Map showing how the potentiometric surface of the Magothy Aquifer of August 1980 differed from the potentiometric surface of September 1977, in southern Maryland
Frederick K. Mack Jr., J. C. Wheeler, Stephen E. Curtin
1982, Open-File Report 81-631
The map is based on the differences between two sets of water-level measurements made in 65 observation wells. One set was made in 1977, a relatively dry year, and the other set was made in 1980, another relatively dry year. The map shows that the potentiometric surface was higher in...

1982, Open-File Report 82-915
This map presents the potentiometric surface of the Floridan aquifer in the St. Johns River Water Management District and vicinity for May 1982. The Floridan aquifer is the principal source of potable water in the area. Water-level measurements were made on approximately 1,000 wells and on several springs. The potentiometric...
Flood profiles in the Calapooya Creek basin, Oregon
John Friday
1982, Open-File Report 82-439
Water-surface profiles were computed for a 19.4-mile reach of Calapooya Creek in Douglas County, Oregon. The data will enable the county to evaluate flood hazards in the floodprone areas in the reach. Profiles for floods having recurrence intervals of 2, 10, 50, 100, and 500 years are shown in graphic...
Base flow of streams on Long Island, New York
Richard J. Reynolds
1982, Water-Resources Investigations Report 81-48
On Long Island, base flow under nonurbanized conditions constitutes 90 to 95% of total stream discharge. Base-flow data from 19 continuously gaged streams are presented as monthly mean and annual mean discharge for water years 1960-75, which includes the 1962-66 drought. The data were derived by hydrograph-separation procedures that isolate...
