Runoff Risk Decision Support tools provide farmers and producers actionable guidance about when to avoid short-term nutrient applications due to unfavorable environmental conditions. Runoff Risk tools are based on real-time National Weather Service (NWS) weather and hydrologic models and have been collaboratively developed with many state agencies, universities, and other ag-centric partners in the Great Lakes region.

Runoff Risk is currently available in four states in the Great Lakes region: MI, MN, OH, and WI. Models are available in IL, IN, and NY and therefore tools could be produced in these states if working groups request to collaborate with the National Weather Service. Individual states do need to provide some funding to support their websites and producer training and outreach activities in their areas.
A final round of model enhancement for this version of the Runoff Risk models is currently ongoing with expected implementation in summer 2019.
Continued GLRI support is helping to support the development and transition of Runoff Risk to the newest National Weather Service national-scale modeling framework, the National Water Model. This new framework will provide finer spatial scale guidance more often and enable continuous hydrologic model improvements by universities and agencies that will lead to improved Runoff Risk guidance for farmers and producers. The two-year development project begins in 2019 with a 2-year phase in following that.
