Proportion of Flow Diverted

A named list where each component contains a dataset with the proportion of flow diverted within watersheds for use with the CVPIA SIT Salmon Population Model. The components of the list contain output from two different Calsim II BiOp runs:

  • biop_2008_2009: output from the 2008-2009 Calsim II BiOp run.

  • biop_itp_2018_2019: output from the 2018-2019 Calsim II BiOp run.

Details

The proportion diverted was calculated using 'FLOW-CHANNEL' and 'FLOW-DELIVERY' nodes from CALSIM II. The nodes and calculation for each watershed are outlined below

The diversions of Antelope Creek, Deer Creek and Mill Creek are represented by one diversion node. Diversions for these creeks were estimated in proportion to their flow. Elder Creek and Thomes Creek are also represented with a single node and their diversions were estimated using the same method.
