' A 24 hour observation on CS714 was conducted on 24 September 1996. CS714 was
initially located along the bedrock shelf at the lower end of the pool at RM 95.4 The fish
' remained in this position and inactive until dark. By 8:45 p.m., the fish had repositioned
near the upper end of the pool below a submerged sand bar and had become very active.
' CS714 remained active until nearly midnight at which time it moved back along the
bedrock shelf and remained mostly inactive throughout the rest of the observation period
t (Figure 14). CS714 moved upstream approximately 700 feet and then back downstream
the same distance during the 24 hour observation.
