Knife River provided to ESC a revised dewater plan. Inspectors 420 and 460 walked site. Water is being transferred under Warm Springs Road to the south side, (same owner). Area is highly vegetated. Wallings Ditch flow is un-noticeable & clarity appears to be unclear. Dewatering has not reached Walling at the time of our inspection. Recommended to Knife River to collect turbidity samples from Wallings to determine NTU numbers. Ok to have discharge into Wallings if turbidy is in compliance with State Of Idaho Water Quality Standards. Also informed Knife R. to continue to monitor dewatering over the weekend and if discharge into Wallings occur and exceeds standards to discontinue discharging. Boise City will follow up next week.
