In today’s regulatory climate, enlarging existing reservoirs is one of the few potentially environmentally feasible options for increasing the capacity and reliability of existing surface water reservoirs to meet growing human needs for water, renewable energy, recreation and environmental benefits.

As dams age and near the end of their functional service life, consideration of reservoir enlargement is often beneficial as part of dam rehabilitation to extend the service life of the facility.

Feasibility of reservoir enlargement depends on many site specific factors including reservoir topography, geology and seismicity, dam design and safety, impacts on ongoing project operations and environmental issues.
