96vol3.pdf (Ohio EPA, 1996). The report describes trophic state index (TSI) as one of several metrics used to assess the condition of Ohio’s public lakes. Carlson’s TSI is a numerical representation of a lake’s state of productivity along a scale of 0 to 100. Each major division (10, 20, 30, etc.) represents a doubling in algal biomass based on transparency, total phosphorus and chlorophyll-a measurements (Carlson, 1977). Unproductive, oligotrophic lakes score on the lower end of the scale, mesotrophic lakes are in the middle and eutrophic/hyper-eutrophic lakes occupy the upper end of the continuum. The Carlson TSI values were calculated in the same manner as in the 1990 Ohio 305(b) Lakes Report, using formulas from Reckhow and Chapra (Reckhow & Chapra, 1983) as follows: • Secchi disk TSI = 60 - 14.41 ln (SD meters) • Chlorophyll-a TSI = 9.81 ln (Chl-a ug/l) + 30.6 • Total phosphorus TSI = 14.42 ln (TP ug/l) + 4.15

A TSI value was calculated for each of the three variables collected from Memorial Reservoir in 2016 (Table 4). Per Carlson’s (1977) recommendation, average summer (July, August, September) chlorophyll-a and spring (April, May, June) total phosphorus TSI values were used to determine the final TSI value. Transparency based (Secchi depth) TSI values were calculated but Carlson warns against using transparency as a variable in waters with high non-algal turbidity, namely, sediment and silt (Carlson, 1980). Such is the case with many lakes and more specifically, reservoirs in Ohio. Trophic State Index ranges based on Carlson’s classification system are as follows: Oligotrophic (lacking nutrients): Less than 38 TSI Mesotrophic (midrange nutrient availability): 38-47 TSI Eutrophic (nutrient enriched): 48-66 TSI Hypereutrophic (over Enriched): >66 TSI Since Ohio does not have a very robust baseline of lake data, the use of TSI as a general tool for trend assessment is appropriate. Based on data collected in 2016, the final TSI for Memorial Reservoir was calculated to be 58.4. This score indicates the lake is productive and reflects a eutrophic status. However, Memorial Reservoir was not sampled by the Ohio EPA before 2016, so a trend assessment could not be determined based solely on the 2016/17 data collection. While nutrient availability in sediment and biomass is not considered, the TSI value shows there are enough nutrients (TP) present in the water column to cause this lake to be considered nutrient enriched, since all but two of the TSI-TP values were above the eutrophic/nutrient-enriched threshold of 48. Conclusion Upground Reservoirs are a reliable way for communities to store surface water prior to its treatment for drinking. Since they are off stream, they have an advantage over traditional impoundments because the quality of inlet water pumped can be somewhat controlled. This is especially true if the source water has seasonally high nitrate levels. These reservoirs are also designed with enough storage capacity to withstand periods of drought. Many upground reservoirs have boat ramps and are stocked with sportfish. While this provides an important source of recreation, all lake management decisions should be made based on drinking water as the primary use.

Norwalk Memorial Reservoir is a hybrid lake in that it is an instream impoundment with upground construction. This makes it more susceptible to nutrient enrichment from Norwalk Creek and the surrounding watershed. It has also been in service for over 60 years, which is enough time for nutrients to accumulate in the system. This is reflected in nutrient and chlorophyll a concentrations above their relative benchmarks.

Study Lake - Willard Reservoir Willard Reservoir is a public drinking water source in the southwestern corner of Huron County on St. Rte. 61, two miles north of New Haven, in New Haven Township. Construction of the upground reservoir was completed in 1971. The reservoir covers 215 acres and holds 2.3 billion gallons of water. Source water is pumped from the West Branch Huron River (RM 33.80) into Willard Reservoir strategically to avoid high nutrient concentrations. Willard Reservoir provides initial treatment for the water system that supplies drinking water to approximately 9,255 area residents of Willard, Celeryville, New Haven, the Village of Plymouth and to rural area customers. Willard Reservoir has a concrete launch ramp. Boating is restricted to hand or electric power only and swimming is Figure 5. Location of Willard Reservoir. prohibited. However, ample recreational opportunities are provided in and around the reservoir including but not limited to: Fishing, boating/kayaking, waterfowl hunting, and walking via a 2.3-mile walking/biking trail. Table 5. Key Attributes of Willard Reservoir Ecoregion: Huron Erie Lake Plain (HELP) Surface Area: 215 acres Residents Served: 7,600 Storage Capacity: 2.3 Billion gallons Watershed: 87.8 square miles Drinking WaterProtection Area 8 square miles Maximum Depth: 13.7 meters (45 ft.) Shoreline: 2.3 miles Ecoregion: Eastern Cornbelt Plains

Physical Attributes The L1 sampling location on Willard Reservoir is approximately mid-lake, centered at GPS location 41.0625 latitude -82.6631 longitude (figure 2). The “L1” naming convention indicates a primary sampling location that is deemed representative of the whole lake and is the location used to determine attainment status of applicable beneficial uses. Other locations (e.g. L2, L3 etc.) may be determined necessary to support attainment decisions on larger lakes and reservoirs. Willard reservoir is polygon shaped generally fetching from the southwest to the northeast. Being a true upground reservoir, the city of Willard can somewhat control the amount of nutrients entering the reservoir by choosing the best conditions to draw water from West Branch of the Huron River. Despite the fact that upground reservoirs in northwestern Ohio are prone to steady wind action, the depth of Willard Reservoir allows for lake stratification to occur. The Willard Reservoir Shoreline drops off rather quickly into deeper water throughout. There is variable bottom structure with submerged humps and islands, mostly on the southwest side of the lake near the boat ramp. The deepest part of the lake is about mid lake on the east side of the reservoir.

Watershed Overview The reservoir was built in the Eastern Corn Belt Plains (ECBP) ecoregion over a surface geology consisting mainly of Devonian Berea Sandstone and Bedford Shale along with Ohio Shale. Most of the land in Huron county is in agriculture, consisting primarily of the three main cash crops: corn, wheat and soybeans. The landscape surrounding Willard Reservoir is typical of Huron County’s land use. Huron County is one of the top counties in the state in terms of total farm income. Several cities and villages in the County are located along major highway corridors, with the city of Willard located about 3 miles west of the reservoir. Huron County consists of 317,614 acres. As of the last assessment in 2014, the vast majority of acres (71%) are used for cropland. Approximately 4% of land use is urbanized or used for residential, commercial and industrial development. There is also a significantly large amount of acreage that is considered “open space” which includes forested land, shrub or scrub areas, open water, and wooded and non-forested wetlands (Huron County). A breakdown of this acreage by various land use categories is provided in table 6: Table 6. Huron County Land Cover Type of Cover Acres (Percent) Total 317,614.5 (100.0%) Cropland 224,965.99 (70.83%) Forest 51,898.13 (16.34%) Pasture 25,694.97 (8.09%) Urban (open, impervious surfaces) 12,228.14 (3.85%) Open Water 2,382.11 (0.75%) Wetlands (Wooded/Herbaceous) 444.66 (0.14%) Source: ODOD, Office of Research Results Discussion Water Column Chemistry A physical profile of the water column was evaluated during each sampling event in 2016 and 2017 at the L1 sampling location at Willard Reservoir. Readings were recorded at the surface (which is defined as a 0.5-meter depth), at 0.5-meter intervals thereafter, with a final measurement collected at 0.5 meters above the bottom of the lake. In addition, environmental samples were collected to determine exceedances of existing EHW Aquatic Life Use (ALU) criteria and to assess the trophic dynamics and water quality status of Willard Reservoir during the 2016-17 sample seasons. Base aquatic life parameters that were evaluated to assess the existing ALU include dissolved solids, arsenic, cadmium, chromium, copper, lead, nickel, selenium and zinc. Individual sample concentrations are first compared to Outside Mixing Zone Average (OMZA) numeric criteria. If the OMZA is exceeded in more than 10 percent of the total samples tested for any of these parameters, the use is considered in non-attainment. Physical conditions changed throughout the sampling season in this relatively deep reservoir. Stratification occurred early in the sampling season and ended in late summer. Thermal stratification occurs in deep lakes during the warm summer months, consisting of an upper mixed zone (epilimnion), a slightly denser middle zone (metalimnion), and a lower zone (hypolimnion) where mixing is impeded by a density barrier caused by lower water temperatures near the bottom of a lake. A sharp decrease in temperature and dissolved oxygen is often noted where the hypolimnion forms. Surface water D.O. did not fluctuate significantly, ranging between 8.4 and 10.6 mg/L. No pH readings exceeded 9.0 SU, and daytime pH was quite consistent ranging between 8.2 and 8.5. Neither D.O., pH nor metals were found in exceedance of their EWH criteria. Useful information was obtained from samples collected near the bottom. The hypolimnion can become depleted of oxygen if consumption by decomposing organic matter exceeds reaeration by atmospheric diffusion and photosynthesis. Fish access to habitat, cool water and benthic prey can be limited if conditions become hypoxic (D.O. < 2 mg/L). Hypoxia conditions were documented during numerous sampling events. Hypoxia was documented at depths up to four meters. Chemistry data from samples collected 0.5 m from the bottom did not indicate that significant amounts of phosphorus bound to sediment particles is being released to the water column due to redox reactions that break the bond between phosphate molecules and calcium and iron. Mean total phosphorus concentration at the surface for the 10 sampling events was 30 ppb compared to a mean bottom concentration of 22.7 ug/L. This information indicates that internal loading of phosphorus is not a likely source of nutrients triggering algal blooms in Willard Reservoir.

Sediment Chemistry A surface sediment sample was collected in October 2016 and analyzed for metals, nutrients, s- VOCs (PAHs), PCBs and pesticides (organo-chlorine insecticides). Most compounds tested were either not detected or were well below guidelines used by Ohio EPA to evaluate data. Phytoplankton Assessment

The phytoplankton community in Willard Reservoir was characterized based on raw water samples collected using a tube sampler. Samples were collected during the May, July and September sampling events, fixed with Lugol’s and submitted to BSA Environmental Services, Inc. for analysis. The phytoplankton present in a representative aliquot were identified to at least genus level (usually species), and cell densities (cells/L) and bio-volumes (µm3/L) were estimated in accordance with Standard Methods for the Examination of Water and Wastewater Method No. 10200 (Rice, Baird, & Eaton, 2017).

Phytoplankton communities typically exhibit a seasonal succession when factors like water temperature, nutrients, transparency and photoperiod favor certain types. Grazing by larval fish and zooplankton also has an effect. Temperate lakes in Ohio are usually dominated by diatoms in the spring until micronutrients like silica are depleted and blue-green algae in the fall when an ability to control buoyancy and fix nitrogen from the atmosphere gives certain types a competitive edge. The phytoplankton communities usually transition to blue green algae (cyanobacteria) in the fall when an ability to control buoyancy and fix nitrogen from the atmosphere gives certain cyanobacteria a competitive edge. Cyanobacteria dominance during the growing season can initiate significant harmful algal blooms in highly productive, nutrient enriched systems.

The following graphs summarize total bio-volume by algal class in Willard Reservoir. In general, the population seems diverse and balanced, with seven different classes of algae represented. Temporal variability exhibited a normal succession for the most part. This can be greatly affected by springtime extremes in temperature and rainfall on either end of the spectrum. To protect public health, Ohio has recreation action levels for the microcystins toxin. A Recreational Public Health advisory is posted by the Health Department at beaches with surface water levels ≥6 ppb and a No Contact advisory is posted at levels ≥ 20 ppb if human or animal illness is also documented. Even though some genera with the ability to produce toxins were documented in the enumeration samples, results for all the toxin samples were below respective reporting limits. This indicates that either no toxins are being produced or that population densities are low, and little is present.

Beneficial Use Assessment Public Drinking Water Use Public drinking water use attainment status will be determined and reported in the 2018 Integrated Report. Ohio EPA is in the process of preparing the report, which fulfills the State’s reporting obligations under Section 305(b) (33 U.S.C. 1315) and Section 303(d) (33 U.S.C. 1313) of the Federal Clean Water Act.

Like all public lakes in Ohio (except Piedmont Reservoir), Willard Reservoir is designated a public water supply (PWS) in the Ohio WQS. The reservoir is also currently used as a Public Drinking Water Supply (PDWS) source water for the City of Willard and some surrounding suburbs, serving approximately 7,600 people. In Ohio, PDWS source water quality is assessed by comparing water quality data within an assessment unit (AU) to established numeric criteria for the core indicators: nitrate; pesticides and other contaminants; algae/cyanotoxins; and Cryptosporidium (Ohio EPA D. , 2018). A PDWS is deemed impaired for its use if there are two or more excursions of nitrate above 10.0 mg/L within a 5-year period. The AU is placed on a watch list if there is one nitrate value that exceeds 8 mg/L. Willard Reservoir was sampled 5 times each during 2016 and 2017 for nitrates. Results for nitrate were well below 8 mg/L for all ten sampling events at during 2016-2017. The atrazine (pesticide) indicator is based on a maximum contaminant level (MCL) of 3.0 µg/L (developed under the Safe Drinking Water Act). Results for atrazine were also below the MCL for all ten sampling events at Willard Reservoir during the 2016-17 sampling seasons. An AU is considered impaired if a source water has two or more excursions above state drinking water thresholds for cyanotoxins within a 5-year period. It is placed on a watch list if there is a cyanotoxin concentration that is greater than or equal to 50% of the state drinking water thresholds. Cyanotoxin samples (microcystin, saxitoxin and cylindrospermopsin) were collected and analyzed five times each at L1 during the 2016/17 sampling effort. All but two cyanotoxin results were below instrument detection. Of the two Microcystin samples that were above detection, one collected in September 2017 exceeded a value above 50% of the threshold. Ohio EPA Division of Drinking and Groundwater (DDAGW) sampling of the raw water revealed microcystin levels above the drinking water threshold once during 2015, and again on numerous occasions during the fall of 2017, placing the AU on the impaired list. Recreation Use Assessment Ohio conducts a monitoring and notification program of selected public and semi-private beaches to test the water quality and notify the public whenever bacteria and algal toxin levels present a potential health risk to those engaged in water activities. In support of this monitoring program, bacteria and algal toxin concentrations are often examined to determine suitability for Primary Contact Recreation (PCR) use. Bacteria samples were not collected as part of this survey since full body contact is not allowed. Standards for algal toxin concentrations are currently being developed, but the State of Ohio has established thresholds for recreational advisories. For public beaches, a recreational public health advisory is posted when a possible harmful algal bloom (HAB) is visually confirmed and/or when cyanotoxin levels are equal to or exceed recreational public health advisory thresholds, whether or not a HAB is still present. An elevated recreational public health advisory (no contact) is posted when cyanotoxin levels are equal to or exceed the elevated recreational public health advisory thresholds (State of Ohio, 2016). Samples tested for a suite of cyanotoxins (microcystins, cylindrospermopsin and saxitoxin) were also submitted during all sampling events. To protect public health, Ohio has drinking and recreation action levels for the microcystins toxin. A Do Not Drink advisory is issued at concentrations in finished water ≥ 1 ppb. A Recreational Public Health advisory is posted at beaches with surface water levels ≥6 ppb and a No Contact advisory is posted at levels ≥ 20 ppb if human or animal illness is also documented. Beach advisories can be found at: http://publicapps.odh.ohio.gov/beachguardpublic/ Even though some genera with the ability to produce toxins were documented in the enumeration samples, results for all of the toxin samples were below respective reporting limits. This indicates that either no toxins are being produced or that population densities are low, and little is present. Human Health - Fish Consumption Ohio has been sampling streams annually for sport fish contamination since 1993. Fish are analyzed for contaminants that bioaccumulate in fish and that could pose a threat to human health if consumed in excessive amounts. Contaminants analyzed in Ohio sport fish include mercury, PCBs, DDT, mirex, hexachlorobenzene, lead, selenium and several other metals and pesticides. Other contaminants are sometimes analyzed if indicated by site-specific current or historic sources. No consumption advisories have been issued beyond the statewide advisory for mercury in Willard Reservoir. Aquatic Life Use Assessment The aquatic life use (ALU) designation for all inland lakes in Ohio is exceptional warmwater habitat (EWH) except for upground reservoirs which are designated warmwater habitat (WWH). In order to evaluate the ALU in Willard Reservoir, ammonia, dissolved oxygen, pH, total dissolved solids and various metals were analyzed. Statewide water quality criteria for these parameters are summarized in Table 35-1 of the Ohio water quality standards. Other important parameters for assessing lake condition in Willard Reservoir included nutrient parameters (e.g. total phosphorus, total nitrogen) and biological response variables (e.g. chlorophyll-a). Where criteria do not exist, a common approach to assessing relative lake condition is to compare lake water quality sampling data to a regional and lake type derived percentile (e.g. 25th) of existing lake data. The lower 25th percentile generally represents minimally impacted conditions protective of designated uses. For Ohio EPA, inland lake ALU benchmarks were calculated for total nitrogen (T-N), total phosphorus (T-P) and chlorophyll-a (Chl. a) based on the lower 25th percentile of lake median data and for secchi depth based on the upper 75th percentile of lake median data. All data used for benchmarks were collected by Ohio EPA from Ohio inland lakes between 1989 and 2006. Chlorophyll-a, total phosphorus, total nitrogen and Secchi depth are evaluated by first calculating a median value from the two-year dataset. This value is then compared to the ALU targets identified in table 35-1. Dissolved oxygen, pH and ammonia were evaluated in a manner similar to base aquatic life parameters. Average D.O. and median pH values were calculated from profile readings taken in the epilimnion since the lake does stratify. Table 7 — Summary of important lake data collected in Willard Reservoir.

D.O. (average) and pH (median) numbers in the table 7 are calculated from profile readings. Only numbers from the epilimnion are used if the lake is stratified such as in this case. Ammonia concentrations and pH are compared to OMZA numeric criteria and for D.O. to OMZM. They are a concern if more than 10% of the values exceed their respective criterion. Other parameters that were evaluated include dissolved solids, arsenic, cadmium, chromium, copper, lead, nickel, selenium and zinc. Individual sample concentrations are compared to OMZA numeric criteria. No exceedances were documented. Trend Assessment Many inland lakes in Ohio were assessed in May and August 1978 and April and August 1990 as a part of a Section 314 Clean Lakes Assessment Grant. This data was summarized in the 1982 305(b) Report and eventually integrated into Volume 3 of the 1996 Ohio Water Resource Inventory 305(b) Report, which can be found at epa.ohio.gov/portals/35/documents/96vol3.pdf (Ohio EPA, 1996). The report describes trophic state index (TSI) as one of several metrics used to assess the condition of Ohio’s public lakes. Carlson’s TSI is a numerical representation of a lake’s state of productivity along a scale of 0 to 100. Each major division (10, 20, 30, etc.) represents a doubling in algal biomass based on transparency, total phosphorus and chlorophyll-a measurements (Carlson, 1977). Unproductive, oligotrophic lakes score on the lower end of the scale, mesotrophic lakes are in the middle and eutrophic/hyper-eutrophic lakes occupy the upper end of the continuum. The Carlson TSI values were calculated in the same manner as in the 1990 Ohio 305(b) Lakes Report, using formulas from Reckhow and Chapra (Reckhow & Chapra, 1983) as follows: • Secchi disk TSI = 60 - 14.41 ln (SD meters) • Chlorophyll-a TSI = 9.81 ln (Chl-a ug/l) + 30.6 • Total phosphorus TSI = 14.42 ln (TP ug/l) + 4.15 The linear regressions for Carlson’s TSI were calculated using data collected from thousands of lakes in and outside the U.S. The TSI represents absolute values that can be applied to most lakes to characterize their trophic status and general condition. A TSI value was calculated for each of the three variables collected from Willard Reservoir in 2016 (Table 8). Per Carlson’s (1977) recommendation, average summer (July, August, September) chlorophyll-a and spring (April, May, June) total phosphorus TSI values were used to determine the final TSI value.

Such is the case with many lakes and more specifically, reservoirs in Ohio. Trophic State Index ranges based on Carlson’s classification system are as follows:

Oligotrophic (lacking nutrients): Less than 38 TSI Mesotrophic (midrange nutrient availability): 38-47 TSI Eutrophic (nutrient enriched): 48-66 TSI Hypereutrophic (over Enriched): >66 TSI

Since Ohio does not have a very robust baseline of lake data, the use of TSI as a general tool for trend assessment is appropriate. Based on data collected in 2016, the final TSI for Willard Reservoir was calculated to be 40.7. This score indicates a condition low in nutrients, bordering on oligotrophic status, an ideal condition for a drinking water source. Willard Reservoir was sampled as part of a joint lake monitoring effort between the Ohio EPA and the USGS Survey during the summer of 1979. The trophic state index in 1979 was calculated to be 44.0, again mesotrophic. Nutrient concentrations appear to be managed well for this drinking reservoir exhibiting a three- point decrease in TSI over a 40-year period. Conclusion Upground Reservoirs are a reliable way for communities to store surface water prior to its treatment for drinking. Since they are off stream, they have an advantage over traditional impoundments because the quality of inlet water pumped can be somewhat controlled. This is especially true if the source water has seasonally high nitrate levels. These reservoirs are also designed with enough storage capacity to withstand periods of drought. Many upground reservoirs have boat ramps and are stocked with sportfish. While this provides an important source of recreation, all lake management decisions should be made based on drinking water as the primary use.

As lakes age, they naturally become more nutrient rich and productive; this is true for natural lakes as well as artificial lentic systems. Willard Reservoir was built in 1971 and is young in its evolution. The fact that all indicators evaluated were below their associated benchmarks supports this idea. It also shows that the West Branch Huron River is a clean source of inlet water and that pumps are being managed in a wise and effective manner. References
