Water resources data for Maine, water year 1976

Water resources data for the 1976 water year for Maine consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water-levels and water quality of wells. This report contains discharge records for 66 gaging stations; stage only records for 2 gaging stations; contents for 17 lakes and reservoirs; water quality for 13 gaging stations and 22 wells; and water levels for 17 observation wells. Additional water data were collected at various sites, not part of the systematic data collection program, and are published as miscellaneous measurements. These data represent that part of the National Water Data System operated by the U.S. Geological Survey and cooperating State and Federal agencies.

Limnological data report for the Maine Department of Environmental Protection: U.S. Geological Survey cooperative lake studies project

The report contains physical, chemical, and biological information collected on 43 Maine lakes during the 1975 calendar year. Methods for the collection and analysis of the hydrologic data are outlined. Physical characteristics listed include drainage area, surface area, surface elevation, volume, maximum depth, mean depth, epilimnion depth, epilimnion volume, and length of shoreline. Water-quality analysis are listed or up to 27 parameters of the lake-sample sites and 5 parameters on flowing tributaries. Biological analyses include phyto-plankton data for 4 of the study lakes, zooplankton data for 4 of the study lakes, benthic macroinvertebrate data for 25 of the study lakes, and bacterial data for lake tributaries.

Ground water favorability and surficial geology of the Portland area, Maine

This hydrologic atlas describes the surficial geology and groundwater resources of about 240 square miles in Cumberland County, Maine. The most productive aquifers are outwash and ice-contact deposits. Their locations and the most favorable areas for obtaining large yields from them are indicated on the map. The largest reported yield from a well in unconsolidated deposits is 100 gpm, but it is likely that in places as much as 500 gpm can be obtained from properly located and developed wells. Ground water is available to drilled wells in bedrock in sufficient quantity for domestic use. The average yield from bedrock wells is 11 gpm, the median yield is 5 gpm, and the maximum reported yield is 150 gpm. The quality of the water is generally good, although brackish or salty water is obtained by some wells on the coast. (Woodard-USGS)

Ground-water favorability and surficial geology of the Windham-Freeport area, Maine

This report is one of a series describing the geologic and hydrologic conditions governing the occurrence of ground water in Maine. It is a product of the cooperative program of water-resources investigations between the U.S. Geological Survey and the State of Maine Public Utilities Commission. (See index map.) These reports are intended to provide information for the use of those engaged in water- or land-resources planning or development, and particularly for those wishing to develop water supplies large enough for public, industrial, or commercial use. The magnitude of yields that might be obtained from properly located and constructed wells is indicated by the map showing surficial geology and ground-water favorability (figs. 2, 2a). This map gives a generalized interpretation of observed geologic and hydrologic data; it provides a basis for guiding detailed exploration for ground water but does not eliminate the need for such exploration.

Summer behavior of adult radio-equipped woodcock in central Maine

The behavior of 26 adult American woodcock ( Philohela minor ) was studied in central Maine during the summers of 1971-73 using radiotelemetry. Adults used diurnal covers and nocturnal sites that were similar to those previously recorded for immature woodcock. The adults, however, were more active during the daylight hours and moved to nocturnal sites later in the evening. Adult woodcock seemed to be less susceptible than immatures to capture by banding crews at night, because adults walked more often between diurnal and nocturnal sites and remained close to the brushy edges at night. Adult birds occupied a smaller composite summer range than the immatures, did not move as far from their capture sites dunng the observation penods, and traveled shorter distances between diurnal and nocturnal sites.

Water resources data for Maine, water year 1974

Water resources data for the 1974 water year for Maine including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, records of water-quality data on the chemical and physical characteristics of surface- and ground-water, and records of ground-water levels in index wells are given in this report. In Part 1, records are included for 63 gaging stations, of which 62 are streamflow discharge stations, and 1 is a lake station; also are included records for 22 crest-stage partial-record stations, and 14 miscellaneous sites. In Part 2, water quality data on chemical, physical, and biological characteristics of surface and ground water were collected from designated sampling sites at predetermined intervals such as once daily, weekly, monthly, or less frequently, and at some sites data were recorded on punched paper tape at 60minute intervals. Records are given for 38 sampling stations of which 11 are continuous record stations, and 27 are miscellaneous sites. Records of chemical analyses are also given for 21 ground-water sites. In Part 3, water level data are shown for 11 ground-water wells. Locations of surface-water stations, water-quality stations, and ground-water wells are shown in figure 2. A few pertinent stations in bordering States and Provinces are also included in this report. The records were collected and computed by the Water Resources Division of the U.S. Geological Survey under the direction of G. S. Hayes, District Chief, succeeded by C. R. Wagner. These data represent that portion of the National Water Data System collected by the U.S. Geological Survey and cooperating State and Federal agencies in Maine.

Search for blood protozoans in the American woodcock

Smears were prepared from heart blood of 55 woodcock collected in central Maine between spring and fall, 1972 and 1973. Peripheral blood taken from the wings of 41 of these birds also was examined. Examination of stained films revealed no infected blood cells. Samples of heart blood from 35 of the 41 woodcock were injected into young ducks, quail, and a gull. Plasmodia were not seen in inoculated birds.

Comparison of fission-track, K-Ar, and Rb-Sr radiometric age determinations from some granite plutons in Maine

Fission-track ages have been determined on eight apatite and four sphene concentrates separated from plutonic rocks in Maine. K-Ar and Rb-Sr ages for some of these rocks were previously published. In northeastern Maine the whole-rock Rb-Sr, biotite K-Ar, and apatite fission-track ages are concordant at 400-420 million years, whereas in south-central Maine the apatite fission-track age is 150 m.y. and the biotite K-Ar age is about 250 m.y. At intermediate positions along the traverse the whole-rock Rb-Sr, biotite K-Ar, and sphene fission-track ages agree fairly well in the range 390-325 m.y., but the apatite fission-track ages are all about 100 m.y. younger. This pattern is consistent with the hypothesis of burial metamorphism and uplift as proposed in 1970 by Zartman, Hurley, Krueger, and Giletti to explain the abundance of Permian K-Ar ages in central New England.
