Definitions for ASCII file of Periodic Water Levels

Date: Date of water-level measurement (year, month,and day).

Time: Time of water-level measurement, in hours and minutes (24-hour clock).

Level: Water level, in feet below land-surface datum (water level above land surface is preceded by a minus (-) sign).

Status: The status of the well when water level was measured. No status is given if the water level represents a static level 
	D, The site was dry (no water level recorded)
	E, The site was flowing recently 
	F, The site was flowing, but the head could not be measured (no water level recorded) 
	G, A nearby site that taps the same aquifer was flowing 
	H, A nearby site that taps the same aquifer had been flowing recently 
	I, Injector site (recharge water being injected into the aquifer) 
	J, Injector site monitor (a nearby site that taps the same aquifer is injecting recharge water) 
	M, The site was plugged 
	N, The measurement was discontinued 
	O, An obstruction was encountered in the well above the water surface (no water level recorded) 
	P, The site was being pumped 
	R, The site had been pumped recently 
	S, A nearby site that taps the same aquifer was being pumped 
	T, A nearby site that taps the same aquifer had been pumped recently 
	V, Foreign substance was present on the surface of the water 
	W, The well was destroyed 
	X, The water level was affected by stage in nearby surface-water site 
	Z, Other conditions that would affect the measured water level

Method: Method used to measure water level. 
	A, Airline measurement 
	B, Analog or graphic recorder 
	C, Calibrated airline measurement 
	E, Estimated 
	F, Transducer
	G, Pressure-gage measurement 
	H, Calibrated pressure-gage measurement 
	L, Interpreted from geophysical logs 
	M, Manometer measurement 
	N, Nonrecording gage
	O, Observed 
	R, Reported, method not known 
	S, Steel-tape measurement 
	T, Electric-tape measurement 
	V, Calibrated electric-tape measurement 
	Z, Other

Accuracy: Water-level accuracy.
	0, Accurate to nearest foot 
	1, Accurate to nearest tenth of a foot 
	2, Accurate to nearest one-hundredth of a foot

Source: Source of the water-level data. 
	A, Reported by another government agency 
	D, Driller’s log or report 
	G, Private geologist, consultant, or university associate 
	L, Depth to water interpreted from geophysical logs by personnel of source agency 
	M, Memory (owner, operator, driller) 
	O, Reported by the owner of the well 
	R, Reported by person other than the owner, driller, or another government agency 
	S, Measured by personnel of reporting agency 
	Z, Other source
