U.S. Fish & Wildlife ServiceMeasure CR 3: McKay Creek Flow Responsible Permittee: OID Species Affected: bull trout, steelhead, sockeye salmon Minimum Flow in McKay Creek: Water will be bypassed and/or released into McKay Creek, as needed, to provide the minimum instream flows specified in Table CR 3 during the active irrigation season 1 . Outside the active irrigation season, McKay Creek will be allowed to flow without diversion by OID or its patrons. Table CR 3. Minimum instream flows for McKay Creek during the active irrigation season. Minimum Daily Average Instream Flow During the Active Irrigation Season 1,2 Stream Reach Prior to McKay Creek Water Switch After Full Implementation of McKay Creek Water Switch 3 Measurement Location Jones Dam (RM 5.8) to Dry Creek (RM 3.9) Equal to flow immediately upstream of Jones Dam, to a maximum of 2.0 cfs Equal to flow immediately upstream of Jones Dam, to a maximum of 11.2 cfs At Jones Dam Dry Creek (RM 3.9) to Reynolds Siphon (RM 3.2) 3.0 cfs Equal to flow immediately upstream of Jones Dam, to a maximum of 12.2 cfs At Reynolds Siphon Reynolds Siphon (RM 3.2) to mouth 5.0 cfs Equal to flow immediately upstream of Jones Dam, to a maximum of 14.2 cfs At Cook Inverted Weir (RM 1.3) 1 For purposes of this conservation measure, the active irrigation season on McKay Creek is the period of time during which water is being diverted from the Crooked River into the Crooked River Diversion Canal and/or released from Ochoco Reservoir into the Ochoco Main Canal for irrigation. This period typically occurs from mid April to mid October, with actual dates varying slightly from year to year. 2 Actual flows in McKay Creek may be ±10% of flows specified in Table CR 3 due to inherent inaccuracies in flow measuring devices. Additional flow variation may result from circumstances beyond the control of OID, such as irrigation diversions by parties other than OID and its patrons. 3 Flows in this column are based on full implementation of the McKay Creek water switch, which is expected to replace 11.2 cfs of live flow diversion upstream of Jones Dam with water from the Crooked River. In the event of a partial or phased switch, the instream flow below Jones Dam will reflect the actual McKay Creek switch instream right above Jones Dam. McKay Creek Water Switch: OID will fulfill its obligations under the Memorandum of Understanding (MOU) between OID and the Deschutes River Conservancy (DRC) effective as of May 30, 2017, subject to the terms and conditions of the MOU. OID will not exercise its termination rights under the MOU, provided that the DRC fulfills its obligations under the MOU and OID determines, in its discretion, that the contingencies described in Paragraph F of the MOU are satisfied. McKay Creek is also affected by CR-4 and CR-5, conservation measures that are not dependent on stream gauging.
