  1. Hood River Basin Study Agenda 1). Goals 2). Partners 3). Study Overview 4). Recommendations

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

  3. Partners 1. Hood River Water Planning Group Formed in 2008, stakeholders throughout Hood River Basin 2.

  44. 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?
