. Brigham Young University science bulletin. Biology -- Periodicals. 20 habitats. Tlio stream here was bordered by a broad flood plain and averaged about 2 feet deep and 55 feet wide at spring flood. During low water the riffle area became exposed when the current was limited to a narrow channel. The average width during this period was 11 feet and the depth 1 foot. The pool at this site collected sediment and exliibited a deep accumu- lation of silt. The bottom over much of the rest of the stream, especially in the riffle, was cov- ered with small stones. Willows (Salix sp.) and cottonwoods (Populus angtistijolia) were abun- dant on the banks, and a large thicket of Rus- sian Olive (Eleagnus angiistifolia) was present (Fig. 17). Leaves from these trees contributed to the detritus in the stream during the fall months, and the trees were responsible for some shading throughout the year, particularly in the spring and summer. Tie Fork Pond (Site 5) This site is a small shallow pond located at the mouth of Tie Fork Canyon at 7,300 feet ele- vation, six miles upstream from the generating station (Fig. 18). Tliis pond is fed by drainage and seepage from the surrounding hillsides and in turn drains into Huntington Creek via a culvert. This site was established to provide infonnation concerning the composition and seasonal fluctua- tions of algal populations characteristic of some of the ponds and backwaters occurring along the creek drainage. Heavy growths of Potomo- geten, Cham, and filamentous algae dominated the vegetation in this pond during the summer. Bbicham Young University .Science Bulletin.
