We rode north of Martinez actually in between Walter's Camp and Cibola/Palo Verde area. The water level was decent for this time of year; however, I did hit an unexposed sandbar on Friday evening (which wasn't fun). Water temp was a little on the chilly side once you jumped in (probably in the high 60's low 70's range). The worst part was the wind came up in the morning all weekend and pretty much was blown out all day. Here is a pretty good link to a water report for the lower CO.
