Just did Delta to Whitewater this past week (5/15). Flows were peaking, so going was good. Put in at Delta is a great ramp. Take out at Whitewater isn't ideal, but isn't horrendous either. There isn't room for more than 2/3 boats at the little eddy and backing a trailer down the 30 yards to the "ramp" wasn't an option b/c of clay mud. Folks just need to follow proper take-out etiquette (ie get the F@#$ out of the way asap) and there shouldn't be much problem. There was significant broken window glass at the take-out but we left our cars there for two nights without problems.
Fish were rising all over the place for BWOs, but water was blown for the most part.
All in all a good flat water float with great hiking at Dominguez. And like 1/100th of the people of nearby Ruby/HS.
