Appendix C-3 Deer Creek Watershed Conservation and Restoration Seymour (continued from page 3) Says Streamside buffers, also called riparian buffers, are essential in maintaining cleaner, healthier water- ways, controlling erosion and flooding, and in creat- ing and maintaining fish and wildlife habitat. Owners of properties identified in the WRAS as having in- adequate buffers, along with properties already in the Rural Legacy program, were recently sent letters informing them of the benefits of forested streamside buffers. Other properties with inadequate forested streamside buffers located within priority subwater- sheds of Deer Creek are being identified through the use of GIS and aerial photographs and will also be contacted via letters later this year. Money from the $400,000 grant is available to design plans to estab- lish streamside buffers.

Plumtree Run Watershed
Plumtree Run at Tollgate Road Stream Restoration
The stream restoration project adjacent to 1512 S. Tollgate Road is now under construction (across from the BelAir Veterinary Hospital 1501 S. Tollgate Road). You can park at Tollgate Road and Ruth Avenue and walk to the site. Please be careful walking on Tollgate Road. You are advised to wear a safety vest or reflective clothing if possible. PLEASE DO NOT ENTER THE CONSTRUCTION SITE.
Introduction
The Plumtree Run Watershed is located in Harford County in the northeast-central section of Maryland, known as "Bel Air". The total watershed area at its confluence with the Atkisson Reservoir is 1,651 acres.
The study area includes Plumtree Run and its tributaries from their headwaters upstream of Route 1 and Route 24 to the confluence with Atkisson Reservoir. A total of 8.84 miles (46,674 linear feet) of Plumtree Run and its tributaries were reconnoitered and mapped.
Contact Information The Plumtree Run watershed shows evidence of increased sedimentation due to construction activities, stream channel erosion in response to increased storm water runoff, and an overall increase Deborah Lewis in pollutant loadings due to the conversion from forest and cultivated land to residential and [email protected] commercial land uses. Over the last four decades, the water quality has degraded, flood storage (410) 638.3545 x1059 capacities have been reduced, and public infrastructure as well as public and private land along the Christine Buckley, P.E. County's stream corridor have damaged significantly. The contribution of unmanaged stormwater [email protected] runoff and unstable headwater streams make to sedimentation, and water quality declines in the (410) 638.3545 x1176 Atkisson Reservoir (large open water habitat located immediately downstream of the Plumtree Run Watershed).
Harford County Department of Public Works, Water Resources Engineering has prepared Watershed Harford County's Website Management Plans focused on identifying water quality problems and developed strategies for correcting these problems. These programs include installation of new water quality best management http://www.harfordcountymd.gov/dpw/ practices (BMPs), rehabilitation of old storm drain systems, installation and retrofitting storm water engineering/waterresources management ponds, and implementation of stream restoration projects. It is the intention of the Harford County Department of Public Works, Water Resources Engineering to control runoff from the developed areas, correct stream channel instability problems, reduce sediment loading, and improve the overall water quality of Plumtree Run and the Atkisson Reservoir.

A total of 8.84 miles (46,674 linear feet) of Plumtree Run and its tributaries were reconnoitered and mapped.
Assessment Methodology Stream Segments
To facilitate the field work and evaluation Plumtree Run and its tributaries were divided into four separate stream segments.
The segments include: 1) Upper Plumtree Run 2) Upper Middle Plumtree Run 3) Lower Middle Plumtree Run 4) Lower Plumtree Run

Plumtree Run Watershed
The Plumtree Run Watershed Assessment Findings (Final) Report can be viewed online. Instuctions to view the report can be found below.
Introduction
The Plumtree Run Watershed is located in Harford County in the northeast-central section of Maryland, known as "Bel Air". The total watershed area at its confluence with the Atkisson Reservoir is 1,651 acres.
The study area includes Plumtree Run and its tributaries from their headwaters upstream of Route 1 and Route 24 to the confluence with Atkisson Reservoir. A total of 8.84 miles (46,674 linear feet) of Plumtree Run and its tributaries were reconnoitered and mapped.
Contact Information The Plumtree Run watershed shows evidence of increased sedimentation due to construction activities, stream channel erosion in response to increased storm water runoff, and an overall increase Deborah Lewis in pollutant loadings due to the conversion from forest and cultivated land to residential and [email protected] commercial land uses. Over the last four decades, the water quality has degraded, flood storage (410) 638.3545 x1059 capacities have been reduced, and public infrastructure as well as public and private land along the Christine Buckley, P.E. County's stream corridor have damaged significantly. The contribution of unmanaged stormwater [email protected] runoff and unstable headwater streams make to sedimentation, and water quality declines in the (410) 638.3545 x1176 Atkisson Reservoir (large open water habitat located immediately downstream of the Plumtree Run Watershed).
Harford County Department of Public Works, Water Resources Engineering has prepared Watershed Harford County's Website Management Plans focused on identifying water quality problems and developed strategies for correcting these problems. These programs include installation of new water quality best management http://www.harfordcountymd.gov/dpw/ practices (BMPs), rehabilitation of old storm drain systems, installation and retrofitting storm water engineering/waterresources management ponds, and implementation of stream restoration projects. It is the intention of the Harford County Department of Public Works, Water Resources Engineering to control runoff from the developed areas, correct stream channel instability problems, reduce sediment loading, and improve the overall water quality of Plumtree Run and the Atkisson Reservoir.
