2. Use the Little Snake River to study and understand which physical factors
restrict nonnative species numbers and their distribution in the Little Snake
River. Physical factors that warrant additional study include:
the unique geomorphology of the watershed,
discharge events including runoff, baseflow, and flash floods,
water quality especially turbidity and temperature, and
extreme variability and amplitude of seasonal discharge,
seasonal sediment load, and diel water temperatures during
baseflow.

3. Study the Little Snake River to understand the influence of extremely low
baseflow events on the native and nonnative fish community.

4. Consider the use of population estimates as a tool for monitoring fish
communities in Upper Basin studies and modify the technique for use on
larger rivers.

Key words: Colorado squawfish, humpback chub, Little Snake River, native fishes,
nonnative fishes, removal population estimate, reproduction,
spawning, tributary.
