2012 Tittabawassee, Chippewa, and Pine River Watershed Biosurvey Monitoring Report MI/DEQ/WRD-15/012 REVISED JANUARY 29, 2016 MICHIGAN DEPARTMENT OF ENVIRONMENTAL QUALITY WATER RESOURCES DIVISION APRIL 2015 STAFF REPORT A BIOLOGICAL SURVEY OF THE TITTABAWASSEE RIVER BASIN INCLUDING THE TITTABAWASSEE, CHIPPEWA, AND PINE RIVERS AND SELECTED TRIBUTARIES CLARE, GLADWIN, GRATIOT, ISABELLA, MECOSTA, MIDLAND, MONTCALM, OGEMAW, AND SAGINAW COUNTIES JUNE 2012 Qualitative biological sampling of the Tittabawassee River watershed was conducted by staff of the Surface Water Assessment Section (SWAS) in June 2012, as part of a five-year watershed monitoring cycle. Surveys were conducted on all major tributaries (Tittabawassee, Pine, and Chippewa Rivers) of the watershed (Figure 1). This is a vast watershed that falls within the Southern Michigan Northern Indiana Till Plain (SMNITP), Huron and Lake Erie Till Plain (HELP), and Northern Lakes and Forests (NLAF) ecoregions (Omernik and Gallant, 1988). Land use is predominantly agriculture and forested with portions also being urban. The Tittabawassee River is a major tributary to the Saginaw River/Bay ecosystem. OBJECTIVES This biological survey was conducted to: • Assess the current status condition of individual waters to determine attainment of Michigan Water Quality Standards (WQS). • Evaluate potential impacts from National Pollutant Discharge Elimination System (NPDES)-regulated sources to water quality in the watersheds. • Identify potential nonpoint sources (NPS) of water quality impairment. • Satisfy monitoring requests submitted by internal and external customers. The surveyed locations are illustrated in Figure 1 and Table 1. WATERSHED DESCRIPTION The Tittabawassee River watershed drains approximately 2,100 square miles in east central Michigan and is the largest tributary to the Saginaw River; Michigan’s largest river basin (Creal and Johnson, 1980). This watershed is comprised of three primary subwatersheds: the Tittabawassee, Chippewa, and Pine Rivers. The Pine River is tributary to the Chippewa River, which joins the Tittabawassee River near Midland. The Tittabawassee River subwatershed lies within the NLAF, SMNITP, and HELP ecoregions (Omernik and Gallant, 1988). The Tittabawassee River contains four sizeable impoundments including impoundments on the Tobacco, Cedar, and Sugar Rivers. Approximately 44 percent of land use in the Tittabawassee River subwatershed is classified as agricultural and contains miles of channelized waterways. The Tittabawassee River basin, exclusive of the Chippewa/Pine subwatershed, drains approximately 1,446 square miles in seven counties. The Chippewa River and Pine River subwatersheds lie within the SMNITP and HELP ecoregions (Omernik and Gallant, 1988). Approximately 53 percent and 79 percent of the Chippewa and Pine Rivers subwatersheds, respectively, are used for agricultural production and there are many tributary miles that have been channelized to support agricultural drainage. The Chippewa River subwatershed, exclusive of the Pine River subwatershed, drains approximately 605 square miles in five counties. The Pine River subwatershed is approximately 60 miles long and drains approximately 420 square miles in five counties. HISTORY Previous water quality and biological surveys in the Chippewa River subwatershed have reported good conditions in the headwaters, but impairment from storm water and industrial waste from the city of Mt. Pleasant downstream. Nutrient loading from the North Branch Chippewa River (NBCR) has also been noted in previous surveys (Morse, 1994). The NBCR has been highly modified (straightened, dredged, and defoliated) to facilitate agricultural drainage in many areas. Previous studies in the Pine River subwatershed found severely degraded water quality in the lower reaches of the river from the communities of Alma and St. Louis to the confluence with the Chippewa River (Walker, 2012). While the upper reaches and headwaters of the Pine River support good water quality, the lower reaches remain on the 2010 Clean Water Act Section 303(d) list (LeSage and Smith, 2010) due to mercury found in the water column and restrictions on fish consumption due to PCB contamination. In 2002, biological surveys were conducted at 19 sites in the Chippewa River, and 15 sites in the Pine River, subwatersheds. In total, only one location was rated as having a poor macroinvertebrate community; the remaining locations were rated as having acceptable to excellent macroinvertebrate communities. Previous studies (1997 and 2007) on the Tittabawassee River showed similar patterns in macroinvertebrate community assessments where a majority of sites were rated as excellent or acceptable. Of the 32 sites surveyed in the 1997 study (including the Pine and Chippewa Rivers subwatersheds), none were rated as having a poor macroinvertebrate community. Results for the 2007 biological survey of the Tittabawassee River watershed (including the Pine and Chippewa Rivers subwatersheds) showed 49 of the 52 surveyed sites supported an acceptable to excellent macroinvertebrate community. The three locations that were rated as poor were located in and near the city of Midland and had highly modified stream channels. METHODS Qualitative macroinvertebrate and habitat surveys were performed according to the SWAS Procedure 51 (MDEQ, 1990; Creal et al., 1996). Site selection was made based on the need to gather information on a watershed-wide basis to determine attainment of WQS, identify NPS of water quality impairment, provide information for review of the NPDES permits, and to satisfy outside monitoring requests, where possible. Fourteen sampling locations were randomly selected from a pool of valley segment types represented within the Tittabawassee River watershed to satisfy status monitoring requirements. To develop long-term trend monitoring, 2 10 survey locations from the previous survey (2007) were also sampled in the current survey. In total, 23 locations were surveyed for status and trend monitoring (one location that was randomly selected, by chance, was also a trend site). To satisfy targeted monitoring requests for specific concerns, additional locations were sampled. On the NBCR and Beal City Drain, Procedure 51 analysis and water chemistry samples were performed/collected at two locations. Water chemistry samples were also collected at two other locations on the NBCR. A separate site (Pony Creek at Rolland Road) outside of the planned locations was sampled for water chemistry based on in-the-field concerns. In total, 28 sites were investigated for macroinvertebrates, habitat, and/or water chemistry in this study. RESULTS The locations of the biological sampling stations, habitat observations, and water samples are shown in Figure 1. Table 1 contains a summary of station locations and qualitative ratings for the habitat and biological community for each station. Macroinvertebrate community, physical habitat, and water chemistry data are presented in Tables 2A and 2B; 3A and 3B; and 4, respectively. 3 Figure 1. Map of survey sites for the 2012 Tittabawassee River watershed survey. 4 Status The 2012 Tittabawassee River basin assessment included 14 randomly selected sites for probabilistic monitoring needs where Procedure 51 was conducted. All of the randomly selected sites rated as having acceptable to excellent macroinvertebrate communities. Canham Drain off River Road (Station 2; Figure 2) was rated as having poor habitat while the remaining random sites rated as having marginal to excellent habitat. Canham Drain is a small tributary to the Cedar River near Gladwin, Michigan. Canham Drain appeared to have been dredged and channelized a number of years ago but lack of flowing water appears to be the biggest habitat concern. An interesting situation was found while evaluating a site on Pony Creek near the village of Lake Isabella where the stream crosses Brinton Road. Upon arrival at the site, cattle were observed entering and crossing the stream (Figure 3). Further investigation revealed that cattle had full access to Pony Creek at this location, as the stream was flowing through the middle of a cattle pasture. District staff worked with Department of Agriculture and Rural Development staff to collaborate with the landowner to resolve the issue. Water chemistry samples were collected both at the station and one mile upstream off Rolland Road (Table 4). The macroinvertebrate Figure 2. Canham Drain at River Road (Station 2). community for this station scored excellent while habitat was rated as being marginal (Table 1). Trend For this study, ten sites from the 2007 survey were revisited for trend analysis. Of the ten trend sites, all were found to have acceptable to excellent macroinvertebrates except for Vernon City Creek (Station 5T; Figure 4), which rated poor. Vernon City Creek lies within the city limits of Clare, and has undergone heavy habitat alterations (channelization/straightening, dredging, riparian removal). This site was surveyed following a rain event Figure 3. Cattle Crossing in Pony Creek (Station 3). 5 and petroleum sheen/odor was observed throughout. Overall quality of this stream was quite dismal and habitat was rated as being marginal. Instream substrate observed in the stream, however, was depauperate of macroinvertebrates. This site was visited during the 2007 survey where it had scored on the low end of acceptable. Other than the Vernon City Creek trend site, the remaining trend locations had similar scores between the 2007 and 2012 sampling. Two sites were rated as having excellent Figure 4.

  • Saginaw River Dredge Disposal Project at Saginaw Bay, Michigan
    ' SAGINAW RIVER DREDGE DISPOSAL PROJECT AT SAGINAW BAY, MICHIGAN FINAL ENVIRONMENTAL IMPACT STATEMENT FEBRUARY 1 ^4/ PREPARED BY U.S. ARMY ENGINEER DISTRICT DETROIT, MICHIGAN STATEMENT OF FINDINGS PROPOSED DREDGE DISPOSAL FACILITY SAGINAW BAY, MICHIGAN I have reviewed and evaluated, in light of the overall public interest, the documents concerning the proposed action as well as the stated views of other interested agencies and the concerned public relative to the proposed dredge disposal fa cility at Saginaw Bay, Michigan. BACKGROUND Construction of the proposed facility is authorized by the River and Har­ bor Act of 1970 (Public Law 91-611, Section 123) which provides for the confined disposal of polluted materials resulting from maintenance dredg­ ing of Federal navigation projects. Additionally, in 1970, the Governor of Michigan requested that the Corps of Engineers cease returning polluted dredged materials to the waters of the Great Lakes in Michigan. As part of the planning process for the proposed fa cility, two workshops were con­ ducted at Bay City in March 1974. These meetings were attended by govern­ ment representatives, city representatives, environmental groups and the general public. The purpose of the meetings was to provide and exchange information relative to the alternatives being considered for siting the facility. As a result of information generated at the workshops and con­ tinued coordination with the State of Michiv,—., the Channel-Shelter Island location was selected. THE SELECTED PLAN -The proposed disposal site is located on the southeast side of the Federal navigation channel in Saginaw Bay, approximately two miles northeasterly from the mouth of the Saginaw River.

Box 30028 Lansing, Michigan 48909 PREFACE This Saginaw RiverIBay Remedial Action Plan (RAP) was prepared by the Michigan Department of Natural Resources (MDNR) from a first draft compiled for MDNR by the East Central Michigan Planning and Development Region, the National Wildlife Federation, and graduate students from the University of Michigan. The Remedial Action Section was prepared by MDNR and a regional public organization known as the Saginaw Basin Natural Resources Steering Committee. Public and technical comment was received throughout the RAP development and review process as described in Section VI. The RAP summarizes existing water quality data on the Saginaw Bay drainage basin and outlines initial perceptions of the remedial actions that should be taken to further address the eutrophication and toxic material problems in the Saginaw River and Saginaw Bay. The remedial actions presented here will be further refined in future versions of the RAP, which it is anticipated, will be periodically updated and revised as more data are acquired, remedial measures are implemented, and environmental conditions improve. ACKNOWLEDGEMENTS An extensive list of people and agencies contributed a great deal of time and effort to develop this plan. The complete list is too extensive to present

Their historic range included drainage basins of the Mississippi, Hudson Bay, and the Great Lakes (MacKay 1963; Scott and Crossman 1973). Within the last century, lake sturgeon populations were dramatically reduced or extirpated from much of their native range (Harkness and Dymond 1961; Brousseau 1987). Habitat destruction, excessive harvesting, and over fishing were determined to be the primary causes for their decline (Harkness and Dymond 1961; Tody 1974; Brousseau and Goodrich 1989). To slow the decline of lake sturgeon, state governments in the United States and provincial governments in Canada have listed them as a protected species (Brousseau 1987; Johnson 1987). Lake sturgeon are protected from harvest in seven of the eight Great Lakes border states, and have recently been listed (July 2008) as threatened under the Species at Risk Act (SARA) in the Canadian jurisdictional waters of the Great Lakes (Thomas Pratt personal communication). They are also listed as a state threatened species in Michigan (Auer 1999). From historical records on Lake Huron, lake sturgeon spawned on at least 40 tributaries in the United States and Canada, of those 24 were located in Ontario waters with the remaining 16 located in Michigan waters (Hay-Chmielewski and Whelan 1997; Holey et al.
