Christina River Basin High-Flow TMDL Revisions

EPA revised the existing Total Maximum Daily Loads (TMDLs) for the Christina River watershed, which includes Brandywine Creek, Red Clay Creek, and White Clay Creek in Delaware and Pennsylvania. These revisions were made to the Christina River Basin low-flow nutrient/dissolved oxygen TMDLs, high flow nutrient/DO TMDLs, and high-flow bacteria TMDLs, in light of factors such as the availability of recent data and review of the computer model used to develop the original TMDLs.
