The City government
continued to evaluate additional sources of supply to meet the needs
of the growing municipality. After much study and debate, improvements
were made to the Jones Falls supply in 1862 including the construction
of Lake Roland Dam and Reservoir, the Jones Falls conduit, Lake Hampden,
and Mount Royal Reservoir at a cost of $2,400,000. Lake Chapman (site
of Druid Lake) was complete in 1865 to provide additional supplies.
Druid Hill Reservoir was constructed in 1873 to provide high service water
supplies. As demand increased coupled with recurring droughts, the City
sought additional water supplies. Construction of a permanent supply from
the Gunpowder Falls was completed in 1881 at a cost of $4,500,000.
works consisted of construction of a dam across Gunpowder Falls
at Ravens Rock, formation of Loch Raven Reservoir, construction
of a tunnel connecting the reservoir with Lake Montebello, and construction
of a conduit connecting Lake Montebello to Lake Clifton.
public health concerns, chlorination of the water supply was instituted
in 1910 followed by construction of a water filtration plant at
the Montebello site. Montebello Filtration Plant 1, situated on
the east side of Hillen Road, was placed into operation in 1915
after a two-year construction period.
Construction of Loch Raven Dam was also completed in 1915 with the
spillway crest extended to its present elevation in 1923. Annexation
of additional land by the City in 1918 spurred the construction of
Montebello Plant 2, which was placed into operation in 1928. Other
major construction projects occurring the first half of this century
included construction of the Montebello-Druid Lake conduit and Prettyboy
Dam in 1932, construction of the Gunpowder-Montebello Tunnel in 1941,
and construction of the Patapsco - Montebello Tunnel in 1950.
to continue to meet the growing water demands, the Ashburton Filtration
Plant, located on Druid Park Drive near Druid Hill Park in Baltimore
City and Liberty Dam and Reservoir were completed in June of 1956.
Additional major projects completed in the last half of this century
include several upgrades to the Montebello plants and construction
of the Deer Creek Pumping Station in 1966. Construction of this
pumping station allowed the City to withdrawal water from the Susquehanna
