The Little Gunpowder Falls Watershed is rural in character and forms much of the boundary between eastern Baltimore County and western Harford County. Approximately half of the watershed is located in Baltimore County. The Little Gunpowder Falls watershed begins near the intersection of Troyer Road and Hunter’s Mill Road extending southeast along the Baltimore and Harford County border through the communities of Jacksonville, Sweet Air, Baldwin, Fork, Kingsville, Franklinville and Bradshaw, and emptying into the Gunpowder River upstream of Day’s Cove.

This watershed has large tracts of agricultural land, forested land and a low density of development as compared to most of the other watersheds in Baltimore County. The upper portion of the watershed is predominantly agricultural, and the the lower portion is more developed, including low-density residential, industrial and commercial land use.

Approximately 4,000 acres of this watershed is within Gunpowder Falls State Park, Maryland’s largest state park. The Sweet Air section of the park, located in Baldwin, is a popular destination for picnickers, hikers, horseback riders and mountain bikers.

Small Watershed Action Plan (SWAP)

Small Watershed Action Plans (SWAPs) identify strategies to bring a small watershed into compliance with water quality criteria. Strategies go beyond traditional government capital projects and include actions in partnership with local watershed associations, citizen awareness campaigns and volunteer activities.

A SWAP has been completed for the Little Gunpowder Falls watershed. While parts of this watershed are contained within both counties, this study focuses only on the portion of the watershed within Baltimore County.

  • Volume 1 (PDF) outlines the actions identified as part of the strategy.
  • Volume 2 (PDF) contains the results of the field and geographic information systems data assessments.

Watershed Management Plan

The Little Gunpowder Falls Watershed Water Quality Management Plan was completed in October 2001. The executive summary includes an overview of pollution loads and water quality problems. Management strategies are categorized into public land, developed land and agricultural land strategies. The executive summary (PDF) is available for download.

Volunteer Activities

To participate as a volunteer for the Little Gunpowder Falls watershed, contact the Gunpowder Valley Conservancy (GVC). GVC is the lead agency for the Clear Creeks Project, a citizen-based initiative to restore water quality in the rivers and creeks in focused areas of the greater Gunpowder River basin.
