3. If Colorado squawfish spawning is documented in the reach, flows
necessary for this aspect of their life history should also be
identified.
4. The BR streamflow gage should be used in the future to monitor flows
in the reach because a) it is a direct reading, b) it does not require
subtracting withdrawal flows for irrigation from gages further
upstream, and c) instantaneous data can-be retrieved electronically
via satellite downlink. The USGS gage at Whitewater that measures
streamflow for the mainstem Gunnison River and CDWR gage that measures
water withdrawn by the Redlands Canal should only be used to cross-
check flows or used as a backup in the event that the BR gage is not
operational.
