4.1.5 Hydrologic Data Program

The Minnehaha Creek Watershed District’s (MCWD) annual Hydrologic Data Program is designed for the collection of background water quality and quantity data. The program is a collaborative effort between the Three Rivers Park District (TRPD), the Minneapolis Park and Recreation Board (MPRB), the Metropolitan Council (Met Council), the Minnesota Pollution Control Agency (MPCA), the Lake Minnetonka Conservation District (LMCD), and the Minnesota Department of Natural Resources (DNR). Data collected is used to identify water quality trends, track progress, and analyze water related problems. The program began in 1968. The District undertook an expanded monitoring program in 1997 to provide a comprehensive view of water quality and to focus improvement projects in the areas with the most need.

The annual program includes precipitation monitoring; lake water quality and lake level monitoring; streamflow and stream water quality monitoring; and groundwater well level tracking.  Lake and stream data are summarized on easy to understand Report Cards for the general public, while the complete report is published annually.  Data is uploaded to the national water quality database STORET where it is available for public use.

The Hydrologic Data Program also includes special studies undertaken by the District including lake bottom core sampling and diatom analysis.
