Swanson Lake and Trenton Dam

Trenton Dam, on the Republican River near Trenton, Nebraska, is an earthfill structure with a structural height of 144 feet. The spillway is at the left abutment. Two gated sluiceways permit river releases. A concrete conduit through the base of the dam near the right abutment provides for releases through a stilling basin to the Upper Meeker Canal to serve lands of the Meeker-Driftwood Unit. These lands are located along the south side of the Republican River from the dam to a point about 8 miles east of McCook. Regulation of releases through the conduit is by a 4-foot-square high-pressure gate at the control house adjacent to the stilling basin. The reservoir behind the dam is called Swanson Lake.
