The primary goal of this project is to analyze of dated sediment cores to reconstruct changes in the lake condition over the last 150 years. This will be done using multiple lines of evidence including biogeochemistry, sediment accumulation, and diatom and algal remains as biological indicators.
This project will provide notification of the potential for coal tar contamination, establish a storm water pond inventory schedule, and develop best management practices for treating and cleaning up contaminated sediments. The sampling design includes 15 stormwater ponds, 5 each from residential, commercial, and industrial land use areas. Municipalities in the metro area with MS4 permits of stormwater ponds will be contacted to nominate candidate sites for this study. GPS coordinates will be taken at all sampling sites.

This project will evaluate and prioritize approximately 13,000 lineal feet of Lake Koronis shoreline for shoreline erosion and vegetative buffer condition. Those property owners with the most erosion, stormwater and vegetative buffer issues will be targeted to stabilize, infiltrate and buffer their shoreline. This project will also evaluate an additional 300 properties in the subcatchment area and target those properties that are best able to capture and treat stormwater from impervious surfaces.
The Minnesota Pollution Control Agency (MPCA) has identified streamflow alteration as a key stressor on aquatic life, but the characteristics of streamflow alteration acting as stressors have not been identified in the MPCA Watershed Restoration and Protection Strategy (WRAPS) process. Without indices that characterize streamflow alteration, the MPCA cannot quantitatively associate metrics of aquatic life condition to streamflow alteration. The lack of quantifiable indices limits the ability of the MPCA to assess environmental streamflow needs for streams and rivers throughout Minnesota.
This project will quantify and qualify the effectiveness of herbicide treatments and native plant re-establishment at Duck Lake through systematic vegetative surveys pre and post herbicide application and following mid-summer die-off of curly-leaf pondweed. The data and analysis will ultimately be used in the development of TMDLs, implementation and protection strategies for other lakes in the Middle Minnesota Major Watershed.
Ballast water - water carried in tanks on ships to help provide stability and aid steering - is likely the single greatest source for introduction of non-native and invasive aquatic species. Ballast water is collected in one body of water and discharged into another body of water, usually large distances apart. At least one new invasive species is found in the Great Lakes every year, with Lake Superior being particularly at risk. Scientists from the U.S.

Groundwater sample collection and analysis will be conducted for contaminants of emerging concern (CEC) at large subsurface treatment systems (LSTS) and rapid infiltration basins (RIB), using an enzyme linked immunosorbent assay (ELISA) methodology. Results from the ELISA analysis will be reported to the Minnesota Pollution Control Agency (MPCA) and used to conduct follow-up investigations at a select number of these sites.
Concern for Deer Yard and Poplar lakes centers on their current trends of decreasing water transparencies often associated with phosphorus or sediment increases. Although both lakes still meet nutrient goals, trends in Secchi depth may presage emerging issues with the state of the lakes. This has further led to questions whether the productivity of the lakes have changed over time, what the natural or historical condition of the lakes were, what the current trajectory of each lake is, and how to best set management goals.
This project will complete a Acetochlor Impairment Response Report. This report will combine and coordinate information relating to actions being done in direct response to the acetochlor water quality impairments with those being done and support MDA’s on-going responsibility to assure pesticides are used in a manner that does not cause unreasonable adverse effects on the environment.
The Little Fork River and Big Fork River - USGS FLOWSED project was established to collect site specific data for streamflow, SSC, and bedload at the Littlefork and Big Fork Rivers in Northern Minnesota; use the data to evaluate the use of dimensionless sediment rating curves for the rivers; and document the results of the study in conjunction with the results from other rivers in the state for the application of regional sediment rating curves to rivers in Minnesota.

The Statewide Sediment Network was established to measure the levels of suspended sediment concentrations and particle size distributions at eight sites across Minnesota to evaluate the amount of sediment carried by rivers. USGS sample collection and laboratory analysis techniques provide a more rigorous, robust, and technically accurate measure of sediment in water than the current use of total suspended solids as the measure of sediment in water.
This project will conduct on-going sampling and lab analysis for suspended sediment concentration at select sites. It will also develop real-time continuous suspended sediment concentration measurements using turbidity and Acoustic Doppler Velocity Meter sensors, data analysis and draft United States Geological Survey (USGS) Scientific Investigations Report, and comparison of sampling and laboratory methods for total suspended solids and suspended sediment concentrations.
This project will result in updates to existing information and incorporation of new information into the Minnesota Stormwater Manual. The information is used by stormwater practitioners to implement the most effective and cost-efficient practices for managing stormwater runoff volume and pollutants, in addition to meeting regulatory requirement associated with stormwater permits.
This project will result in updates to existing information and incorporation of new information on active construction site erosion prevention and sediment control into the Minnesota Stormwater Manual. The information is used by stormwater practitioners to implement the most effective and cost-efficient practices for managing stormwater runoff volume and pollutants, and to meet regulatory requirements associated with stormwater permits.
This project will apply the Sunrise River watershed computer model generated under previous projects to selected scenarios of land-cover and land-management changes. The watershed model calibrated to conditions in the late 1990s will form the initial baseline against which all other model runs will be contrasted. Scenarios to be run will include changes in future land cover, agricultural practices, urban practices, and natural resource management.

The MPCA is undertaking a study to investigate the potential effects of elevated sulfate on the growth of wild rice. One high-priority hypothesis is that the conversion of sulfate to sulfide in anoxic subsurface sediment may harm the roots of wild rice, either directly, or indirectly. The goal of this project is To observe and develop an understanding of exposure of wild rice roots to changes in concentration of sulfide and related chemicals over time and space (depth of sediment and distance from roots).
