| Description | The Oregon Department of Environmental Quality (ODEQ) and the Washington Department of Ecology (Ecology) are making a decision on the need for the 115% forebay total dissolved gas (TDG) requirement to regulate spill during fish passage spill on the Columbia River and Lower Snake River dams. Oregon and Washington both have 110% TDG criteria that are modified for fish passage in the Columbia and Snake Rivers. The requirements for the Columbia and Snake Rivers include a 115% TDG requirement in the forebays and 120% in the tailraces. This document provides technical decision-making information on forebay total dissolved gas issues, an overview of the regulatory history and requirements as described in the Columbia River and Lower Snake River Total Dissolved Gas Total Maximum Daily Loads, and summarizes and evaluates the technical information presented at the total dissolved gas Adaptive Management Team (AMT) meetings. |
