Topo map of watershed

Below is a topographic map of Sally Ormsby Park and Accotink Creek.  The area within the red ink is the study area.

The sticky note at the top of the map denotes the elevation of 270 feet where Accotink Creek enters Sally Ormsby Park. The sticky note at the bottom of the map denotes the elevation of 260 feet where the creek leaves the park.  So, there is only a 10 feet elevation loss in the park.  About a 100 yards northwest on the Cross County Trail from eastern boundary of the park, there is a footbridge across the creek.
