Watershed Tools
IWI applied research produces tools that contribute to the improvement of water and soil resources. All tools below are available for public use.
IWI Mapping Portal
The IWI mapping portal was estblished in 2005 with funding from the North Dakota Red River Joint Water Resource District and the Minnesota Red River Watershed Management Board.
The portal provides public access to geospatial data available for the Red River of the North Basin. It includes tools to measure distances, obtain spot elevations, generate cross-sections, and depict historic flood inundation levels. A powerful Watershed Delineation and Hydrology Report tool was added as part of the ND Prioritize, Target, and Measure Application (PTMApp). Users can interactively delineate and download watershed boundaries as geospatial datasets and generate watershed hydrology reports.
Canfield Bachman Lake Water Quality Model
This tool predicts lake total Phosphorus based on a model developed and tested using data on 704 natural and artificial lakes, including 626 lakes in the U.S. Environmental Protection Agency (EPA) National Eutrophication Survey. The model yields unbiased estimates of Phosphorus concentrations over a wide range of lake types. The 95% confidence interval is 31-288% of the calculated total Phosphorus concentration.
OPEN MODELStewardship Program
The Stewardship Program (SP) helps agricultural producers model agronomic risk and realize soil and nutrient retention.
The SP Wayfindr software application allows producers to easily explore how current and potential farm operations affect their fields’ soil and nutrient loss, profitability, and yield. Farmers select any combination of modifications to tillage, crop rotation, fertilizer application methods, and conservation practices for a particular field or a collection of fields. Wayfindr generates a Stewardship Rating based on quantitative water, soil, and nutrient metrics.
Wayfindr can serve as official record for producers wanting to document their agricultural practices for tax credits, commodities markets, and positive impacts on soil and water.
