<br />Uil157g <br /> <br />Purpose <br /> <br />The Hydrology Committee shall review and evaluate all hydrology related information pertinent <br />to this Implementation Program. The Committee shall provide advice to the Biology Committee <br />and Coordination Committee regarding hydrologic aspects of this Implementation Program for <br />endangered fish and evaluate proposed changes to the San Juan Basin model and the flow <br />recommendations. Examples of Hydrology Committee work include, but are not necessarily <br />limited to, the following areas: <br /> <br />. Review and comment on the San Juan Basin Hydrology Model, including providing <br />recommendations for model improvements and input data updates. Review and suggest changes <br />or revisions to the model documentation maintained by Reclamation to ensure that all <br />assumptions and model operating procedures are fully documented and up to date. <br /> <br />. Evaluate proposed changes to the operating rules for San Juan Basin Reservoirs and the impact <br />ofthose changes on the ability to continue to provide flows for recovery of endangered fish and <br />meet the authorized purposes of the project. <br /> <br />. In coordination with the Coordination Committee and the Biology Committee, evaluate, <br />recommend and propose changes in environmental baseline depletions to the Service, with the <br />understanding that the Service has the authority and responsibility for making the final decision <br />on any changes to the environmental baseline. <br /> <br />. In coordination with the Coordination Committee, evaluate water right and compact issues <br />pertinent to providing flows for endangered fish, including whether or not diversion <br />requirements of water right holders can be met before storage releases to benefit endangered fish <br />species are made, with the understanding that any final decisions on these issues rest with <br />appropriate state or federal agencies. <br /> <br />. In coordination with the Biology Committee, review and comment on issues related to channel <br />morphology, and the relationship among flows and geomorphology. <br /> <br />. Iftime permits, the Hydrology Committee, in coordination with the Biology and Coordination <br />Committees, will provide input to Reclamation on Navajo Dam operations during unforeseen <br />conditions that may not be covered by the flow recommendations and Navajo Dam operating <br />criteria, <br /> <br />. During the Adaptive Management process evaluate and make recommendations on the known <br />and potential hydrologic issues related to the flow recommendations, <br /> <br />. Provide coordination between Reclamation and this Implementation Program during <br />Reclamation's public Navajo Reservoir operational meetings. <br />
