Records Collected During Aquifer Tests

In all the aquifer tests, measurements of drawdown below static water level in the pumping well were made by an electric water-level gage. Time was determined by stopwatch. Yield of the wells was measured by means of a Collins flow gage.

Table 10--Aquifer test using well 16-85-81da in Wichita County, made Aug. 23 to Aug. 24, 1952. Measurements were made in the pumped well.
