<br />when water depths approached levels normally observed entering winter months. On <br />~ 15 August, numerous dead carp were observed at The Stirrup site. However, <br /> <br />razorback sucker carcasses were not observed. Razorback sucker were not captured <br />during sampling immediately following observation of the fish kill. Weekly visits to the <br />site were made beginning in mid July of 2000 and dead razorback sucker were never <br />observed. Mortality of razorback sucker in The Stirrup site probably occurred between <br />4 June (date of disconnection) and the July visits. This was likely a result of an oxygen <br />deficit from high biochemical oxygen demand of decomposing organic matter. <br />At Baeser Bend a fish kill occurred over the weekend of 12 - 13 August 2000. <br />~ Dead razorback sucker were not observed at the site on 11 August. On Monday <br /> <br />August 14, several hundred dead razorback sucker were observed along the shoreline <br />at the site. Trammel net sampling resulted in the capture of several razorback sucker, <br />indicating some survival. <br />Just prior to both observed fish kills water quality concerns resulted in the <br />~ decision to pump water into the sites. Pumping was scheduled to begin during the <br />week of 14 August 2000. Pumping was initiated at Baeser Bend on 15 August. <br />Although water conditions in Above Brennan never resulted in a fish kill, water was <br />~ pumped into the site as a precautionary measure beginning on 18 August 2000. <br />Pumps at both sites were run periodically until 22 September 2000. During this period <br />about 25 cm (10 inches) of water depth was added to each site. This added water <br />depth only lasted for about one week. <br />Water quality conditions in Baeser Bend remained poor and the decision was <br />~ made to mechanically remove most surviving razorback sucker and transport them to <br />12 <br /> <br />
