Sediment is being removed from the channel between Upper and Lower Twin Lakes to improve water quality for wildlife, boaters and the overall community.

A Rich History
Twin Lakes, previously named Fish Lake, became a popular vacation spot in the early 1900’s. People arrived at the lake by horse-drawn wagon or train. Several steam-powered boats served the lake by picking people up and ferrying them to their destinations and by delivering groceries to vacationers’ cabins. Twin Lakes had a sociable atmosphere created by various hotels, resorts, dance halls and boat parades. Bing Crosby, prior to his notoriety, and his cohorts performed locally and were known to canoe to Rathdrum via the creek on Saturday evening.
