Aspinall Operations Update

See below for the CBRFC forecast slides for the Aspinall unit and USBR slides on Aspinall operations.

The highlights are:

  • CBRFC did adjust the Gunnison snow model based on ASO data.
    • They are only considering incorporating ASO data for areas that have had ASO flights for 5ish years and they are confident about it making their model more accurate
  • The runoff forecast dropped and is now putting the Aspinall unit in the moderately dry hydrologic category instead of the average dry category. This category has no half-bank duration targets.
  • The North Fork is pretty dry this year. Inflow to Paonia is forecasted at a little over 50%.
