Passage Barrier Removal - Dutch Flat Dam

Location: West Fork Little Bear Creek, Troy, Idaho
Description: Fish passage is greatly impaired by the old Dutch Flat Dam (sometimes referred to as the Troy Dam), which no longer serves a community purpose. The Dam was originally constructed to create a municipal water reservoir in 1919. By 1925, the reservoir had filled with sediment deposition from farming and logging activities upstream and was abandoned. The Idaho Department of Fish and Game (IDFG) has confirmed steelhead population presence at the bottom of the dam via fish survey work. Removing the dam is the best way to restore fish passage, spawning habitat, and natural stream function. Latah SWCD received permission from the City of Troy, in early 2010, to begin investigating the removal of the dam. Latah SWCD has contracted with K35 to develop engineering designs for removal of this fish passage barrier.
Status: Engineering designs completed, implementation proposals funded, work to commence in 2013.
