Organizations supporting clean water, rivers, the Chesapeake Bay & Watershed

Clean Water Howard

Howard County’s stormwater management program ensures that stormwater is treated and managed, and also maintains our storm drains, underground pipes, ponds, and streams.


The website has a list of opportunities to get involved and things you can do at home to improve water quality.

Howard County Watershed Stewards Academy

The Howard County Watershed Stewards Academy is a training program to empower residents to improve the water quality of local streams. Stewards become community leaders in reducing harmful effects of polluted stormwater running off into our streams.
