The DNR is working with local communities and an interagency team to define, prioritize, and establish groundwater management areas in Minnesota. Groundwater management areas will have increased data collection and monitoring that allow the state and local communities to understand water supplies, uses, limitations, and threats to natural resources that depend on groundwater. This information will support detailed aquifer protection plans that ensure equitable and sustainable groundwater and drinking water use for the future.
The Discovery Farms program is a farmer-led effort to gather information on soil and nutrient loss on farms in different settings across Minnesota. The mission of Discovery Farms Minnesota is to gather water quality information under real-world conditions.
The DNR works with the Minnesota Pollution Control Agency and the Minnesota Department of Health to determine the level of contamination from mercury and other harmful chemicals in fish from Minnesota's lakes and rivers and to track the success of efforts to reduce mercury pollution. Clean Water Legacy funding is being used to significantly increase (more than double) the number of lakes and rivers that are assessed for mercury contamination on an annual basis. Fish are collected during DNR fishery surveys, processed for laboratory testing, and analyzed for contaminants.
The Minnesota DNR and the Minnesota Forest Resources Council work with forest landowners, managers and loggers to implement a set of voluntary sustainable forest management guidelines that include water quality best management practices (BMPs) to ensure sustainable habitat, clean water, and productive forest soils, all contributing to healthy watersheds. This project will monitor the implementation of these forest management guidelines and BMPs on forested watersheds in MN.
The Index of Biological Integrity (IBI) is a tool that can identify water pollution problems based on how the type and abundance of certain species in a biological community vary from expected conditions. The Minnesota Pollution Control Agency currently uses IBIs for fish and macroinvertebrates (stream-dwelling insects and other critters) to help determine whether streams and rivers are impacted by water pollution.
This project will establish a groundwater monitoring network in the 11 county metropolitan area. The network will provide information about aquifer characteristics and natural water trends by monitoring healthy aquifers (non-stressed systems). The project will also develop an automated system that captures groundwater level and water use data. This system will enhance evaluation of changes in aquifers that are stressed by pumping from existing wells.
Myrtle Lake experiences frequent nuisance algae blooms and does not meet Minnesota state standards for total phosphorus and chlorophyll-a. This has led to questions whether the productivity and condition of the lake has changed over time, what the natural or historical condition of the lake was, what the current trajectory of the lake is, and how to set effective management goals.
The purpose of the Minnesota Department of Agriculture's monitoring activities is to determine the presence and concentration of pesticides in Minnesota's groundwater and surface water. Monitoring information is used to characterize and assess the extent of pesticide impacts to Minnesota's water resources.
Stream flow information is essential for understanding the state of Minnesota's waters. Clean water funding has allowed the DNR to expand a network of stream gages that support planning and implementation for clean water protection and restoration. These gages are also used as part of the interagency Flood Forecasting/Warning System.
The purpose of this project is to gather data specific to developing a site-specific standard for phosphorus for Upper and Lower Red Lakes. These are large shallow lakes that are located in an area where no shallow lake standard exists. Because of these lakes' unique characteristics, it is believed that a site-specific standard is more appropriate than the deep lake standards that currently exist. This project will include additional chemistry and flow monitoring of tributaries to the lakes, as well as outflow of Lower Red Lake to the Red Lake River.
The Watershed Health Assessment Framework is a web-based tool for resource managers and others interested in the ecological health of Minnesota’s watersheds. The framework uses five ecological components to organize and deliver information about watershed health conditions in Minnesota. The five components are: hydrology, connectivity, biology, geomorphology, and water quality. The WHAF website strives to make complex issues easier to visualize. An interactive map delivers 27 health scores organized by the five components.
