Tongue River Reservoir Professional Review and Guide

"In the heart of the northern plains coal country is one of southeast Montana’s finest recreational jewels, the Tongue River Reservoir, a state record-winning fishery. Because this reservoir is located a few miles north of the town of Decker in Big Horn County and 5 miles north of the Wyoming state line, it is heavily used by citizens of both states.

Tongue River Reservoir, a prairie fishery widely used by boaters, swimmers, picnickers, and anglers, is a long narrow channel, approximately 5 miles by 0.8 mile. Although this is a prairie reservoir, there are a few trees around the shoreline. The reservoir was created on the Tongue River when the State of Montana built an irrigation storage dam. In past years, high water has done serious damage to the dam. Repairs may result in much better water levels after 1999, but the reservoir will remain low during repairs."
