Runoff Risk Advisory Forecast Tool Being Developed

The ability to predict the risk of runoff on a particular day can greatly assist Wisconsin producers, manure haulers, and nutrient applicators when making decisions about when to land apply manure or other nutrients. The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP), United States Geological Survey (USGS), National Oceanic and Atmospheric Administration (NOAA), National Weather Service (NWS), National Resources Conservation Service (NRCS), University of Wisconsin (UW), and others are collaborating to develop a risk assessment tool that identifies when there is a high likelihood for surface runoff and, therefore, when to avoid spreading nutrients on agricultural fields.

The Runoff Risk Advisory Forecast map currently shows this assessment of day-to-day runoff risk occurring across Wisconsin using National Weather Service forecast models that consider predicted precipitation, soil moisture, snow melt forecasts and actual individual watershed basin characteristics. However, because all of these conditions can and do vary across a watershed basin, persons intending to apply manure or other nutrients should always apply their knowledge of local conditions when deciding whether or not to spread on a specific field. This tool is a work in progress, continuing to be refined as better weather forecasting data and field runoff information becomes available.

 

The forecast map is updated 3 times each day to account for changes in weather forecasts and soil moisture conditions over short time periods. The forecast tool can be found on the Wisconsin Manure Advisory System website link below.

We need your input to help improve the tool and make it as useful as possible. When visiting the website, please take a few moments to complete the National Weather Service survey, located in the lower right hand portion of the screen, to provide feedback on the forecast’s usefulness to you.
