12. What Are the Sources of Model My Watershed Data?

Last updated on 2023-07-26

Model My Watershed’s animal data come from the United States Department of Agriculture National Agricultural Statistics Service. 2015 data for each county in the United States was obtained and estimates of animal types per acre of agricultural land were calculated. Animal estimates by type are then apportioned for any given watershed based on the acres of agricultural land (cropland, hay/pasture) in that watershed.

There is a more robust amount of data for the Delaware River Watershed area due to a grant from the William Penn Foundation that allowed us to work with the Delaware River Watershed Initiative’s Stream Reach Assessment Tool for data collection and analysis.

Land coverage data comes from the United States Geological Service. More information can be found in the Model My Watershed Technical Documentation.
