Various Water Quality Parameters From Arizona Canal @ Cholla WTP
Samples collected on 1/15/98 were taken just after dredging had occured and the canal was almost dry. Only a small amount of water was flowing over some very thick, shiny, black sediment. All data from this date are not indicative of normal canal conditions.
Unable to get to site on 2/25/98 due to deep mud making access road impassable
