NOTES

This forecast represents our "best guess" of reservoir project pool elevations and releases for the next three days.  In general, it assumes no significant rainfall during the forecast period.  Final decisions on all operations (changes in project release) are made on the day of the operation.  Future operations shown on this forecast are as expected, but not promised.

On the top panel, under "Pool Elevations" the following definitions apply:

  • Minumum Pool - the minimum pool elevation for the project.
  • Winter Max Pool - the maximum Winter Pool elevation for the project.
  • Summer Max Pool - the maximum Summer Pool elevation for the project.
  • Full Pool - the elevation of the pool at maximum flood control storage.

"Flood Storage Capacity Used" is the amount of the lake's floodwater storage which is already filled.  The lake volume between Summer/Winter Pool and Full Pool is the amount of "empty space" that the lake is supposed to keep available for storing floodwater.
