Table K.3. Radiotelemetry data for six adult Colorado pikeminnow (CS) in the Upper Colorado (CO) and Gunnison <br />(GU) rivers, 1998. Note: the number of days fish were contacted included both those recorded by <br />automated data logging stations and by boat; RM=river miles; 15- and 18- refers to the 15-Mile and <br />18-Mile Reaches of the Upper Colorado River near Grand Junction, CO; Ruby/Horsethief canyons: river <br />mile 130.5-152.7. Fish were equipped with LOTEK@ model MCFT-7A radiotags. <br />w <br />Number of Contacts (Da) <br />CS Colorado ysunm son F.

This is <br />different from fish implanted in 1996 and 1997 because four CS were translocated upstream in 1998. <br />e translocated from the initial capture site following radiotag implantation upstream of the Redlands Diversion <br />Dam in 1998. <br />f CS implanted with LOTEK° radiotags as part of the Grand Valley Irrigation Diversion Dam fish passage <br />evaluation (see Burdick 1999; Recovery Program Project Number CAP-17).
