can continue without change. Two possible adjustments do present themselves,
first would be to include a measure of turbidity. However, this would have to
a three-class visual assessment. Direct measurements are probably not possibl
disturbing the fish community, though, and biasing the sample. Secondly, it m
to drop the minimum depth requirement to 0.2 - 0.25 m. When graphed, depth of
squawfish backwaters presents a bell shaped curve peaking in this range with a
extending to 2.0 m. Also, there are numerous records of high catches of Color
shallow backwaters. During ISMP xOY sampling in the middle Green River in 199
highest catch of Colorado squawfish (n=169) was in a backwater 0.25 m deep.
