The Daily Erosion Project (DEP) is continually refining its processing and updating input databases.  With each update, the entire archive is reprocessed with the data updated for the 2007-yesterday period.  This page documents the changes made to the DEP database.

• 1458 new HUC12s were added in Nebraska. As when we add other areas, it will take a few days for the results to settle down.  This area also features our first foray into prescribed irrigation. 

7 June 2022 :: Expansion

• 147 new HUC12s were added from the Minnesota Headwaters region and around Green Bay.  Please give the results from this area a few days for reprocessing to complete.
