dam building
Blocking river flow
Dam building is the construction of barriers across waterways to control water flow, create reservoirs, or generate hydroelectric power.
The term applies both to human engineering projects and to the instinctive behavior of beavers, who build dams from branches, mud, and stones to create ponds for their lodges.
