Floated the Yakima with Dick Lange and a friend on April 17th from below the diversion dam to the KOA. Put on the river at 10:30 am and took off at 5:00 pm. Temperature for the day was 55 degrees with partly sunny skies and minimal wind. Water temperature was cold! Only saw two bugs hatch all day. I seined a riffle and say skwala nymphs, couple of mayfly nymphs, green caddis worms. Caught a total of 5 fish during the day. 3 fish on dropper nymphs and 2 on skwala dries. Fun day but the Skwala hatch is not hot up high on the river yet. May be a little better down lower in the canyon.
