Table 3. Population Estimates of Darter Species in the Blue River at
Selected Locations during a Severe Drought Year in 1999, 2000 and 2001. PE =
Population Estimate, CI = 95% Confidence Interval. All Numbers Reflect Numbers
per 100 ft2. The first number for Milltown Dam is the permanent monitoring site
just below the dam. The second number is the first downstream riffle where
spotted and bluebreast darters have been located.
