Instream Flow Conservation Plan Sample Clauses

Instream Flow Conservation Plan. The Instream Flow Conservation Plan is a plan developed by the Agencies and the Participating Landowner to maintain instream flows consistent with a natural hydrograph (i.e., spring spawning flows, bankfull discharge events, and sustained baseflows) to support all Arctic grayling life histories in the Centennial Valley. Under this Plan, Participating Landowners would agree to reduce irrigation or stockwater diversions at certain times of the year to maintain flow targets. For flow target development and methodologies, see Appendix A. Application of the Instream Flow Conservation Plan Following is the description of how the streamflow targets are applied in the Centennial Valley CCAA. • Total available streamflow in each stream is determined. This may include direct wading measurement using area-velocity, staff gage and rating table, ditch measuring flumes or a combination of these methods. • Normal or dry year targets for each stream are determined for spawning/rearing or base flow conditions (Table 1, Appendix A) • Once a dry or normal year target determination is made, it will remain in effect through the remainder of the period (i.e., spawning/rearing or early spring or summer base flow period). Within the next period, the target condition will be reassessed. • The diversion of water will be curtailed so that the flow targets are met. FWP or agent(s) will contact Participating Landowner to adjust the amount of diverted flow needed to meet the stream flow targets in Table 2. Priority water calls can still be placed from senior users to junior users regardless of agreements or arrangements formed under the Agreement. • The natural flow of the stream without any diversion will be the default flow target if it is less than the target listed. Expected benefit: The combination of improved irrigation management, management and compliance of water rights, providing alternative stock water sources, potential changes to water rights and implementing Instream Flow Conservation Plans will lead to improvements in streamflows within the Project Area. The cumulative effect of the individual actions described above will improve available habitat and maintain migratory corridors for all life history stages of Arctic grayling.
