A study of the time-of-travel of solutes in a reach of the Trinity River from Dallas to Trinidad, Texas, was conducted in May and August 1987 using 20% Rhodamine WT dye and fluorometry. Two injections of dye were made--one in each of two subreaches--and tracked at several locations downstream. Discharges on the river ranged from 700 to 1,160 cu ft/sec. Traveltime data are presented with a map of the study reach, dye- concentration plots, and traveltime versus distance plots. The mean velocity of the concentration peak for the upper subreach was 1.18 ft/sec. The mean peak velocity for the lower subreach was 1.02 ft/sec. (USGS)
