Minnesota River Basin <strong>Watershed</strong> <strong>Achievements</strong> <strong>Report</strong> 2015<br />
Project involving multiple watersheds<br />
HSPF Minnesota River basin<br />
resegmentation 2010-2012<br />
This project resulted in the successful temporal extension<br />
of the simulation period through the year 2012, resegmentation<br />
and recalibration and validation of the<br />
Chippewa and Hawk Creek-Yellow Medicine HSPF<br />
models. These fully functioning calibrated and validated<br />
executable models simulate hydrology, sediment (sand,<br />
silt, and clay), temperature, phosphorus, nitrogen, DO,<br />
BOD, and algae at the 12-digit HUC subbasin scale (or<br />
finer) within the specifications formulated by AquaTerra<br />
Consultants for the EPA. Additionally, these models were<br />
reconnected to the Middle Minnesota River watershed<br />
HSPF model. The Chippewa River, Hawk Creek, Yellow<br />
Medicine River, Redwood River, Cottonwood River,<br />
Watonwan River, Le Sueur River, and Blue Earth<br />
River watersheds are all connected to the Middle<br />
Minnesota River watershed and subsequently<br />
the Lower Minnesota River watershed models.<br />
These connections recreate a basin-wide HSPF<br />
model for the Minnesota River Basin.<br />
Goals<br />
• Extend the simulation period of the Chippewa<br />
River, Yellow Medicine River and Hawk Creek<br />
watersheds through 2012.<br />
• Reconnect the models with the Middle<br />
Minnesota River HSPF model.<br />
• Reestablish a seamlessly executable linked<br />
Minnesota River Basin model.<br />
Results that count<br />
• The Yellow Medicine River, Chippewa River<br />
and Hawk Creek watershed models now run<br />
through the year 2012.<br />
• Outputs from the Yellow Medicine River,<br />
Chippewa River and Hawk Creek watershed<br />
models are now read as inputs by the Middle<br />
Minnesota HSPF models.<br />
• A Minnesota River Basin HSPF model has been<br />
reestablished. Ten HUC 8 models can be run in<br />
sequence to model the entire Minnesota River<br />
Basin.<br />
