Hydrolog)' Committee

Chanae Number 16:

The Sub-committee recommends that the responsibilities of the Hydrology Committee be refined
to read as follows:

1. Review and comment on the San Juan River Basin Hydrology Model maintained by the
Bureau of Reclamation for use in evaluating the flow recommendations and the
hydrologic impacts of proposed water development and management activities on the
ability to maintain flows in accordance with the flow recommendations. including
providing recommendations for model improvements and input data updates and
reviewing model applications as appropriate;

2. review and suggest changes or revisions to the model documentation maintained by
Reclamation to ensure that all assumptions and model operating procedures are fully
documented and up to date;

3. evaluate the physical availability of water and operating rules for San Juan River Basin
reservoirs for the ability to meet the diversion requirements of water right holders and the
authorized purposes of the reservoirs and to provide flows, including releases from
reservoir storage, to benefit endangered fish species in the San Juan River, with the
understanding that decisions on water project operations rest with appropriate federal and
state agencies;

4. review and comment, in coordination with the Biology Committee, on issues related to
channel morphology and the relationship among flows and geomorphology;

5. provide coordination between Reclamation and the Program in the development of
annual operating plans for Navajo Reservoir, including providing, in consultation with
the Biology Committee and the Coordination Committee. input to Reclamation on
Navajo Dam operations during extreme hydrologic conditions that may not be covered by
the flow recommendations and Navajo Dam operating criteria; and

the implementation of the flow recommendations.
