EPA and USGS Release Report on Aquatic Life and Hydrologic Alteration - EPA and the U.S. Geological Survey (USGS) released a report providing scientific and technical information related to protection of aquatic life from effects of hydrologic alteration. This non-regulatory report presents a literature review of natural flow and a description of the potential effects of flow alteration on aquatic life, as well as examples of water quality criteria that some states have developed to support natural flow and maintain healthy aquatic life. The report also describes a flexible technical and scientific framework that state water managers can consider if they are interested in developing narrative or numeric targets for flow that are protective of aquatic life.
SWC Launches Nutrient Reduction Success Resources - This week, the Source Water Collaborative launched a series of resources around the theme of nutrient reduction successes, including blogposts from EPA and ASDWA, an interactive Story Map highlighting nutrient reduction successes nationwide, links to resources such as the SWC’s Agricultural Collaboration Toolkit, and SWC’s recent webinar on messaging source water protection in agricultural communities.
