Reservoir Pool Elevation: Considerations for Long-term Asset Management and Planning

Reservoir Pool Elevation: Considerations for Long-term Asset Management and Planning

After completing this lesson you will be able to:

  • Describe the projected changes in climate that are likely to affect reservoir elevation
    • Describe key features of projected temperature changes in for the Western United States (mean annual temperature, seasonality).
    • Describe the key features of projected changes to precipitation for the Western United States (amount, phase, timing, intra-year and inter-annual variability).
  • Describe the impacts on reservoir elevation from changes to temperature, precipitation and streamflow due to climate change
    • Describe climate impacts that change inflows, including the following:
      • Streamflow changes due to changes in the timing, amount, and phase of precipitation
      • Streamflow changes due to changes in temperature including seasonality and efficiency of snowmelt runoff
    • Describe climate impacts that change direct losses from reservoirs, including the following:
      • Evaporation changes due to changes in temperature
    • Describe climate impacts that change outflows, including the following:
      • Changes in irrigation demand due to changes in temperature and seasonality
      • Evapotranspiration changes due to changes in temperature
  • Describe the typical challenges that changes in reservoir elevation may pose to asset management and planning
    • List and describe several examples of impacts to asset management (e.g. infrastructure investment) due to climate change
