Watershed Detail - Turtle Creek

Watershed - Turtle Creek (LR01)

Details

This watershed's 288 square miles are in eastern Walworth County (62%) and Rock County (38%). Land use is primarily cash crop and dairy agriculture throughout the headwater tributaries and creek main stem. Turtle Creek flows into the east side of the city of Beloit to join the Rock River just above the Illinois border. Cropland in the headwater areas and urban land use near Beloit contribute the two highest erosion rates in the watershed. Also, streambank erosion is a problem. A 1982 inventory showed that 10 percent of streambanks in the watershed were eroding (Rock Co. Erosion Control Plan). In 1986, this watershed experienced an estimated average soil loss of 8 tons/acre/year. A priority watershed project under the Wisconsin Nonpoint Source Water Pollution Abatement Program began in 1984 and was completed in 1994. The project, jointly administered by the Rock and Walworth County Land Conservation Departments and WDNR, had four water quality and water use objectives: 1. Improve the smallmouth bass fishery in main stem Turtle Creek and Little Turtle Creek; 2. Protect and improve fish habitat and water quality of tributaries to Turtle Creek; 3. Protect and improve fish habitat in creeks that currently support remnant populations of Wisconsin's endangered and threatened fish species; and 4. Retard the eutrophication process in Lakes Delavan and Comus. According to the 1994 post-project evaluation report, the effectiveness of best management practice implementation was evident on a site-by-site basis, but there was no discernible watershed-wide reduction in nonpoint source (runoff) pollutant loads. Low participation rates and implementation of best management practices that brought landowners short-term benefits are sited as reasons for this result. Poor livestock management practices, such as cropping too close to stream channels, overgrazing of pastures, and livestock grazing in streambanks in headwater streams, limited the overall effectiveness of the project.

Population, Land Use

Although the Southeast Glacial Plains Region is quite urban compared to other state areas, agriculture is very important with 77% of land area in the Turtle Creek Watershed devoted to farmland. Among the regions it ranks third in percent of acreage in farmland, market value of agricultural products per acre, and milk production per acre; and it ranks second in corn production. (Farmland includes all land under farm ownership such as cropland, pastureland, and woodland.) The percentage of agricultural land sold and diverted to other uses is below average. Per capita water use is near average. The per capita income, average wage, and number of high school and college graduates are all third highest, while the rates of poverty and unemployment are both third lowest among the regions. The manufacturing sector is relatively strong, whereas farming, though very productive, does not provide a large percentage of jobs. After agriculture, forest cover accounts for the second largest share of land use in the Turtle Creek Watershed with eight percent of the total area. Open water and open space is the third most common land use in the watershed with six percent of the total area. Suburban and urban environments amount to another six percent of the watershed’s area. Grasslands and wetlands are the last significant land uses in the watershed with three percent and one half of one percent of the watershed’s area, respectively. Turtle Creek Watershed’s largest water resource, Delavan Lake, has a watershed (drainage area) of about 26,000 acres or 40.8 square miles. As of 1995, approximately 85% of the lake’s watershed consisted of rural land uses, and 15% of urban land uses. Major land uses included: 70% agriculture, eight percent woodlands, wetlands or open lands, seven percent residential, and eight percent commercial, industrial, transportation, and recreational. Under planned 2020 conditions, the Walworth County development plan and regional land use plan forecast 6,200 acres (24 percent of total area) of development within the watershed (SEWRPC 2002).

Nonpoint and Point Sources

The Turtle Creek Watershed is listed as a high priority overall for nonpoint source (NPS) pollution due to its listing as a high priority for groundwater and stream NPS pollution. Individual streams and lakes in the watershed have not yet been ranked for NPS pollution. CAFOs A Concentrated Animal Feeding Operation (CAFO) owned by S & R Egg Farms, Inc. is located in the township of La Grange, just east of Whitewater. This CAFO has a permit for animal waste/industrial water discharge to groundwater.

Ecological Landscapes

The Lower Rock Basin resides in the Southeast Glacial Plains Ecological Landscape, which makes up the bulk of the non-coastal land area in southeast Wisconsin. This Ecological Landscape is made up of glacial till plains and moraines. Most of this Ecological Landscape is composed of glacial materials deposited during the Wisconsin Ice Age, but the southwest portion consists of older, pre-Wisconsin till with a more dissected topography. Soils are lime-rich tills overlain in most areas by a silt-loam loess cap. Agricultural and residential interests throughout the landscape have significantly altered the historical vegetation. Most of the rare natural communities that remain are associated with large moraines or in areas where the Niagara Escarpment occurs close to the surface.

Date 2010

Hydrologic Features

The Southeast Glacial Plains has the highest aquatic productivity for plants, insects, invertebrates, and fish, of any Ecological Landscape in the state. Significant river systems include the Mukwonago, Wolf, Sheboygan, Milwaukee, Rock, Sugar, and Fox. Most riparian zones have been degraded through forest clearing, urban development, and intensive agricultural practices. The Ecological Landscape contains several large lakes, including those in the Madison area and in the Lake Winnebago Pool system. These lakes are important to many aquatic species including the lake sturgeon. Kettle lakes are common on end moraines and in outwash channels. In addition to Horicon Marsh, this Ecological Landscape contains important fens, tamarack swamp, wet prairies, and wet-mesic prairies that contain rare plants and animals. However, most wetlands have experienced widespread ditching, grazing, and infestation by invasive plants. Watershed pollution in the Ecological Landscape is about average according to rankings by Wisconsin DNR, but groundwater pollution is worse than average compared to the rest of the state.

Impaired Water in Turtle Creek Watershed

River and Stream QualityAll Waters in Watershed

According to the WDNR’s Register of Waterbodies (ROW) database, there are over 335 miles of streams and rivers in the Turtle Creek Watershed; 122 of these waters have been entered into the WDNR’s assessment database. Of these 122 miles, almost 70% are meeting Fish and Aquatic Life uses and are specified as in “good” condition; about nine percent of streams are considered to be in “poor” condition and are listed as impaired. The condition of the remaining stream miles is not known or documented. Potawatomi Creek is considered an Outstanding Resource Waters for one mile of its length and there are over 40 stream miles of Exceptional Resource Waters spread along segments of the Turtle Creek, Little Turtle Creek, Spring Brook, and an unnamed tributary to Turtle Creek. Potawatomi Creek claims the only mile of documented trout waters in the watershed as it is a Class I Trout stream. Impaired waters account for about 11 stream miles along Turtle Creek due to excess phosphorus loads, which is why a restoration area has been designated along the creek.

Lakes and Impoundments

The WDNR’s ROW database shows that there are 2,137 acres of lakes and ponds, 151 acres of reservoirs and flowages, and another 351 acres of unspecified open water in the Turtle Creek Watershed. Approximately 2,644 lake acres are entered into the state’s assessment database. Most of these waters (86%) are indicated as supporting fish and aquatic life uses. A couple hundred have not been assessed for fish and aquatic life use, yet, and none of the lake acres have been assessed for any other use. Three large lakes can be found in the Turtle Creek Watershed: Comus Lake, Delavan Lake, and Turtle Lake. Five sensitive areas have been designated on Delavan Lake.

Wetland Health

Wetland Status: The Turtle Creek Watershed is located in eastern Walworth County and Rock County. Approximately three percent of the current land uses in the watershed are wetlands. Currently, only about 23% of the original wetlands in the watershed are estimated to exist. Of these wetlands, the majority include emergent wetlands (42%), which include marshes and wet meadows, scrub wetlands (30%), and forested wetlands (25%). Wetland Condition: Little is known about the condition of the remaining wetlands but estimates of reed canary grass infestations, an opportunistic aquatic invasive wetland plant, into different wetland types has been estimated based on satellite imagery. This information shows that reed canary grass (RCG) dominates 35% of the existing emergent wetlands, 15% of shrub wetlands, and 7% of the remaining forested wetlands. Reed canary grass domination inhibits successful establishment of native wetland species. Wetland Restorability: Of the 17,671 acres of estimated lost wetlands in the watershed, approximately 60% are considered potentially restorable based on modeled data, including soil types, land use and land cover (Chris Smith, DNR, 2009).

Date 2011

Impaired Waters

About a ten mile stretch of Turtle Creek is listed on the impaired waters list for a high total phosphorus load leading to low dissolved oxygen in the water. The source of the impairment is a combination of municipal point discharges and nonpoint sources (e.g. agricultural and stormwater runoff).

List of Impaired Waters

Aquatic Invasive Species

Exotic species, most notably zebra mussels, Eurasian water-milfoil, and purple loosestrife have invaded southeastern Wisconsin lakes. Boaters traveling from lake to lake often facilitate the propagation of exotic species. The introduction of exotic species into a lake ecosystem can lead to a decline in the native plant population and cause problems with nutrient loading. In addition, the disturbance of lake bottoms from human activity (boating, plant harvesting, chemical treatments, etc.) enhances the colonization and/or expansion of exotic species. Two simple steps to prevent the spread of exotic species include 1) Removing aquatic plants, animals, and mud from trailers and boats before leaving the boat access; and 2) Draining water from boats, motors, bilges, live wells, and bait containers before leaving the water access. Eurasian water-milfoil can be found in four of the sensitive areas on Delavan Lake. Eurasian water-milfoil is one of eight milfoil species currently found in Wisconsin. It is often misidentified as one of its seven native cousins, and vice versa. In many areas within the lake, this non-native milfoil has established large monocultures and has out competed many native plants. These dense beds of milfoil not only impede the growth of native plant species but also inhibit fish movement and create navigational problems for boaters. The regenerative ability of Eurasian water-milfoil is another obstacle when attempting to control this species. Fragments of Eurasian water-milfoil detached by harvesting, boating, and other recreational activities can float to non-colonized areas of the lake or downstream to additional lakes in the drainage system and create new colonies. Therefore, when controlling Eurasian water-milfoil, selective chemicals and harvesting, coupled with skimming, often produces the best results. In some lakes, biological agents such as the milfoil weevil have helped suppress milfoil populations. However, the most effective “treatment” of exotic milfoil is prevention through public education. Curly-leaf pondweed is another submerged, exotic species found in Delavan Lake. Like Eurasian water-milfoil, curly-leaf often grows into large, homogenous stands. It can crowd out native vegetation, create navigational problems, and limit fish movement. Curly-leaf pondweed dies off in mid-summer, increasing nutrient availability in the water column. This often contributes to summer algal blooms and decreasing water quality. The unusual life cycle of curly-leaf pondweed makes management difficult. The plant germinates as temperatures decrease in fall. Curly-leaf is highly tolerant of cold temperatures and reduced sunlight, continuing to grow under lake ice and snow cover. With ice-off and increasing water temperatures in the spring, the plant produces fruit, flowers, and buds (turions). Turions are the main reproductive mechanism of curly-leaf. To control the species in lakes, the plant must be combated before turions become viable. Most plant harvesters have not started cutting when curly-leaf is most susceptible and a small window of opportunity exists for chemical treatment. Therefore, prevention through public education is once again very important (Hemmingsen and Bunk. Delavan Lake (Walworth County, Wisconsin) Integrated Sensitive Area Report, 01/22/2007). Eurasian water-milfoil and zebra mussels have been documented in lakes Turtle and Delavan. Rusty crayfish have also infiltrated Turtle Lake and curly-leaf pondweed have been found and verified in Delavan Lake. Furthermore, yellow floating hearts were discovered in 2008 in the stormwater retention ponds #1 and #2 in Geneva Landings.

Fish Consumption Advice

Currently, there are no specific fish consumption advisories in effect for the Turtle Creek Watershed. However, a general fish consumption advisory for the potential presence of mercury is in place for all waters of the state.

Date 2011

Groundwater

The following groundwater information is for Walworth and Rock Counties (from Protecting Wisconsin’s Groundwater through Comprehensive Planning website, http://wi.water.usgs.gov/gwcomp/), which roughly approximates to the Turtle Creek Watershed. Clinton, Darien, Elkhorn, Fontana, Sharon, and Williams Bay are the only municipal water systems in the Turtle Creek Watershed that have wellhead protection plans. Sharon also has a wellhead protection ordinance in place. Walworth and Rock Counties have both adopted animal waste management ordinances. From 1979 to 2005, total water use in Walworth County has increased from about 10.0 million gallons per day to 15.3 million gallons per day due to increases in all use categories. The proportion of county water use supplied by groundwater has increased from around 89% to about 99% during the period 1979 to 2005. During the same time period, total water use in Rock County has increased from about 27.2 million gallons per day to about 45.4 million gallons per day. The increase in total water use over this period is due to increases in domestic and irrigation uses. The proportion of county water use supplied by groundwater increased from about 92% to over 99% during the period 1979 to 2005. Private Wells Ninety percent of 340 private well samples collected in Walworth County and 75% of 482 private well samples collected in Rock County from 1990-2006 met the health-based drinking water limit for nitrate-nitrogen. Land use affects nitrate concentrations in groundwater. An analysis of over 35,000 Wisconsin drinking water samples found that drinking water from private wells was three times more likely to be unsafe to drink due to high nitrate in agricultural areas than in forested areas. High nitrate levels were also more common in sandy areas where the soil is more permeable. In Wisconsin’s groundwater, 80% of nitrate inputs originate from manure spreading, agricultural fertilizers, and legume cropping systems. Fonatana and the Village of Clinton have spent money to reduce nitrate levels through the construction of new wells. A 2002 study estimated that 21% of private drinking water wells in the region of Wisconsin that includes Walworth County and 62% of private drinking water wells in the region of Wisconsin that includes Rock County contained a detectable level of an herbicide or herbicide metabolite. Pesticides occur in groundwater more commonly in agricultural regions, but can occur anywhere pesticides are stored or applied. A total of 5,128 acres of land in Walworth County and 18,941 acres of land in Rock County are in atrazine prohibition areas. Over three quarters (76%) of 33 private well samples collected in Walworth County and 100% of 18 private well samples collected in Rock County met the health standard for arsenic. Potential Sources of Contamination There are two Concentrated Animal Feeding Operations (CAFOs) in the Turtle Creek Watershed. These swine CAFOs are located in Elkhorn and Clinton. There are also two licensed landfills in the watershed, which are located in Darien and Beloit. The only Superfund site in the watershed is Delavan Municipal Well No. 4.

In the spring, without such a barrier, carp migrate in great numbers into Mud Lake, creating disturbance to aquatic plants and displacing other fish spawning.

Kettle Moraine Land Trust: Jackson Creek Watershed Protection Plan: The project proposal is for the Kettle Moraine Land Trust to work with the Southeastern Wisconsin Regional Planning Commission to develop a watershed protection plan for Jackson Creek in Walworth County. The goal is to improve the hydrology and water quality throughout the watershed, which will ultimately reduce the suspended solids and nutrients draining to Delevan Lake.

Methods will include identifying strategic actions and interventions such as streambank stabilization, buffer implementation, and wetland restoration. Also, identify relevant agencies and cost, acquire data on channel width, depth, sinuosity, water quality, and discussion on implementing plan recommendations.

Public meeting will be held to inform the public of the project. Educational materials will also be developed to work with and provide assistance to Delavan Lake WIN, municipalities, and landowners within the watershed.

Deliverables will include a watershed protection plan in a SEWRPC Memorandum Report or equivalent document and communication of recommendations to citizens and local municipalities. A $10,000 grant was requested for this project. Total project costs are $15,500.

Monitoring & Projects

Projects including grants, restoration work and studies shown below have occurred in this watershed. Click the links below to read through the text. While these are not an exhaustive list of activities, they provide insight into the management activities happening in this watershed.

Volunteer Monitoring

There have been seven stations monitored by at least 10 Volunteer Stream Monitors in the LR01-Turtle Creek Watershed from 2005 through 2010. Two of the stations are monitored for dissolved oxygen, pH, instantaneous and continuous temperature and transparency using Level 2 procedures, and entered into the SWIMS database http://prodoasjava.dnr.wi.gov/swims/welcome.do. Six stations are monitored for biotic index, flow, dissolved oxygen, instantaneous temperature and transparency using Level 1 procedures, and entered in the WAV database (http://www.uwex.edu/erc/wavdb/). On average, stations in the watershed were monitored monthly from May through October; however Turtle Creek at Heidt Property, CBSM- 10012287 (Level 1 and 2) and Turtle Creek, Creek Rd, Beloit, upstream from Shopiere Rd, CBSM- 10029793 (Level 1) were also monitored during winter months. Volunteers collect macroinvertebrates twice a year (the first and last sampling event of the season) to determine a biotic index for each stream monitored. Streams are considered in poor quality if biotic index is between 1.0-2.0, fair quality if between 2.1-2.5, and in good quality if the index is between 2.6-3.5. Overall, biotic index values rated streams in the watershed to be in fair to good quality (ranging from 2.1-3.5). Stream flow varied depending on season and local weather patterns each year. Volunteers recorded stream flow almost year round at Turtle Creek at Creek Road. Generally, there was a higher flow rate in the spring than late summer and fall throughout the watershed. Average stream flow measurements for the sixty-one field events were 133 cubic feet per second (cfs) and ranged from 36.4 to 368 cfs. Overall, volunteers recorded dissolved oxygen levels in the watershed ranging from 5 -18mg/l, which are sufficient to sustain aquatic life. Throughout the monitoring seasons, volunteers collected pH measurements primarily within state standards (which range from 6 to 9) ranging from 7.37 and 8.35. Temperature measurements, used to classify streams as cold, cool or warm water habitats, and which are indicative of the ability of a habitat to sustain aquatic species were manually and continuously recorded at both stations each season. Maximum instantaneous temperatures were between 26-28°C for all streams using this method; suggesting they may be cool water streams. Maximum daily mean temperatures from the continuously measured temperatures indicate streams transition between cool and warm water throughout the four to five years they were monitored using the data loggers. Stream transparency measurements were erratic throughout the monitoring season with 48% of the 89 field events measuring less than 10 NTU. The remaining 50% of readings ranged from 10-230 NTU. Only one reading at Turtle Creek at Heidt Property measured greater than 240 NTU in June 2009.

Watershed History Note

Turtle Creek originates in Turtle Lake in Walworth County, skirts the City of Delavan, meanders through Rock County and then empties into the Rock River in the City of Beloit. Although Native Americans inhabited this area almost 3000 years ago, it was the Effigy Mound Builders of the Late Woodland Period (500 to 1000 AD), who left their mark upon the land. The Effigy Mound Culture extends from Dubuque, Iowa, north into southeast Minnesota, across southern Wisconsin from the Mississippi to Lake Michigan, and along the Wisconsin-Illinois boundary. Although some mounds are abstract in shape, including the long linear embankments, or dome-shaped mounds, the animal shaped mounds have captured the public's interest. Mounds in the shapes of birds, bear, deer, bison, and lynx have been found. Near Lakes Michigan and Winnebago, turtle and panther mounds are common. Some of the mounds may be up to 150 feet in length. The animal shapes may represent clan symbols or symbolized spirits of the sky, earth and water. The grouping of mounds may indicate social or religious ties among scattered communities. The purpose of the mounds may have been ceremonial or they may have delineated territory for hunting or gathering grounds. Early maps indicate more than 20,000 Indian mounds once existed in Wisconsin; today fewer than 3000 remain. Many of the mounds were built on the high ground overlooking the confluence of the Rock River and Turtle Creek and along the shores of Delavan Lake. Early surveyors of mineral lands and those working for railway were among the earliest Europeans to take notice of these unusual land formations. An article on the Beloit Mound Groups appeared in the November 1919 Bulletin of The Wisconsin Archeologist. This article references research from the mid 1800's and includes maps drawn by researchers from Beloit College which indicate many turtle shaped mounds in the south central part of Wisconsin. The legacy of the Mound Builders lives on today as it is possible that Turtle Creek was named after one of the many turtle shaped mounds found along its banks. The turtle is the unofficial mascot of the college, and Beloit College's Logan Museum of Anthropology houses many of the excavated tools and broken pottery artifacts found in or near the mounds. Today the historical and cultural value of effigy mounds is recognized and they are generally well protected from development for future generations to wonder about and enjoy.
