Routine Effectiveness Evaluations Port Alberni District (TFL 44) Objective The project objective was to conduct routine effectiveness evaluations (REE) at 14 instream restoration sites in Sarita River, 36 sites in South Sarita River, 80 sites in Sabrina Creek and nine sites in Hunter Creek located within TFL 44. In addition, REEs were conducted at six off- channel sites in the Sarita, Klanawa, Clemens and Taylor watersheds.

The project areas can be accessed via PTH 4, branch roads off the Bamfield Road and by water taxi to Henderson Lake. Introduction Instream restoration structures were constructed in the Sarita River watershed (Huu-ay-aht First Nation 2000, Ochman 2002) and off-channel habitat was constructed in Sarita, Klanawa, Taylor (Wright and Associates 1999a&b) and Clemens (Guimond 1999) watersheds. The objectives of these projects were to: • enhance juvenile rearing habitat for coho and steelhead in the Sarita watershed by increasing instream habitat complexity, • enhance spawning and juvenile rearing primarily for coho by establishing off- channel habitat, and • enhance sockeye adult holding, spawning and juvenile rearing capacity by improving off-channel habitat in Clemens Creek. Performance Summary A total of 138 structures in the Sarita watershed were evaluated for physical and biological performance. Across all structures, the pooled mean physical performance objective was 3.1 ± 0.964, whereas the mean biological performance objective was 3.0 ± 0.908. The 138 structures represent five structure categories as follows: revetments (LWD-R, n = 27), lateral jams (LWD-M, n = 81), deflectors (LWD-D, n = 9), riffles (RIFF, n = 4), and single log structure (LWD-1, n = 17). It is interesting to note that single log structures were out performed by lateral jams, deflectors and revetments. A total of six ground water fed channels were evaluated for physical and biological performance. Across all structures, the pooled mean physical performance objective was 3.0 ± 0.577, whereas the mean biological performance objective was 3.286 ± 0.488. Conclusions Based on the results of the REE, all off-channel projects examined appear to be relatively stable and functioning as anticipated or exceeding expectations. The only exception that should receive attention is the alcove pond located at designation M9, Taylor River groundwater channel. During 1999, this pond and connecting channel both were extensively used for rearing and exceeded all expectations for spawning
