Figure 13. Frequency of use of habitat types by adult Colorado squawfish in the 15-mile reach
study sites during summer periods of moderate flow and low flow levels. Top two graphs
represent the mean frequency of use averaged across fish. Bottom graph represents the percent
locations in each habitat type of the total locations made in each period, irrespective of the number
of locations per fish.
