Flow: 65 cfs from the dam (Arkansas River Above Pueblo Gauge)
Water Temp: 58F from the dam
Clarity: 12 – 18″ and Chalky due to lake turnover
Hatches: Midge, Tricos, BWO’s with some Caddis and Aquatic Moths
Consistently colder weather this past week has start lake turnover on the reservoir. Water temperatures from the dam are now trending down and staying in the prime range of 48 – 58 F throughout the tailwater. As water temps continue to drop, blue-winged olive mayfly hatches will become more consistent, intense, and longer in duration. We usually see strong, consistent BWO hatches by late October and extending well into December. Until then, expect hatches to remain varied with a mix of tricos, caddis, aquatic moths and midge, in addition to the ever increasing BWO’s.
Along with the cooler water temperatures, lake turnover also brings with it a temporary reduction in water clarity as fine sediment gets stirred up in the reservoir as the water column mixes. This drop in visibility certainly limits sight fishing opportunities and to a lessor extent, surface feeding, but it also has some benefits. The stained water allows for the use of stronger tippet and also gives fish a sense of protection, making them less likely to spook.

ARKANSAS RIVER – CANON CITY TO BUENA VISTA
Flow: 200 cfs at Wellsville
Water Temp: Buena Vista to Wellsville 38-48F, downstream of Wellsville 40-50F
Clarity: Good above Wellsville
Hatches: Blue Winged Olives (BWOs) and Midge
BWO’s are hatching consistently throughout Bighorn Sheep Canyon but the recent cold spell dropped water temperatures drastically and put the fish in a bit of a funk. Slightly warmer, and consistently sunny weather is forecast the week ahead and should have a stabilizing effect on on water temps. Nymphing has been the most effective and egg patterns are becoming increasingly effective in addition to tiny BWO and midge imitations.
