The river above Hartland Diversion was not <br />sampled. Although relatively few northern pike were captured there by Burdick (1995j, that <br />reach was not sampled in this study to provide a source of undisturbed fish to determine how <br />quickly northern pike would repopulate the study reach. <br />Most sampling was done in spring (April-early June) when high water provided quiet, <br />off-channel habitats that were believed to attract northern pike. Sampling was done <br />occasionally in summer (July) and then more intensively in fall (September-early November). <br />Sampling was accomplished by two- (occasionally three-) person crews using the technique <br />deemed most appropriate for the time and location. Occasionally two crews worked together <br />using either one electrofishing boat and a netting crew or two electrofishing boats sampling <br />4 <br />
