significant decline (Table 8). Speckled dace relative abundance in seine samples was low and similar in the two study periods in Browns Park and LD1 reaches, but declined rather dramatically in Lodore Canyon reaches LD2 to LD4 in 2002 to 2004. Speckled dace was moderately abundant in Whirlpool Canyon and Island-Rainbow Park reaches in 2002 to 2004, but was uncommon in Island-Rainbow Park in 1994 to 1996. Flannelmouth sucker was found in all study reaches. Abundance of adults increased slightly in a downstream direction while young fish in seine samples declined in abundance downstream (Fig. 19). Flannelmouth sucker relative abundance and CPUE in electrofishing samples declined by nearly 40% in all Lodore Canyon reaches in 2002 to 2004, compared to the 1994 to 1996 period; CPUE data demonstrated a significant decline. Flannelmouth sucker typically represented 20 to 25% of electrofishing samples in all Lodore and Whirlpool Canyon reaches. Relative abundance of flannelmouth sucker in seine samples was dramatically reduced in Browns Park and Lodore Canyon reaches 1 to 3 in the 2002 to 2004 period. Relative abundance in LD4 and Island-Rainbow Park was similar and relatively low in the two periods. Flannelmouth sucker in the 451- to 500-mm TL size class from electrofishing samples dominated collections in all study reaches and in both study periods (Fig. 20). Fewer small (< 400 mm TL) flannelmouth suckers were found in samples in Lodore Canyon in the recent period compared to 1994 to 1996, particularly in reaches LDI to LD3. Relatively large numbers of small flannelmouth sucker were present in the upper portions of Whirlpool Canyon, with many found in Echo and Mitten parks. Bluehead sucker was also distributed throughout the study area, and similar to flannelmouth sucker, large juveniles and adults in electrofishing samples increased in abundance downstream and relative abundance of small individuals in seine samples declined downstream (Fig. 21). Bluehead sucker relative abundance and, particularly, CPUE in electrofishing samples declined in all Lodore Canyon reaches in 2002 to 2004 compared to 1994 to 1996; the decline in CPUE for bluehead sucker was significant. Bluehead sucker abundance ranged from 5% to 10% of the electrofishing sample in upper Lodore Canyon in both sampling periods and represented 25% of the electrofishing sample in lower Whirlpool Canyon in 2002 to 2004.
