prominent thalweg across this transect which was a slow run across a riffle. Transect No. 14 (Appendix; Figure G.9.) This transect was located at RM 1.8, 1.2 miles downstream of the Redlands Diversion Dam. This transect extended approximately 420 feet across the primary channel at a 60° angle to the channel . The mean and maximum water depth was 0.6- and 1.2 feet, respectively, when the flow was 276 cfs. There was a slight thalweg near river left (west bank). Twenty-six of the 179 water depth observations (15X) exceeded 1 foot (Appendix; Table G.4.). Most of the habitat at this transect could be classified as a riffle; the thalweg portion being a slow run. Transect No. 19A (Appendix; Figure G.10.) This transect was located at RM 1.4, 1.6 miles downstream of the Redlands Diversion Dam, approximately 600 feet downstream of the former Black Bridge. The width of the wetted channel was 190 feet and the transect was perpendicular to the primary channel. The mean and maximum water depth was 0.7 and 1.1 feet, respectively, when the flow was 264 cfs and only 5% of the wetted channel width exceeded 1 foot (Appendix; Table G.4.). The habitat at this transect could be classified as a slow run. There was not a prominent thalweg across this transect. Transect No. 1961 & 19B2 (Appendix; Figures G.11. and G.12.) This transect was located immediately downstream of Transect 19A at RM 1.4. Transects were conducted at this site on two different dates, 2 and 3 August. On both days, the transect extended 200 feet across the primary channel at a 45° angle. Flows on both days were similar--268 and 266 cfs; hence the mean and maximum water depth on both days were identical, 0.5 and 1.1 feet, respectively. However, the number of water depths that exceeded 1 foot were greater on 3 August (10 versus 4). The habitat at this transect at this flow was classified as a slow run/riffle. Transect No. 20 (Appendix; Figure G.13.) This transect was located at RM 1.4, immediately downstream of Transect 19B. This transect extended approximately 184 feet across the primary channel at a 45° angle. The mean and maximum water depth was 0.6 and 1.0 feet, respectively, when the flow was 266 cfs. No water depth exceeded 1 foot across this transect during this flow. The habitat at this transect was a slow run across a riffle. Summary of Transect Data Three of the seven FWS transects, 9, 19, and 20, within the 2.3-mile reach had critically shallow water depths less than 300 cfs. The most critical periods were during late-July and early-August 1994 when flows were 250-276 cfs. At these flows, the actual measured mean and maximum depth at transect 9 and 19 was 0.4 and 0.8 and 0.5 and 1.1 feet, respectively (Appendix; Table G.4.). At 300 cfs, the predicted mean and maximum depth at transect 9 and 19 was 0.5 and 1.2 25
