Trego Hydro, located on the Namekagon River about eight miles north of Spooner Wisconsin, is a run-of-the-river operation. The Trego dam was built in 1927 and was refurbished in 1980 with repairs to the power plant, spillway and piers. The dam creates Trego Lake, a six mile long, 470 acre impoundment only a half mile across at its widest point. Fishing is popular with residents and vacationers; however, recreational use of Trego Lake is light since many people are drawn to the larger lakes nearby. The plant is remotely operated from the Wissota hydro plant.
The dam creates Trego Lake, a six-mile-long, 470-acre impoundment only half-mile across at its widest point. The steep banks of the lake are rimmed by stands of jack pine and aspen, with many private cabins among trees.
Fishing is popular with the residents and vacationers who visit the resorts along the lake. However, recreational use of Trego Lake is light since many people are drawn to the larger lakes nearby. As a result, Trego Lake tends to be a peaceful, secluded near-wilderness area.
