    The applicant is proposing a maintenance dredging plan designed to open up a braided side channel of the Bitterroot River that is prone to sediment buildup. Sediment annually blocks the channel, resulting in diminished and inadequate flows to the Supply Ditch Headgate. The applicant is proposing to perform maintenance dredging up to two times per year to ensure the delivery of 8,000 miner’s inches (200 cubic feet per second) of water through the diversion structure during the irrigation season.
