  2. Partners 1. Hood River Water Planning Group Formed in 2008: includes HRC, CTWS, HRWG, EFID, FID, MFID, ODFW, DEQ, NMFS, other. • 2. United States Bureau of Reclamation • $250,000 in-kind. 3. Oregon Water Resources Department $250,000 cash.

  3. Goals Evaluate: 1. Current and future water demands. 2. Water conservation opportunities. 3. Groundwater availability. • 4. Impacts to streamflow from climate change. • 5. Impacts to fish habitat from climate and water conservation alternatives. • 6. Alternatives to maintain viable future water supply.

  48. AWS changes (lowest 20% of streamflow, median climate)

  49. Potential Actions

  50. Recommendations • Implement irrigation efficiency upgrades • Reduce or eliminate overflows and canal seepage in EFID • Further evaluate expanding storage at Green Point and Laurance Lake • Collect data for use in future analysis of reservoir storage in EFID • Collect/use additional data for optimal streamflows for aquatic habitat • Expand groundwater data collection • Implement projects for increased summer streamflow and flexibility • Refine modeling that was done as part of this Basin Study -particularly glacier, groundwater, stream temperature • Other?
