Watersheds

Winters Run, a part of the Bush River river basin.

There are 13 watersheds in Harford County. A watershed is comprised of the hills and valleys that drain into a single river, stream, or lake. These smaller tributaries then drain into 4 major river basins: the Bush River, Gunpowder River, Lower Susquehanna River, and the Upper Western Shore. 

In turn, all of the waterways in Harford County, from small farm streams to the whitewater of the Gunpowder, ultimately drain into the Chesapeake Bay.

Stormwater Control

Harford County has a Stormwater Management Division, responsible for monitoring stormwater controls at new developments.

Harford County follows the Maryland Department of Environment Stormwater Design Manual for best management practices at new developments and construction sites,  but has few other measures in place to address stormwater pollution.

The County’s stormwater remediation fee was repealed in 2015. The fee was intended to fund needed maintenance and improvements to existing stormwater management facilities and to reduce erosion and the flow of polluted runoff into local streams and the Chesapeake Bay.

Without this fee to correct existing problems, the money must be taken from other parts of the budget. The lack of funds also means the projects will take a very long time to complete, during which time the damage to public and private property will continue.

Loss of wetlands and uncontrolled stormwater runoff contribute to flooding in Harford County.

Wetlands

Wetlands perform essential ecological functions for our community. They provide habitat, filter pollutants, absorb water and reduce flooding. Wetlands are especially important in Harford County because our waterways directly affect the health and water quality of the Chesapeake Bay.

FOH position paper on Bill 16-002 affecting wetlands & Natural Resource Districts. The bill passed and became law in March 2016.  As a result, non-tidal wetlands less than 40,000 square feet in size (about 1 acre) are no longer considered Natural Resource Districts and can be disturbed or altered by development.
