Logan River

The Logan River watershed is located in the heart of the Bear River range with headwaters near the Utah-Idaho border. The river flows southwest through Logan Canyon - a landscape dominated by formerly glaciated peaks, limestone cliffs, and the occasional sinkhole. The underlying bedrock has numerous caves that create natural springs that contribute to the river’s year-round discharge. Near the canyon’s mouth, the river is dammed in three locations (First, Second, and Third dams) for hydroelectric generation. After exiting the mountains, the river flows west through Cache Valley and is impacted by a mixture of agricultural and urban environments. The Logan River converges with the Little Bear River in central Cache Valley before flowing north to the main stem of the Bear River and Cutler Reservoir.
