Sum of all watershed-based (HU-8) implementation interests or priorities identified as of June 2016 within the Mississippi River Basin. These watersheds represent areas identified as a focus for investment to improve either water quality or aquatic habitat. Data was compiled from state, federal, regional, and non-governmental organizations including, but not limited to USDA-NRCS, USEPA, USFWS, Fish Habitat Partnerships, Gulf Hypoxia Task Force, and State Nutrient Reduction Strategies. Some HUC-12 priority watersheds were included as well, but coded to the HUC-8 level. Data from the Mississippi River Basin Initiative, National Water Quality Initiative and State Nutrient Reduction Strategies were updated in 2016.
