Unusual drought conditions in the summer of 1948 led the irrigators in the lower Brazos River Valley to request releases from Possum Kingdom Reservoir primarily for the irrigation of rice.
The purpose of this study is to determine the time of travel. The first release is identified as that passing the Palo Pinto gage, 20 miles downstream from the reservoir, from August 9 to 16, 1948; the second release is that from August 16 to 30; and the third release is that from August 30 to September 6.
