The but an early thaw opened a major part of the river was completely frozen by December 1971, creek channel in February 1972. DESCRIPTION OF SAMPLING SITES Sampling sites were chosen to represent a variet)- of different ecological niches along the drainage. Seven sites were estabhshed for quan- titative study, which were numbered beginning downstream at Lawrence and proceeding up Huntington Canyon to the mouth of Bear Can- yon (Fig. 13). Tliis was also the general order followed during sampling. Lawrence (Site 1) This site is located on Huntington Creek miles southeast of Huntington, Emery County, Utah, and miles east of Lawrence, Emery Countv', Utah. It is approximately nine miles below the main diversion dam on Huntington Creek and was established to monitor effects of agricultural drainage and increased dissolved minerals on the algal flora. The actual sampling site was located in a pasture through which the creek meandered near the intersection of Hun- tington Creek and a road leading to the San Rafael Swell (Fig. 14). The average width of the creek at this locahty was 22 feet during the spring flood and 15 feet during low water periods. Average water depths during the same periods were 22 and 13 inches, respectively. This site included slow-flowing deep water and. lli-1 A-r ^;.*Jft Fig 14.

A sharp, eroded bank character- ized the west side of the stream, whereas the east bank sloped gradually into a pasture. Popu- lus angustifolia, Tamarix pentandra, Chrijsotham- nus tmuseosus, and Artemesia tridentata oc- curred along the banks throughout this area. The stream bed here consisted mo
