Development<br />
This project led to the further development of a<br />
watershed-scale, decision-support tool to facilitate<br />
prioritization and placement of management practices<br />
to achieve the needed reductions identified by various<br />
watershed management programs in Minnesota. The<br />
decision-support tool, SAM, now consists of a GIS system<br />
for site selection, HSPF model application to simulate<br />
the transport and fate of pollutants, and development<br />
of a set of management practices and HSPF Parameters<br />
associated to those practices. This decision support<br />
tool provides decision makers with a user friendly,<br />
comprehensive approach to achieve the water quality<br />
improvement goals set by the TMDL assessments,<br />
protection strategies, and watershed restoration<br />
programs. The decision-support tool assists in identifying<br />
priority areas and BMPs that will provide the greatest<br />
water-quality benefits for dollar invested.<br />
The value of the tool is in its simplification of complex<br />
hydrologic and water quality models into a transparent<br />
estimation of the significant pollutant sources in<br />
watershed. Local watershed entities can then apply their<br />
knowledge and expertise of BMP implementation using<br />
the tools interpretation of model results.<br />
Goals<br />
• The review and selection of an existing HSPF model to<br />
serve at the SAM pilot. (Yellow Medicine River).<br />
• Develop a list of management practices appropriate to<br />
the Yellow Medicine River watershed.<br />
• Construct the SAM interface.<br />
Results that count<br />
• The Yellow Medicine River watershed was selected to<br />
serve as the SAM pilot watershed.<br />
• With input from local partners, a list of relevant BMPs<br />
were chosen for inclusion in the SAM tool.<br />
• The SAM interface was constructed using the existing<br />
Yellow Medicine HSPF model as a foundation.<br />
• Intensive monitoring revealed extensive influence<br />
from Upper Prior Lake on the southernmost bay,<br />
and influence from the watershed on the rest of<br />
the lake. Further communication will build on this<br />
understanding of what influence BMPs will have on<br />
different parts of the lake.<br />
