<br />Study Stations.--Three study stations were selected on Sweet- <br />water Creek, three on the upper and three on the lower South Fork of the <br />White River (Figure 1). Throughout this report, the South Fork of the <br />White River will be referred to only as the South Fork. These stations <br />were permanently staked and adequately described in field notes for sub- <br />sequent remeasurements (Appendix A). The stations were about 500 feet <br />in length with the exception of Station 1. Its length was extended an <br />additional 175 feet to take in a section of Sweetwater Creek suitable <br />for diversion and manipulation of the channel flows. <br />Mapping.--Most stations were surveyed three times during the <br />summer and maps were drafted of the stream at the existing stream dis- <br />charge. To accomplish this, a 500 foot base line was laid out parallel <br />to the stream. At 25 foot intervals, transects were run perpendicular <br />from the base line to the far bank of the stream. Water depths were <br />taken by rod measurements to the nearest tenth-foot at one foot inter- <br />vals a-long the transects. With these controls-the habitat-types of pool <br />riffle,- deep fast, slow shallow, or undercut bank were mapped to scale <br />of 1" equals 10'. The areas of undercut bank were later tabulated with <br />pools. Protruding rocks,. dry gravel bars, and islands were mapped as <br />dry rock. This habitat classification was designed to differentiate be- <br />tween the shelter areas, food-producing areas, and areas unsuitable for <br />trout habitat (slow shallow and dry rock). These maps are on file at <br />the Fisheries Research Center, Fort Collins (see Appendix B for sample <br />on reduced scale). <br />
