squawfish ecology and behavior as it related to attempts to artificially
establish the squawfish in the reservoir. A secondary objective was to
determine if squawfish could become a viable sportfish in the reservoir.
Methods
Study area
The study area (Figure 1) encompassed the White River from 16 km
above Kenney Reservoir (RK 192.7) to the Colorado - Utah border (RK
115.5). In 1988 and June, 1989, the river was only sampled from 16 km
above the reservoir to 16 km below. As it became apparent the squawfish
were moving downstream, the study area below the dam was extended to the
CO/UT border. The river was subdivided into five sections as indicated in
Figure 1.
Kenney Reservoir's upper limit was designated as RK 175.9 and the
lower limit as RK 167.8 at the dam axis. The reservoir is 8 km long and
1.2 km across at it's widest point, with a maximum depth of 15.2 m near
the dam. When filled it covered 680 surface acres and held 13,800 acre
feet of water. The high silt load of the White River decreased the
reservoir's capacity an undetermined amount by filling the upper end of
the reservoir with silt deposits for approximately 1.5 km (Figure 2).
Flow from the White River is retained in the reservoir for an average of
two days (Behnke 1981). There is an outlet gate at the base of the dam
but most of the flow was released over the spillway during the study due
to damage incurred by the outlet gate.
