National Dam Inspection Program. Druid Hill Lake (NDI-ID Number MD-109) Patapsco River Basin, Jones Falls, Baltimore City, Maryland. Phase I Inspection Report

摘要

Druid Hill Lake is impounded by an earthfill dam consisting of a northern, eastern, and southern embankment. The lake is a reservoir for filtered water which is pumped from the Montebello Water Purification Plant. The dam, completed in 1871, was recognized by the American Society of Civil Engineers in 1971 as a National Historical Civil Engineering Landmark. The water level of the reservoir is maintained at approximately elevation 212. The maximum pool level of elevation 216 represents the top elevation of the overflow pipe located at the eastern end of the reservoir. Water normally leaves the reservoir by gravity flow through an outlet header at the eastern end of the lake. Because all inflow into the reservoir is controlled, with the exception of rainfall directly on the lake and a small amount of surface runoff, flood routing and detailed hydraulic and hydrologic analyses are not required.
