Maryland's Dam Safety Program

MDE’s Dam Safety Program ensures all dams in Maryland are designed,
constructed, operated and maintained safely to prevent dam failures and
the consequences of failure. MDE’s responsibilities
include conducting inspections of dams based on their "hazard class,"
issuing permits for construction, repairs or for modifying dam
structures; conducting construction inspections and working with dam
owners and emergency management professionals to develop and exercise
'Emergency Action Plan' to be used in the event of dam failure. Download here the MDE Dam Safety Program Fact Sheet.

Maryland Dams




A dam is defined as any obstruction, wall, or embankment, together
with its abutments and appurtenant works, constructed for the purpose
of storing water. Dams may be constructed of earth, concrete, wood or
rock. Most dams in Maryland consist of an earthen embankment to store
water and a combination of spillways designed to pass water safely
around or through the facility.

Dams can provide many benefits for Maryland's citizens including
water supply, flood control, hydroelectric power, fishing and
recreation. However, dams can also be a great threat to the safety and
well being of downstream property and people if they are not properly
constructed or maintained. The State of Maryland has been assuring the
safety of dams since 1934 through a permit and inspection program. The
laws governing dam safety are xxxx by MDE’s Dam Safety Division.

Examples of Maryland Dams

There are over 400 dams in Maryland, ranging in height from six to
296 feet. The majority of Maryland's dams are earth fill or earth and
rock fill embankment dams such as Savage River Dam. There are also several large concrete and "slab and buttress" dams that provide storage for drinking water such as Liberty Dam, Prettyboy Dam and Brighton Dam.

Little Seneca Dam, pictured above, is an earth fill embankment dam
that provides recreation and supplemental releases to the Potomac River
during low flow conditions on the Potomac River.
