Ivie Reservoir, 24.0 mi downstream from Concho River, and at mile 604.8.
DRAINAGE AREA - 24,193 mi² of which 11,391 mi² probably is noncontributing.
REVISIONS HISTORY - WDR TX-81-3: Drainage area.
PERIOD OF RECORD - Mar. 1968 to current year. Prior to Oct. 1970, published as "at Stacy". PERIOD OF RECORD, Water-Quality.-- CHEMICAL DATA: Apr. 1968 to July 1994. BIOCHEMICAL DATA: Apr. 1968 to Oct. 1977. BIOLOGICAL DATA: Oct. 1974 to Oct. 1977. PESTICIDE DATA: Apr. 1975 to Aug. 1977. RADIOCHEMICAL DATA: Jan. 1981 to Feb. 1981. SEDIMENT DATA: Oct. 1974 to Oct. 1977. PERIOD OF DAILY RECORD, Water-Quality.-- SPECIFIC CONDUCTANCE: Apr. 1968 to Sept. 1994. WATER TEMPERATURE: Apr. 1968 to Sept. 1994.
GAGE - Water-stage recorder. Datum of gage is 1,394.66 ft above NGVD of 1929 (Texas Department of Transportation bridge plans). Satellite telemeter at station.
REMARKS - Since installation of gage in Mar. 1968, at least 10% of contributing drainage area has been regulated by upstream reservoirs, and since Mar. 15, 1990, flow completely regulated by O.H. Ivie Reservoir (station 08136600), 10.5 mi upstream. There are many diversions above station for irrigation, municipal, and oil field operations. Wastewater effluent is returned to the river from numerous wastewater plants above station. At times flow may be slightly affected by discharge from the flood-detention pools of 42 floodwater-retarding structures with a combined detention capacity of 56,730 acre-ft. These structures control runoff from 277 mi² above this station. No flow at times. Some records listed in the period of record for may not be available electronically.
EXTREMES OUTSIDE PERIOD OF RECORD - Maximum discharge since at least 1882, 356,000 ft³/s, Sept. 18, 1936, gage height, 64.59 ft, by slope-area measurement of peak flow. The flood of Sept. 18, 1936, was 4 ft higher than the 1906 flood and 7 to 8 ft higher than the 1882 flood, from information by local resident.
