The quarry was active since before the Civil War. It was a deep hole in the ground, operating as a mine until 1999 when plan- ning began for the current development that includes housing, retail stores, and a large lake and park. The ensuing 40 acre lake is one of the deepest bodies of water in Maryland at 365 feet deep, with the Are you a member of the bottom of the lake at its deepest point 29 feet below sea level!

Before starting, the plan had to meet environmental standards on three levels—county, state and federal. A Baltimore County approved land reclamation plan, a state Department of Environment approved mining recla- mation plan, and permits by the state Department of the Environment and the U.S. Army Corps of Engineers had to be submitted and approved. Phew! Not quite like plugging a hole in the dam with one’s finger… Eric spread out his maps on the gazebo floor for us to see. The brown one (pictured) shows the 900 acre watershed outlined in yellow, the current development in red, and the location of the original streams (Moore’s Branch and Wellwood Branch) prior to diversion in blue. The lake fills by direct precipitation, natural ground water and the flow of a diverted stream. It took 10 years to fill up, and continues to be fed by the stream. Water-level control consists of a complicated discharge structure consisting of a weir wall located in an underground vault where water from 60-feet be- neath the surface of the lake flows through a chamber that was designed to keep the lake surface at an elevation of 336’. Water overflow takes place at the east end of the lake from inside that structure, and is piped to the stream bank near Greenspring Avenue.
