Hydrologic data; North Canadian River from Lake Overholser to Lake Eufaula, central Oklahoma

Geohydrology of the alluvial and terrace deposits of the North Canadian River from Oklahoma City to Eufaula Lake, central Oklahoma

“…Maximum thickness of the alluvium penetrated in test drilling is about 50 feet; the average thickness is 30-40 feet (Havens, 1985). No test holes were drilled into the terrace deposits for this study; the terrace in the vicinity of Oklahoma City reportedly has a maximum thickness of about 80 feet (Wood and Burton, 1968).…”

“…Analyses of water samples from the North Canadian River and tributaries were collected at the low-flow and base-flow measuring sites. These data are published in Havens (1985).…”

“…Data for the present project were published as U.S. Geological Survey Open-File Report 84-808, "Hydrologic data: North Canadian River from Lake Overholser to Lake Eufaula, central Oklahoma" (Havens, 1985). This report contains logs of test wells, water-quality data for wells and test holes, hydrographs of water levels in test wells, comparisons of water-level changes and river stages at nearby gaging stations, and a tabulation of low-flow and base-flow measurements on the North Canadian River and tributaries.…”

“…The Quaternary alluvial and terrace deposits consist of sand, silt, clay, and gravel. Sand-size sediments predominate and consist generally of very fine-to medium-grained brown and tan sand, with occasional stringers of coarse-grained sand (Havens, 1985). Terrace deposits "consist mostly of lenticular beds of sand, silt, clay, and gravel, which vary greatly in thickness within short lateral distances" (Wood and Burton, 1968).…”

“…Earlier measurements of the terrace aquifer in the vicinity of Oklahoma City (Wood and Burton, 1968) were combined with measurements of the observed potentiometric surface of the alluvial and terrace aquifer during 1982 (Havens, 1985) to give a head-distribution map of the alluvial and terrace aquifer for 1982 (pi. 2).…”
