Water quality in Powers Lake is declining. Water monitoring professionals from the Washington Conservation District (WCD), funded by the South Washington Watershed District (SWWD), have determined that average annual phosphorus concentrations are increasing in the lake. Higher phosphorus concentrations lead to more frequent algae blooms and reduced water clarity.Powers Lake is at risk mainly due to increased urbanization within its watershed (the land area that drains to the lake).
This project will support water quality monitoring and data analysis in nine major watersheds (8-digit Hydrologic Unit Codes) of the Lower Red River Basin. The monitoring will assist in providing water chemistry data needed to calculate annual pollutant loads for the Major Watershed Load Monitoring Program (MWLMP) and provide short term data sets of select parameters to other MPCA programs.
Imminent Health Threat (IHT) systems are those that are discharging improperly treated human waste onto the ground surface or into surface waters. In addition to the potential water quality impacts, untreated sewage has the potential to introduce bacteria and viruses into the environment. When IHT systems are identified, county or city staff assist the homeowners through the process required to bring their systems into compliance with the septic ordinance.
Successful long-term treatment of sewage depends on a system capable of providing adequate treatment and effective on-going operation and maintenance. Clean Water Fund Subsurface Sewage Treatment System (SSTS) Program Enhancement and Inventory funds are used by counties to strengthen programs dedicated to SSTS ordinance management and enforcement. These funds are used for a variety of tasks required to successfully implement a local SSTS program including inventories, enforcement, and databases to insure SSTS maintenance reporting programs.
Stubbs Bay on Lake Minnetonka is impaired for excess nutrients due to phosphorus loading. This impairment results in nuisance algae blooms that limit the recreational use of this water body. As a part of its surface water management planning process, the City of Orono has identified projects to help improve the water quality of Stubbs Bay and Lake Minnetonka. The Stubbs Bay Ravine Stabilization project is one of the projects scheduled for completion in 2011.
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.
This project will provide complementary (same year) physical and chemical data sets for three MPCA prioritized lakes in NE Minnesota to incorporate into the overall State database for MPCA assessment purposes as well as research purposes.
The Upper Minnesota River Water Quality Assessment Project will complete water chemistry assessments of the upper reaches of the Minnesota River Headwaters, which includes the main stem of the river, five main tributaries (Meadowbrook Creek, Salmonsen Creek, Fish Creek, Hoss Creek, Little Minnesota River and Stoney Run Creek), and one flowage lake (Long Tom).
