Comparison between total catch per unit effort (Fish/h) for <br />sub-adult and adult Colorado squawfish collected by <br />electrofishing in the plunge pool immediately downstream of <br />the Redlands Diversion Dam and in the 2.2-mile reach of the <br />Lower Gunnison River, Colorado, March 1994 to November 1995. <br />Hydrology <br />River Discharge <br />The maximum daily flow was about three times higher and the total annual <br />discharge was about two times higher in the Gunnison River in 1995 than 1994. <br />The total annual discharge for the Gunnison River at the USGS streamflow gage at <br />Whitewater was 1,484,000 AF (784,395 cfs) in 1994 compared to 3,222,000 AF <br />(1,624,310 cfs) in 1995. The maximum daily discharge was 6,040 cfs in 1994 <br />compared to 17,300 cfs in 1995. The mean daily May and June flow in 1994 was <br />3,640 cfs compared to 11,196 cfs in 1995. The mean daily flow for July, August, <br />and September in 1994 was 1,140 cfs versus 5,875 cfs for the same three months <br />in 1995. In 1994 in the 2.3-mile reach, there were 86 days when the flow was <br />less than 1,000 cfs and 14 days when the flow was less than 300 cfs during these <br />19
