Instream Flow Incremental Methodology

Much of the analysis is completed using the Instream Flow Incremental Methodology (IFIM), a procedure used to view instream flow and habitat at selected points within a river, over some period of time. 

IFIM was developed over a 15 year period and has evolved into a river network analysis incorporating fish habitat, recreational opportunity, and woody vegetation responses to alternative water management schemes.
