About Loch Raven

Loch Raven Reservoir DamThe Loch Raven dam was originally built in 1881 in order to feed water to Baltimore City lakes and increase the city’s water supply, but the large reservoir we’re now familiar with wasn’t started until after 1914, when a 51-foot dam was built and water from the Gunpowder River began filling up behind it, eventually containing 1.5 billion gallons of water.  In 1923, the dam was increased to 240 ft, it’s current height, and the true reservoir was created, now holding 23 billion gallons of water, enough to sustain the State of Maryland for approximately 50 days, a fact that is startling when one sees the size of the reservoir.

According to voiceshakes.wordpress.com, a hidden city can be found beneath the waters of Loch Raven Reservoir.  This city was named Warren and was located near the Warren Rd. Bridge.  Old building foundations can be found throughout the reservoir, especially in the woods near Merryman’s Point, where members of the Merryman family most likely lived prior to the dam being built.
