Lago de
Cidra is located in the municipio of Cidra, and was constructed
in 1946 by the Puerto Rico Aqueduct and Sewer Authority (PRASA). This
reservoir was constructed as a public water-supply source to
serve the municipios of Guaynabo, Aguas Buenas, Cidra, and Comerío, among others.

This reservoir has a drainage area
equal to 8.6 square miles (13.8 square kilometers).
Originally, the reservoir had a water-storage capacity of 5,302
acre-feet (6.54 million cubic feet), but by 1997 the capacity
had been reduced by sediment infilling to 4,670 acre-feet (5.76
million cubic meters). The Guaynabo Filtration Plant
produced 20 million gallons per day ( 75.7 million liters per
day ) to serve about 160,000 persons.

The U.S. Geological
Survey, in cooperation with PRASA, has produced a number of reports
regarding effects of sediment infilling on storage capacity of Lago
de Cidra, including:
Soler-López, L.R.,
1999, Sedimentation Survey of Lago de Cidra, Puerto Rico,
November 1997: U.S. Geological Survey Water-Resources
Investigations Report 99-4144, 19 p., 1 pl.
In addition, the
U.S. Geological Survey, in cooperation with local government
agencies, has produced a number of reports regarding the effects
of sediment infilling on the storage capacity of principle
water-supply reservoirs of Puerto Rico. The results of
these surveys are summarized in "Sedimentation
survey results of the principal water supply reservoirs of
Puerto Rico,"
These
reports can be purchased at a nominal cost by contacting Information
Desk at the U.S. Geological Survey,
GSA Center, 651 Federal Drive, Suite 400-15, Guaynabo, PR 00965, 787-749-4346
ext. 296. Please contact Water-Use
Information, 787-749-4346 ext. 259, if you have other questions
regarding water supply in Puerto Rico.
The
table below shows the relationship between reservoir level and
available water. This information is presented in graphical format
in the figure above. Note that an acre-foot is a volume of water
that would cover an acre (43,560 square feet) to a depth of 1
foot.
