Corps finds crack in holding tank for adult fish at Lower Granite Dam

A crack recently developed in a concrete holding tank that is part of an adult fish-trapping facility at Lower Granite Dam.

Officials with the U.S. Army Corps of Engineers are considering their options to deal with a crack in a concrete tank at an adult fish-trapping facility at Lower Granite Dam west of Lewiston.

Corps spokesman Bruce Henrickson said the crack was discovered last month and appeared while a nearby well that is part of a wastewater treatment facility was being demolished.
