Compilation of hydrologic data, Green Creek, Brazos River basin, Texas, 1966
Trigg Twichell
1969, Report
In 1950 the U. S. Soil Conservation Service began construction of floodwater-retarding structures in Texas under authorities granted by the Congress. These authorities provide, where economically feasible, that the program be applied to tributary watersheds of 240,000 acres or less. The usual practice has been to control flood runoff from...
