Pink and chum salmon spawners noted at site.<br />
Site 15 m long x 7.5 m wide (112.5 m 2 ), Discharge 0.49 m 3 /s for 9.1 m width assessed<br />
Site CF2 was located in Reach 3, approximately 5 m upstream from the head pond (Figure 1).<br />
The site was approximately 96.2 m 2 and exhibited similar boulder boulder-cascade stream<br />
morphology as noted in Reach 3. Substrate and stream habitat covers were also similar to<br />
Reach 2, providing predominantly boulder and cobble habitat cover. Stream width was<br />
approximately 17m at site CF2, with a maximum depth of 1.20 m and mean depth of 0.30 m<br />
observed on September 13. Maximum velocity was measured as 0.77 m/s and mean velocity<br />
was 0.54 m/s.<br />
Discharge at Site CF2 was calculated from data collected at seven points across a<br />
representative site transect, extending approximately 6 m into the stream channel. Stream<br />
depth and swift velocity precluded field crew ability to collect stream discharge data across the<br />
entire stream channel. Discharge at Site CF2 was determined to be 1.11 m 3 /s based on<br />
measurements made September 13, 2006.<br />
Sites CF1 and CF2 both exhibited similar conductivity (22.0 µS/cm) and approximately similar<br />
stream temperatures (9.2°C at Site CF1 and 9.5°C at Site CF2).<br />
