A high-quality fishery water is defined as a stream classified for the beneficial use of coldwater permanent fish life propagation, coldwater marginal fish life propagation, or warmwater permanent fish life propagation. The design low flow for a high-quality fishery is the minimum 7-day average low flow that can be expected to occur once in every 25 years (7Q25). During these low flow periods, the water quality criteria set forth in §§ 74:51:01:45 to 74:51:01:47, inclusive, and in § 74:51:01:56 do not apply to the water but all surface water discharge permit limits remain in force.
