The DNR works with the Minnesota Geological Survey (MGS) to convey valuable geologic and groundwater information and interpretations to government units at all levels, but particularly to local governments, private organizations and citizens.
This project will improve our understanding of the sources of sediment (turbidity), and the processes which deliver sediment to river channels. This project will address a suite of emerging questions regarding contributions and causes of non-field sediment, thereby providing watershed managers with a better understanding of how to manage these sediment sources.
This project will create a high accuracy elevation dataset - critical for effectively planning and implementing water quality projects - for the state of Minnesota using LiDAR (Light Detection and Ranging) and geospatial mapping technologies. Although some areas of the state have been mapped previously, many counties remain unmapped or have insufficient or inadequate data. This multi-year project, to be completed in 2012, is a collaborative effort of Minnesota's Digital Elevation Committee and partners with county surveyors to ensure accuracy with ground-truthing.
This project supports monitoring and assessment activities by MPCA EAO staff and includes lab analysis, equipment, and fieldwork expenses associated with monitoring and assessment activities.The ambient groundwater monitoring network describes the current condition and trends in Minnesota's groundwater quality.
The Minnesota Pollution Control Agency (MPCA) uses a watershed-oriented approach to assess surface water quality and define restoration and protection measures. Each of Minnesota’s 81 major watersheds is assessed intensively every 10 years, based on a staggered schedule that addresses, on average, eight watersheds per year. To increase the amount of data directly available to the public online, and to make internal operations more efficient, the MPCA started a multi-year Watershed Data Integration Project (WDIP).
This project will support the MPCA’s water quality monitoring and assessment program. Specifically, the MPCA is developing a refined use designation process known as tiered aquatic life uses (TALU) to account for situations in which stream habitat has been compromised through hydrological alteration (e.g. channelization and ditching). An accurate state-wide determination of altered stream segments based upon the current National Hydrography Dataset (NHD) linework will assist in the assignment of the correct beneficial use within this new TALU framework.
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.
This project delineates and maps watersheds (drainage areas) of lakes, rivers, streams, and wetlands for the state of Minnesota and provides watershed maps in digital form for use in geographic information systems. These maps become the basis for clean water planning and implementation efforts.
