The goal of this work order is to collect and process the watershed specific files needed to create the Scenario Application Manager (SAM) project files to apply the SAM software in selected major watersheds in Minnesota where an Hydrological Simulation Program – FORTRAN (HSPF) model has been developed. This work order will also involve technical support for the SAM users who are applying the SAM projects.
The goal of this work order is to enhance the Scenario Analysis Manager (SAM) support tool in order to represent best management practices in a more physically based manner, improve point scenario representation and analysis, and support MPCA with training in the application of the enhanced functionality.
The contractor will provide 3 Scenario Analysis Manager (SAM) training sessions in the fall of 2016 for use with Hydrological Simulation Program FORTRAN (HSPF) model applications.
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.
This project will provide lake and stream monitoring assistance to the Minnesota Pollution Control Agency (MPCA), identifying impaired waters within the Lower Minnesota RIver Watershed (Watershed ID: 07020012) according to the Intensive Watershed Monitoring (IWM) Approach.
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.

The project will develop a web application that provides suspended sediment concentration, sediment bedload, and annual total sediment load estimates to characterize the sediment load to Minnesota's rivers. This will be accomplished using a machine learning model developed from previously collected data. The results will help Minnesota Pollution Control Agency (MPCA) staff evaluate Hydrological Simulation Program – FORTRAN (HSPF) models and will assist in stressor identification.
This project will create and add a sediment component in the Stream Stats Program for Minnesota. This tool will be used by Minnesota Pollution Control Agency Wwtershed program staff and local partners to estimate sediment inputs in stream networks statewide.
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.
The goal of this project is the continued development of an overall strategy for reduction of turbidity/TSS, with sets of sediment reduction initiatives and actions for various sources, to address the Minnesota River Turbidity TMDL and the South Metro Mississippi River TSS TMDL. The overall strategy will be used to help establish a path towards achieving the required reductions of turbidity/TSS.
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 goal of this project is to use the Watershed Data Integration Program (WDIP) Project to apply previous experience with business analysis to the MPCA’s efforts. Develop and document implications for the strategic approach of the business to Watershed projects, their communication and implementation plans to shift to the new strategy, and the daily processes of the business that will be required to change.
The goal of this project is to provide drilling services for the Sentinel Lakes Groundwater/Surface Water Interaction Network. The three new wells will be used for monitoring the interaction between groundwater and surface water in Lakes Shaokatan and Bear Head. Groundwater/lake water interactions are not well understood, and in order to produce accurate and useful Total Maximum Daily Load watershed investigations and impairment remediations, the MPCA must understand how groundwater affects lake water quality.
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 Seven Mile Creek Condition Monitoring project will maintain and build on the continuous flow and water quality data base at three stream sites and one county tile in the Seven Mile Creek watershed through the collection of approximately eighty five water samples per monitoring season in preparation for the Middle Minnesota Intensive Watershed Monitoring scheduled to begin in 2013.
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.
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.
This project will complete an extension of the Shell Rock River Hydrologic Simulation Program FORTRAN (HSPF) watershed model application through the year 2018. Compliance scenarios will be executed to address potential expansion of discharges from the Albert Lea Wastewater Treatment Plant (WWTP).
This project is for surface water assessment in the Shell Rock and Winnebago River Watershed including four stream sites and two lake sites. Waters of concern include Lime creek, Bancroft creek, Goose creek, a tributary to Fountain Lake, Albert Lea Lake and State Line Lake. The outcomes includes establishing baseline data for the associated sample site.
Run a set of scenarios in Hydrological Simulation Program – Fortran Scenario Application Manager (HSPF-SAM) for the Shell Rock and Winnebago River Watersheds. The scenario results will identify the most cost-effective subwatersheds and higher resolution areas based on the terrain component for the scenario best management practices (BMPs) to be implemented. The terrain analyses redistributes subbasin-wide SAM loading rates at a higher resolution for localized targeting of more critical and cost-effective source areas.
The goal of this project is to leverage the existing Hydrological Simulation Program FORTRAN (HSPF) model application that has been calibrated and validated for the Shell Rock River Watershed to assist with wastewater permitting. The contractor will deliver all modeling files and a final technical memorandum outlining the scenarios developed, how the scenarios are represented in the model, and the impact these scenarios have on water quality at specified locations for parameters of concern as described below.
The project consists of two initiatives: soil health outreach and a street sweeping study. These two initiatives will support further prioritization and targeting for nutrient reduction in the watersheds. The goal of this project is to increase implementation of soil health practices across the watersheds and adjust street sweeping schedules to reduce stormwater nutrient loading to surface waters.
RESPEC will address comments on the Shell Rock Total Maximum Daily Load (TMDL) document. The outcome of this project will be a Shell Rock River Total Maximum Daily Load (TMDL) report that is updated to reflect comments from the Minnesota Pollution Control Agency (MPCA), Environmental Protection Agency (EPA), the general public, and other stakeholders.
This project will conduct the second round of Intensive Watershed Monitoring (IWM) for the Mississippi River St. Cloud watershed. Partnering organizations intend to complete sampling of lakes and streams following the protocols and guidance set forth by the Minnesota Pollution Control Agency (MPCA). Watershed partners include Benton Soil and Water Conservation District (SWCD), Clearwater Watershed District, Sherburne SWCD, Stearns SWCD, Stearns County staff, and Wright SWCD.
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 proposed project area covers roughly one hundred square miles within Sibley County, but also includes a small portion of Nicollet County where Judicial Ditch 1A runs into the south branch of the Rush River. One lake and seven streams are part of the proposed project monitoring sites. Of the seven stream locations, two are part of the High Island Creek Watershed, while the remaining five are part of the Rush River Watershed. The lone lake, Lake Washington, falls within the Bevens Creek Watershed.
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.
