Reservoir Development Areas

A Reservoir Development Area (RDA) is a zone established by the Water Security Agency (WSA) around seven WSA-owned reservoirs (listed below). These areas were created to mitigate risks to public safety and private property while ensuring safe and efficient reservoir operations. The Water Security Agency Act and Regulations authorize the WSA to regulate developments within an RDA, such as houses, boat launches, marinas, and cottage developments.

WSA-owned reservoirs often have multiple functions and must be operated as needed to manage competing interests such as:

• flood control;
• water supply;
• hydro-electric power generation;
• recreational;
• source water protection; and,
• to meet the needs of the ecosystem.

The RDA allows WSA to regulate development to ensure the efficient operation of these structures and to help mitigate risk to public safety, private property, and developments of these reservoirs.
