The Sand Hill River Watershed District along with the West Polk Soil and Water Conservation District (SWCD) will install 18 rock riffles and 2 rock arch rapids to control the grade and stabilize the channelized reach of the Sand Hill River, which contributes thousands of tons of sediment downstream. The entire Sand Hill River is currently impaired for turbidity. The total project length is five miles of channel located between the cities of Fertile and Beltrami in western Polk County.
The East Polk Soil and Water Conservation District (SWCD) identified the Sand Hill Watershed as a priority area because of soil loss associated with steep slopes common in the area. The SWCD is working cooperatively with the Sand Hill Watershed District to keep soil from eroding, and to capture it where it does erode. The SWCD provides technical design services and receives funding from the Sand Hill Watershed District to install conservation practice such as sediment basins.
The Sauk River and its seven reservoir lakes are impaired for turbidity, e.coli and excessive nutrients. Local studies conducted on Sauk Lake, the Sauk River Chain of Lakes and the lower reach of the Sauk River identified urban stormwater runoff as a source of sediment and nutrient loading. This project will address stormwater runoff concerns within the communities of Sauk Centre, Cold Spring and St. Cloud by providing treatment through bioretention and infiltration.
There are fifty-seven impaired water bodies in the Sauk River watershed. The goal of this project is to provide the necessary tools for the Sauk River Watershed District (SRWD) and local agencies to work together to target priority areas, install the necessary water quality restoration projects, and track what has been completed to achieve reduction goals for each impaired waterbody. First, technology will be utilized to determine where high priority runoff areas are within the Sauk River watershed. Advanced sub-watershed modeling will be refined to a smaller scale.
The Sauk River's CWMP identifies altered hydrology and excessive sediment & nutrients as the top priority resource concerns to be addressed. Goals for each priority resource concern are found on pages 4-6 and 4-21 of the CWMP. To achieve these goals, The CWMP contains multiple prioritization schemes, on both a watershed-wide and watershed management unit basis, to achieve these goals - refer to pages 4-8 through 4-11 and 4-22 through 4-31 of the CWMP.
The Sauk River Stormwater Runoff Reduction and Riparian Restoration Project is a watershed-wide effort to reduce the amount of nutrients delivered by stormwater and bank erosion to area surface waters. Funds will be used to assist local schools and municipalities with their restoration project design, installation, and financing.
The Sauk River Chain of Lakes Community Partners Area has many lakes that are not meeting state water quality standards or are in jeopardy of not meeting standards and are in desperate need of runoff reduction strategies. The Stearns County Soil and Water Conservation District is eager to work with willing sponsors within the project area to educate, inform and expand the conservation culture to assist in siting and implementing water quality projects on the landscape.
Per the CWMP (pgs. 3-5 through 3-6), the issues Altered Hydrology and Excessive Nutrients and Sediment are top priority issues/concerns to be addressed. During development of this work plan, the Implementation Team added the issue/concern High Water Quality Lakes as a secondary priority for this work plan (13 lakes - CWMP figure 4-9), noting it is closely related, often overlaps, there are multiple benefits to be gained, and there is strong local desire to protect these lakes.
Calcareous fens such as the Savage Fen are fragile ecosystems existing only under a unique combination of soil type, hydrology, chemistry, and vegetation. The City of Savage is continuing efforts to protect this important ecosystem through this project. Two large ravines -Dakota Avenue and McColl's Bluff - discharge to the Fen, which was granted special status under the State's Wetlands Conservation Act. Both ravines are highly eroded and carry a significant amount of stormwater and sediment to the Savage Fen.
The Ramsey-Washington Metro Watershed District (District) has determined that large impervious sites (like churches, commercial sites, and schools) are more economical for stormwater management retrofit projects than distributed small projects along roadways. Analysis of the watershed land use indicates that large impervious sites are typically commercial properties (primarily retail), churches, and schools. The District began assessing church sites for retrofit opportunities in 2013 and will continue this effort in 2014.
Schwanz Lake is an 11.5-acre shallow lake in southeast Eagan that was found to be impaired in 2006 due to excessive levels of phosphorus. The land area draining to the lake is 762 acres, but a small a 28-acre residential neighborhood was found to disproportionately contribute 24 percent (roughly 14 lbs/yr) of the phosphorus, according to a 2010 study of phosphorus sources. The neighborhood was developed before Eagan established water quality requirements for stormwater retention ponds and the neighborhood drains runoff directly to the lake through a single pipe.
The purpose of this project is to install a sediment pond along County Ditch #4A to trap sediment and associated pollutants before entering into Bevens Creek which drains into the Minnesota River. Carver County Ditch #4A recently went through a redetermination of benefits process and state law now requires a buffer strip one rod (16.5 feet) wide to be maintained along the top of the ditch bank. The sediment pond, in combination with the buffer strip, will reduce the amount of sediments and pollutants that reach Bevens Creek.
The Red Clay Project was a 1970's era project that encompassed watersheds in Northeast Minnesota and Northern Wisconsin draining to Lake Superior. In Minnesota, efforts focused on sediment retention structures in two subwatersheds of the Nemadji River Basin in Carlton County. Sixteen structures were constructed in the Skunk Creek Watershed and four structures were constructed in the Deer Creek Watershed. The design life of these structures was 10-25 years depending on the specific project and the design life has now been exceeded.
Seminary Fen, a 600-acre complex in Carver County, supports one of only 500 calcareous fens in the world and is one of the highest quality calcareous fens in southern Minnesota. Given this fact, and the fact that it supports dozens of rare, threatened, and special concern plant and animal species, it has been characterized as one of the most significant natural areas in the Twin Cities Metropolitan Area and is part of the Minnesota Department of Natural Resources Scientific and Natural Areas program.
The Septic Risk Assessment Model and Program Enhancement (SRAMPE) will result in a systematically review and catalog of all septic related materials by licensed SSTS professionals pertaining to the 890 properties in which we believe are served by SSTS. The enhanced program will improve efficiency, customer service, and administrative procedure. Above all, it will lead to upgrading of failing SSTS or conversion to City sewer
Over the past two years, Dakota County has learned that many properties within the city do not have septic system records identifying the presence or condition of their septic system, and anecdotal evidence that some are failing. The County will use CWF Accelerated Implementation Grant dollars to inventory and inspect all septic systems within the City of Randolph. As part of the inspection, a well inventory will also be conducted. Based on a preliminary assessment, there are 105 properties that will require inspection.
Seven Mile Creek is a direct tributary to the Minnesota River in south-central Minnesota. It drains heavily tiled agricultural land in its upper watershed and meanders through a forested valley as a spring-fed trout stream within Nicollet County's premier park.
The weather station portion of the project is to increase the accuracy of weather and road condition data to further refine the Chloride Use/treatment of Shakopee roads. Real-time information from a RWIS station can be used to adjust application settings. Approximately 39 tons (78,000) pounds of salt are used in each event. The city averages 30 events each winter. The City of Eden Prairie has similar weather stations and estimates a 5%-10% reduction in salt use.
This pilot program protected 1,210 acres of wild rice lake shoreland habitat in the Northern Forest Section by securing 14 permanent RIM conservation easements and four fee-title acquisitions, surpassing our goal of 700 acres, and doing so $250,202 under budget.
Shattuck Saint Mary's, located atop of a bluff area upland of the east bank of the Straight River, encompasses a land area of 324 acres that contains over 16,426 miles of mild to extensively eroded ravines and gullies; many of which directly discharge to the Straight River. In addition to pollutant loads in runoff from the school's watershed and eroded ravines, banks and gullies, the Straight River also experiences pollutant loading from eroding stream banks in this reach; annual sediment loads average 1,962 tons per year.
Sherburne County's Local Water Management Plan identifies eutrophication of lakes (heavy algae blooms) caused by excess phosphorus, loss of aquatic vegation, and loss of riparian vegetation. Removal of natural vegetation near the waters edge in developed and agricultural areas has caused loss of fish and wildlife habitat, increased runoff, and allowed bank erosion. The District will address sources of phosphorus and sediment for three important surface waters in the County. In all, phosphorus will be reduced by 355 pounds and sediment will be reduced by 400 tons per year.
The goal of the project is the reduction of nitrates in the groundwater by promoting and implementing best management practices and alternative management tools in the priority areas of Sherburne County. Practices included in the application are: Cover crops, irrigation water management , and nutrient management. Additional incentives included are for the Conservation Reserve Program. District Staff will also plant at least one acre of demonstration plots which will be highlighted at an annual field day.
Forest Lake is one of the top recreational lakes in the metro area and protecting its water quality is a top priority for the Comfort Lake Forest Lake Watershed District. While not currently on the impaired waters list, the water quality of Forest Lake is very near the water quality standard. Shields Lake has been identified as the single largest pollutant contributor to Forest Lake. This project proposes to impound water from a tributary to Shields Lake for golf course irrigation reuse, reducing watershed phosphorus loads to Shields Lake.
Shingle Creek in suburban Hennepin County has experienced significant changes since its days as a narrow, meandering prairie stream. Nearly 100 years ago much of the stream was straightened and dredged to provide better drainage for agriculture. As agriculture gave way to urban and suburban development, Shingle Creek was widened and dredged again to more efficiently convey stormwater to the Mississippi River. Urbanization has resulted in high levels of chloride in the stream from road salt and not enough dissolved oxygen to sustain aquatic life.
The purpose of this project is to create an inventory and priority list of where inlet control and buffer strips are needed along Judicial Ditch 15 to reduce the nutrients, sediment and volume of water being transported by field tile. This will help protect landowner drainage needs, while focusing on applicable best management practices that will reduce on-field and in-channel peak flow erosion. This ditch system is the headwaters to Cokato Lake, which connects to the North Fork Crow River.
The Wright Soil and Water Conservation District (SWCD) will expand its partnership with its USDA partners; this will be the first time that SWCD staff will conduct compliance spot checks for USDA Highly Erodible Land plans. This activity will add a level of certainty that these plans are in compliance.
This project will reduce phosphorus loading from the watershed tributary to Silver Lake. The project includes a combination of structural water quality improvements in the SLV-10 subwatershed north of the lake, retrofits (including iron enhanced sand filtration) to the Silver Lake bioretention basin, small scale best management practices (BMPs) throughout the watershed, and educational signage in Joy Park. The elements of this project will reduce phosphorus loading to Silver Lake by a combined 15 pounds per year or 40% of the current watershed load.
The Chippewa River Watershed Project will work with local partners, such as Land Stewardship Project, soil and water conservation districts, and the Natural Resources Conservation Service, to restore water quality in Lake Gilchrist, Simon Lake, Lake Johanna and in Mud Creek, and to protect unimpaired water resources in the watershed. This will be done through implementation of Best Management Practices focusing on the reduction of phosphorous, sediment, and runoff in the landscape, primarily by increasing the landscape's ability to retain water.
An effective regulatory program is key to the successful implementation of local land use and water management plans. Yet, county, watershed, and other state, tribal, and local agencies charged with enforcement and permit review often work in silos and infrequently coordinate with each other or share information. This leads to higher enforcement costs, conflicts between agencies, redundancy of inspections, property owner frustration, and reinforces negative stereotypes of regulatory agencies.
The Roseau River Watershed District in partnership with the Roseau County SWCD will complete a study to target and prioritize sites contributing impairments within legal drainage systems. Project partners will utilize data developed by the International Water Institute (IWI) Water Quality Decision Support Application that establishes multivariate scoring of each site based on all relevant features contributing to surface water degradation.
The Six Lakes subwatershed analysis will utilize previously completed watershed modeling to conduct subwatershed analyses for six high priority lakes that are closest to meeting state water quality standards or require protection due to high public use and declining water quality trends. This project will develop a long list of cost benefit ranked water quality best management practices based on concept design.
The project is part of the Six Mile-Halsted Bay Subwatershed Plan, a planning partnership currently underway which aims to protect and improve natural resources within this priority subwatershed by working closely with partnering agencies to integrate capital investments and maximize public return on investment. This project will enhance two existing stormwater ponds to enhance treatment of phosphorus as well as incorporate treatment of the Church Lake outlet, a lake which routinely fails to meet state water quality standards and contributes to the water quality impairment of East Auburn.
The Greater Blue Earth River Basin is a large area within the Watonwan, Le Sueur, and Blue Earth River watersheds. Recent research by University of Minnesota, the National Center for Earth Dynamics, and others has found this basin to be the largest contributor of sediment to Lake Pepin.
