ChesapeakeStatChesapeake Bay Watershed Implementation Plan
Delaware is among six Chesapeake Bay Watershed states – along with Maryland, Virginia, West Virginia, Pennsylvania, and New York – and the District of Columbia committed to a federal-state initiative to develop a pollution “diet” that will help restore the water quality of the Bay and its tidal waters by 2025.

Properly installed and functioning practices and technologies reduce local flooding, protect sources of drinking water, ensure against the collapse of stream banks, andWatershed Plans and Strategies
Numerous documents describing plans or strategies for water quality and watershed improvements have been developed over the years. Some of these efforts originated through the Tributary Action Team process while others came through other initiatives. All of the documents below can be considered watershed management plans for the Water Quality Improvement Projects grant programPollution Control Strategies and Tributary Action Teams
A 1997 federal court case required Delaware to set pollution limits for its waterways. These limits are called Total Maximum Daily Loads or TMDLs, a term you will hear a lot in water pollution discussions. In order to meet these new pollution limits, we are identifying ways to reduce water pollution. Usually, citizens don’tTotal Maximum Daily Loads
When monitoring reveals that waterways do not meet Delaware’s water quality standards, they are reported on a list of impaired waterways (303(d) List). For each impaired waterway, the Federal Clean Water Act (CWA) requires states to develop Total Maximum Daily Loads (TMDLs) for the pollutants of concern. A TMDL sets a limit on the amountIntegrated Report: 305(b) Report and 303(d) List
