Gents:
FYI. We’ll see the river drop about 400 cfs for a month. The water supply looks bleak above Canyon Ferry at this point and BOR doesn’t want to spill water. Grant and Brad (his new fish tech) will try to get an idea of any dewatered brown trout redds to see if we will see any impacts from this operation change/maintenance.
