GENERAL DISCUSSION:
Temperature, pH, dissolved oxygen, and conductivity measurements are displayed in monthly profile graphs at the end of this chapter. In 2005 the lake thermally stratified from May through August. This means that the lake developed a warm surface layer as solar radiation warmed the upper water, but the bottom water stayed cool. Because of its dark color, Black Lake water gets very warm. The surface water reached a high of 25.8 degrees Celsius in August, but the bottom layer of water (hypolimnion) remained much colder, at 16 degrees. The lower layer of colder water, generally below 5 meters, was very low in oxygen throughout the summer. This condition results in a slow release of phosphorus from the sediments into the water near the bottom. This can be seen in the higher concentrations of phosphorus in the bottom samples (see data on the data report page). The release of nutrients from the sediments stimulates algae productivity in the lake, especially in late summer when the lower and upper waters mix. In October 2005 the high chlorophyll concentrations and low water clarity shows that an algae bloom did occur when the two layers mixed.
The Carlson trophic state indices (TSI), are used to express the degree of productivity of a lake. Average summer total phosphorus concentrations, chlorophyll a concentrations, and secchi disk transparency are each used to calculate a TSI for the lake. A TSI of 0 to 40 indicates an oligotrophic, or low productivity, lake. A TSI of 41 to 50 indicates a mesotrophic, or moderately productive lake. A TSI of greater than 50 indicates a eutrophic, or highly productive lake.
In 2005, the TSI’s for total phosphorus, chlorophyll a, and secchi disk were 51, 58, and 50, respectively. All three TSIs were in the eutrophic category or highly productive category. The trophic state indices graph, on the page following the profile graphs, show that in most years the lake has been at the upper limit of the mesotrophic range with some year-to-year variations that push well into the eutrophic range.
The average water clarity for the 2005 season was 2 meters (6.6 feet). It ranged from 1.4 meters in October to 3 meters in August (4.6 to 9.7 feet). The graph at the end of this chapter shows the annual average for the period of record. The water clarity trend graph, which normalizes the annual averages using the long-term mean shows no obvious trend in water clarity over the period of record.
43 Black Lake
Algae types common to Black Lake include diatoms, green and blue-green algae. However, during the peak chlorophyll production, the blue-green algae Aphanizomenon or Anabaena are usually the dominant algae responsible for the “algae blooms”. Dominance of the algae population by blue- green algae is generally considered a sign of nutrient-rich conditions and poor water quality. At times in the past, algal growth has impaired recreational uses of the lake due to poor water clarity, algae scums on the water surface, and odor. This was particularly true in 1992, 1994, and 2000. In September 2000, there was a spectacular blue-green algae bloom that covered much of the western shore of the lake. At the point of algae die-off, it resembled a turquoise-blue paint spill, which drew citizen and media attention. In August 2004, another, but lesser bloom, resulted in closure of the swimming area at the County Park.
Major Issues:
Major blue-green algae blooms that occur during late summer and fall interfere with the recreational uses of the lake.
Occasional beaver activity in the lake outlet ditch to the north causes lake levels to rise resulting in flooding of yards and docks. Thurston County Roads and Transportation Department is responsible for maintaining the ditch.
Swimmer’s itch is reported to be a regular summer problem in this lake, so preventative measures should always be taken by bathers.
Funding Sources:
Sampling was funded by Thurston County, and will continue to be supported in 2006.

The water quality standard for fecal coliform has two parts: part I - the geometric mean shall not exceed 100 org/100mL and, part II - no more than 10% of the samples shall exceed 200 colonies/100mL. In water year 2004/05, eight samples were collected. One sample exceeded 200 colonies/100 m, which violates part II of the water quality standard. However, the stream met part I of the standard with a geometric mean of 36. The standard for pH requires the pH to be within the range of 6.5 to 8.5. There were no pH violations in 2005. The water quality standard for dissolved oxygen is a lowest one-day minimum of 8 mg/L. Dissolved oxygen measurement in July and August were below the minimum allowable concentration. The water temperatures in the stream in July and August were also higher than the 17.5 degree Celsius water quality standard, with temperatures over 19 degrees. Because the ditch originates from Black Lake, these high temperature and low dissolved oxygen measurements reflect conditions typical of a lake environment.
Major Issues:
# The basin is within the urban growth boundary and is rapidly developing. The City of Olympia has a major regional stormwater facility along Black Lake Ditch that treats and detains storm water that comes from commercial development on the west side of Olympia.
# Black Lake Ditch is included in a total maximum daily load study (TMDL) begun in 2003 by the Washington Department of Ecology to identify pollution sources and develop a plan to correct them. Because Black Lake is the origin of the Black Lake Ditch, high summer temperatures and low dissolved oxygen are a common condition.
# Homeless encampments within the riparian corridor are a common occurrence and could be contributing to water quality problems.

OTHER AVAILABLE DATA:

GENERAL DISCUSSION:
Background The area of Capitol Lake was formerly an estuary of Budd Inlet. The lake was formed by the construction of a tide gate in 1951, which impounded the Deschutes River. The tide gate was constructed to create a reflection pond for the state capitol building. The resulting body of water looks like a lake but the water passes through the lake and discharges through the tide gate into Budd Inlet. During high winter flows in the Deschutes River the water exchange in the lake can be as fast as 0.2 days. During the summer low-flow period the exchange rate is much slower, and can be as slow as 9 days.
Capitol Lake has several water quality problems. As an impoundment of the Deschutes River, Capitol Lake shares some of the river’s characteristics, such as elevated nutrient levels, and high turbidity during winter storms. The lake is gradually filling with sediment transported into it by the Deschutes River and Percival Creek and other smaller sources. The wide shallow basins lead to high surface water temperatures and allow light to reach the bottom of most of the lake. This provides excellent habitat for aquatic plants and algae, which impair some of the uses of the lake. Until 1985, a swimming area was operated by the City of Olympia at the north end of the lake. However, poor water clarity and high fecal coliform bacteria levels forced the closure of the swimming area. Water circulation into and out of the swim area was poor, and likely contributed to its chronic water quality problems.
Likely sources of bacteria and nutrient pollution to the lake include: agricultural activities along the Deschutes River and its tributaries, septic systems, resident waterfowl on the lake, highway and urban stormwater runoff, accidental spills, inadvertent sewage discharges, and other nonpoint pollution sources.
To reduce the water quality impact from stormwater discharges, the City of Olympia constructed a regional stormwater detention/wetland system along Black Lake Ditch in the early 1990's. In 2003, the City of Olympia initiated an illicit discharge detection and elimination program to identify and 60 Capitol Lake 2005
eliminate sewer connections to the city storm sewer systems. Since the programs inception several illicit connections have been found and eliminated. As part of this new program, a major storm sewer system which discharges into Capitol Lake near 7th Avenue and Water Street was investigated for possible sewer connections and damaged pipes in late 2004 and 2005. Two damaged pipes were found and repaired. The system will continue to be monitored and potential pollution sources investigated. The City of Tumwater currently has plans to build regional stormwater facilities to address discharges into both Percival Creek and the Deschutes River.
2005 Ambient Monitoring Program
The 2005 ambient monitoring schedule included monthly sampling from May through October at sites in the middle of the north and middle basins and in Percival Cove. In addition, 48-hour deployment of a monitoring instrument in the middle of the north basin to record dissolved oxygen conditions levels. The 2005 ambient sampling data is included at the end of this narrative.
After several years of documenting that nutrient levels are fairly uniform vertically through the water column, the sampling protocol was changed in 2005. Nutrient samples this year were collected at a single depth of one meter rather than at two depths. This single depth sampling protocol for nutrients will continue to be used in future monitoring years.
Field Parameters
Capitol Lake does not thermally stratify as do most Thurston County lakes, due to its shallow depth and riverine influence. The water quality throughout the water column is fairly uniform at all three sites. The north basin being the deepest occasionally has some variability vertically through the water column. During June and October, evidence of salt water was noted at the lake bottom at the north basin site. The tide gate at the lake outlet normally prevents marine water from flowing into the lake. However, during high tides greater than 14 feet, salt water flows over the fish ladder and into the lake, where it settles into the deepest part of the lake.
In July 2004 the lake was treated with the herbicide, triclopyr, to control eurasian water milfoil. Because of the herbicide treatment, 2004 was an atypical year for water quality conditions. Dissolved oxygen, pH, and chlorophyll production were very high in August and September likely in response to nutrients made available due to die off of milfoil. By 2005 other aquatic plants had re- established, and an algae bloom the magnitude of the previous year did not reoccur.
In follow-up to the high dissolved oxygen levels measured in 2004, a monitoring instrument was deployed in August 2005 for a 48-hour period in the north basin to record peak and daily fluctuations. The graph below shows the dissolved oxygen measurements for that continuous monitoring. The levels ranged from 10.89 to 12.22 mg/L, which reflects 122 to 140 percent saturation. The mean oxygen level was 11.60 mg/L. An instantaneous measurement in mid- September reached 14.15 mg/L. The previous year, in August 2004, after the herbicide treatment, the dissolved oxygen range in the north basin was much wider, from 6.7 to 16.9 mg/L. During September 2003, an instantaneous measurement of 17.08 mg/L was recorded in the north basin, and readings in the middle basin reached 16.45 mg/L. Similar levels were measured in 2000, before milfoil was discovered in the lake. It appears that high dissolved oxygen levels during late summer are typical conditions for Capitol Lake.

The Carlson trophic state indices (TSI), are used to express the degree of productivity (algae, aquatic plants, etc.) of a lake. Average summer total phosphorus concentrations, chlorophyll a concentrations, and secchi disk transparency are each used to calculate a TSI for the lake. A TSI of 0 to 40 indicates an oligotrophic, or low productivity, lake. A TSI of 41 to 50 indicates a mesotrophic, or moderately productive lake. A TSI of greater than 50 indicates a eutrophic, or highly productive lake. Due to the shallow condition of Capitol Lake and the dense rooted aquatic plant growth that occurs, the secchi disk often either reaches the bottom of the lake or is obscured by plants. Since these measurements are not a true representation of water clarity, the secchi disk TSIs are not reported.
The north basin’s 2005 TSIs for average total phosphorus and chlorophyll a are both 59. The middle basin has TSI values of 57 and 48 for total phosphorus and chlorophyll a, respectively. Percival Cove’s 2005 TSI for average total phosphorus and chlorophyll a are 62 and 58 respectively. The TSIs show that the lake basins are in a eutrophic, or highly productive, condition. Percival Cove shows the greatest productivity. In 2005, the chlorophyll TSIs were lower in all basins than they were in 2004 when a severe algae bloom occurred after the milfoil herbicide treatment. Graphs of the yearly TSIs for each basin since 1999 are included at the end of this chapter.
Water Clarity
The graph on the next page shows the 2005 monthly water clarity measurements in the north basin. The standard that is generally applied to bathing beaches is a water clarity of at least four feet. The poorest water clarity measured this season was in June, one meter (3.3 feet). The clarity was also less than four feet in September. The highest water clarity measurement was in August, two meters (6.4 feet). The season average was 1.4 meters (4.6 feet). A graph of the summer average water clarity for the past six years can be found at the end of the narrative.

Fecal Coliform Bacteria
Fecal coliform bacteria samples are collected as part of the monitoring program because of the historic use of the lake for water contact recreation. Additionally, the lake is listed on the Washington Department of Ecology 303(d) list of impaired water bodies for fecal coliform bacteria violations. The results from this year’s bacteria sampling are shown in the table below. The state water quality standard for primary contact recreation is 50 fecal coliform organisms per 100 ml with not more than ten percent of the samples exceeding 100. The county policy regarding closure of a bathing beach sets the fecal coliform standard at a geometric mean of 200 organisms per 100 ml. Bacteria levels measured in Capitol Lake from May through October 2005 were within the state water quality standard and met the Thurston County bathing beach policy. Fecal coliform bacteria results from the past six years are included in a table in the data section at the end of this report.

Major Issues:
A 10-year plan for adaptively managing Capitol Lake was developed by the Washington Department of General Administration and a multi-agency steering committee. The goal of the plan is to achieve measurable improvements in flood control, water quality, salmon enhancement, sediment management and infrastructure improvements. The plan identifies fourteen management objectives, which have been adopted by the State Capitol Committee and are being implemented by the Washington State Department of General Administration and the other participating agencies.
A study to examine the feasibility of returning the lake to a naturally functioning estuary is being pursued. The projected completion date for the currently funded tasks is the end of 2006.
Some of the past and present Capitol Lake management issues include: Sediment deposition and dredging Poor water quality Controlling the population of resident Canada and domestic geese Accidental sewage and chemical spills Control of aquatic plant and algae growth by saltwater flushing Invasion of noxious weeds such as purple loosestrife and Eurasian water milfoil Flooding and lake shoreline erosion Chinook salmon hatching and rearing operation Stormwater discharges
In mid 2003, the brewery operation just upstream of the lake closed and ceased discharge to the Deschutes River.
In 2001 Eurasian water milfoil, an exotic aquatic plant, was discovered in the lake. In summer 2004, the herbicide, triclopyr, was applied to the lake to control the milfoil infestation. In 2005, some surviving milfoil plants were discovered in the south basin and in the wetland near the Interpretive Center.
Funding Sources:
Funds for water quality monitoring in 2005 were provided by the State of Washington Department of General Administration.

Nitrate concentrations continue to be higher than is usual for most surface water streams. In 2005 the average was 1.8 mg/L and the highest result in January was 3.7 mg/L. The source of the nitrates is most likely from contamination of the shallow groundwater that provides the base flow for the creek. An examination of the nitrate pattern shows that nitrates are higher during periods of low flow and low rainfall when dilution with low concentration rain water is minimal.
Major Issues:
# High nitrate concentrations at the mouth.
# Development in the basin, which is expected to occur at a rapid rate since most of the basin is within the urban growth boundary, may impact stream quality.
# Chambers/Ward/Hewitt Comprehensive Drainage Basin Plan was completed July 1995, which included recommendations to address flooding and water quality issues.
Funding Sources:
# Local stormwater utility rate

The Deschutes River is being monitored near its mouth just above the Tumwater Falls at “E” Street as part of the county long-term ambient monitoring program. Historical water quality data collected by Thurston County is reported in two documents, Budd Inlet/Deschutes River Watershed Characterization Part II Water Quality Study, March 1993 and Addendum (to the March 1993 report), October 1995.
Various segments of the Deschutes River are listed on Washington State Department of Ecology’s 1998 Section 303(d) list of impaired and threatened water bodies for violating temperature, pH, and fecal coliform water quality standards, as well as in-stream flow, fine sediments and large woody debris deficiencies. In response to those listings the Washington Department of Ecology began a total maximum daily load study (TMDL) in 2003. The TMDL project is anticipated to be a four year process to identify pollution sources and develop a plan to correct them.

Between 1992 and 1998, Ellis Creek was monitored each water year as part of the ambient monitoring program funded by the local storm and surface water utilities. The creek is now monitored every other year. Part II of the fecal coliform bacteria standard was violated this water year. Other water quality conditions were within the standards. Visual observations made by field staff indicate that the bottom substrate of the stream channel has changed over time from predominantly gravel to sand.
Major Issues:
# Because of it proximity to the city limits, new development is occurring in the watershed. Full development of the basin could have an appreciable impact on flood volumes.
# Water quality is threatened by erosion from high stream flows and nonpoint source pollution in the watershed.
# Stream bed appears to be changing from predominantly gravel to fine sand.

Between 1992 and 1998, monitoring of Mission Creek was conducted during each water year as part of the ambient monitoring program. The creek is now monitored every other year. Both parts of the state fecal coliform water quality standards were violated during water year 2004/2005. Nutrients are elevated in this creek, particularly nitrates.
In the past, Mission Creek was monitored as part of the Budd/Deschutes Water Quality Study, 1993. The creek was found to contain one of the highest loadings of fecal coliform bacteria to Budd Inlet of all tributaries to Budd Inlet. This creek was intensively monitored during storms. The intensive monitoring revealed that there were excessively high levels of bacterial contamination throughout the creek system and that stormwater was the major source of bacterial contamination to the creek. An area-wide septic system survey done as a follow-up to the intensive monitoring did not identify major septic system failures that would explain the high levels of bacteria in the creek.
Major Issues:
# High levels of bacterial contamination throughout the creek system, including stormwater discharges.
# The watershed has potential for future development which may further impact water quality.
Funding Sources:
# Local stormwater utility rate

Moxlie Creek is part of the ambient monitoring program, and is monitored every other water year. No sampling was done during 2003-04. The sampling site is at the outfall pipe at Marine Drive where the creek discharges into Budd Inlet. This site can only be monitored during a low tide, otherwise the outfall is submerged. In the past, Moxlie Creek was sampled at Plum Street just before the creek entered the 72 inch pipe under the city. However, sampling at that location missed approximately three-quarters of a mile of the lower creek that is particularly vulnerable to sewer cross-connections and storm water run-off.
The creek failed both parts of the fecal coliform bacteria standard in water years 02/03 and 04/05. Fecal coliform bacteria concentrations are very high in this creek. Total phosphorus concentrations are elevated above levels measured in the majority of Thurston County streams.
Major Issues:
# Stormwater discharges to the creek threaten the integrity of the natural creek channel in the upper watershed and degrades water quality throughout its length.
# The lower portion of the creek is confined in a 72" culvert under the city, which provides little habitat value.
# Illicit connections of sewer lines to the culverted portion of the creek is an on-going problem.

117 Schneider Creek #0009 (Budd Inlet Watershed)
From 1993 - 1998, the creek was monitored each water year as part of the long-term ambient monitoring program. The creek is now monitored every other year. Part II of the fecal coliform water quality standard was not met in water year 2004/2005. At around one milligram per liter, the nitrate concentration in this creek is above typical surface water levels. It likely reflects the nitrate concentrations in the shallow ground water which provides base flow to the creek. During the winter months the creek is highly impacted by peak storm water flows that scour the stream channel.
Major Issues:
# High volumes of stormwater discharging directly to the creek are causing bank failures, streambank erosion, flooding, stream channel scour, and water quality degradation.
# City of Olympia constructed a stormwater treatment facility at the headwaters of the creek to improve the quality of urban stormwater discharging to the creek.
Funding Sources:
# Local Stormwater Utility

122 Spurgeon Creek #0037
The water quality standard for fecal coliform bacteria has two parts: part I - the geometric mean shall not exceed 100 colony forming units (cfu) /100 mL and, part II - no more than ten percent of the samples shall exceed 200 cfu/100mL. The geometric mean for the 2004-05 water year was 54 cfu/100ml with one sample out of eight (12%) greater that 200. So the creek met part I of the standard but failed part II.
The water quality standard for dissolved oxygen is a lowest one-day minimum of 8 mg/L. All measurements recorded in 2004-05 were above the minimum allowable level. There were no recorded violations of dissolved oxygen in the historic data record from 1990 through 1998.
The Class A standards for pH requires the pH to be within the range of 6.5 to 8.5. There were no violations during the past water year, and only one violation in period of record.
Monitoring of Spurgeon Creek was resumed as part of Thurston County’s ambient monitoring program this year. The creek is also part of a water quality study being conducted by the Washington Department of Ecology.
Major Issues:
# Nonpoint pollution from rural residential and agricultural activities.
# Encroachment on wetlands and natural riparian areas for livestock grazing and other uses may impact water quality.
# Spurgeon Creek is included in a total maximum daily load study of the Deschutes Watershed (TMDL) begun in 2003 by the Washington Department of Ecology to identify pollution sources and develop a plan to correct them.

GENERAL DISCUSSION:
Ward Lake is a steep-sided spring-fed glacial depression, or kettle. It has no surface inlet or outlet. Nutrient levels are low. The lake supports only a light growth of aquatic plants, limited in large part by the depth of the lake. Algae blooms are not common but occasionally moderate densities of algae are observed, especially during the winter.
The lake stratifies into two distinct layers of water during the summer months, May through October. In 2005, the warmer surface water layer (called the epilimnion) extended from the surface to a depth of about 6 meters. The warmest water temperature at the surface reached 24.8 degrees Celsius in August. Water temperature at the bottom remained at about 7 degrees Celsius. The lower colder layer of water was anoxic (contains very low or no levels of dissolved oxygen) during the period of thermal stratification. Bacterial decomposition of aquatic plants, algae and other organic material uses and depletes the dissolved oxygen in the water near the bottom. This anoxic condition results in solubilizing phosphorus in the sediments as release into the water, as can be seen by the high total phosphorus concentrations in the bottom samples (See the data report at the end of this narrative.). These additional nutrients in the water column can stimulate algae growth after the lake mixes in late fall or early winter.
In 2005, the water clarity (measured by secchi disk readings) ranged from 1.9 meters (6.3 feet) in May to 5.7 meters (18.7 feet) in September. The average for the season was 4.6 meters (15 feet). The secchi disk readings graph on the page following the field measurement profiles shows the average annual secchi disk measurements for 1992 and 1995 through 2005. The average water clarity in 2005 was the lowest it has been since 1999. However, the water clarity trend graph, included at the end of the narrative, does not indicate an obvious upward or downward trend in the ten year period of record.
The average total phosphorus concentration in the upper water of the lake was 0.008 milligrams per liter (mg/l) in 2005. This lake has very low phosphorus concentration which is one indicator of good water quality. The average 2005 chlorophyll a concentration was 4.4 micrograms per liter (µg/l), which is also very low. Chlorophyll a is the green pigment found in plants, including algae, and is used as a measure of the amount of algae growth in a lake. This year May was the month with the highest chlorophyll level at 15 micrograms per liter.
The Carlson trophic state indices (TSI), are used to express the degree of productivity of a lake. Average summer total phosphorus concentrations, chlorophyll a concentrations, and secchi disk transparency are each used to calculate a TSI for the lake. A TSI of 0 to 40 indicates an oligotrophic, or low productivity, lake. A TSI of 41 to 50 indicates a mesotrophic, or moderately productive lake. A TSI of greater than 50 indicates a eutrophic, or highly productive lake. Eutrophic lakes are generally considered to have poor water quality.

The 2005 TSIs for total phosphorus, chlorophyll a, and secchi disk transparency measurements were 34, 45, and 38 respectively. These TSI’s show that Ward Lake is primarily in the oligotrophic (or low productivity) category. The trophic state indices graph on the page following the field measurements profiles show the TSIs since 1995, which vary on a year-to-year basis but indicate no major shift in water quality.
At the end of this chapter is a report of the algae species present in the lake samples. Lakes with higher nutrient levels and poorer water quality tend to be dominanted by blue-green algae. Blue- green species were present in all but one monthly sample, but they were not the dominant algae. Green algae are more common in oligotrophic lakes, and there were several species of these algae present also. The composition of the algae species in Ward Lake will be examined over time to watch for any shift from green algae dominance to blue-green algae dominance. Such a shift may indicate that the lake is becoming more nutrient-rich and changing from a low productivity state to a higher productivity state.
Major Issues:
The lake is located in a basin that is developing rapidly. Stormwater flows directly into Ward Lake in at least three locations from high density residential areas. Currently, a planned urban village is under construction on the west side of the lake on a site that had formerly been a landscape plant nursery. Spills and storm-related sewage spills have occurred into Ward Lake in the past.
Conflict between lake users at the Department of Fish and Wildlife public access have been a controversial issue.
Ward Lake is listed on Washington State’s Clean Water Act Section 303(d) list of impaired water bodies for excursion above the edible fish tissue criteria for polychlorinated biphenyls (PCB’s). The source of the PCB’s is undetermined. The contact agency for this listing is the Washington State Department of Ecology.
Funding Sources:
County funds will continue to support monitoring in 2006.
