Change Log

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.

27 June 2022 :: Expansion

  • 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.
