Water Quality improvement projects

Some of our water quality improvement projects, including total maximum daily loads (TMDLs), are active and have webpages that are listed alphabetically (see left navigation menu). However, to find all of our improvement projects consult the directory of projects organized by county

Water quality projects directory

Read reports on improvement projects

Each listing in the water quality projects directory gives general information on a water body, what pollutants are being dealt with, status of the project, and contact information in case you have questions.

If more information is available about a project, it will be hyperlinked to the water body name. Use our Water Quality Assessment Query Tool to get data about water bodies.

To see all of our water quality improvement reports, see the Water Cleanup Plans in our publications database (listed by year).
