Establishment of minimum perennial streamflows is a high priority of the Water Resources Commission and Water Resources Department. Minimum perennial streamflows are established as administrative rules to support fish and aquatic life or minimize pollution. Minimum streamflows are included in applicable basin program statements. These rules include the definitions, standards, process and criteria for the evaluation of minimum perennial streamflow applications submitted by the Department of Fish and Wildlife or the Department of Environmental Quality to the Water Resources Commission under the provisions of ORS 536.325.
