Hydrogeologic data for the Farmington River basin, Connecticut

This report contains hydrologic and geologic data collected and compiled as part of a water resources investigation of the Farmington River basin, Connecticut. The study was made by the U.S. Geological Survey in fiscal cooperation with the Connecticut Department of Environmental Protection. A companion report, Connecticut Water Resources Bulletin No. 29 (in preparation), contains the interpretation of ground-water, quality-of-water, and surfacewater data collected for the study.

Hydrogeologic data for the lower Connecticut River basin, Connecticut

This report contains geologic, ground-water, and miscellaneous data on the quality of surface water collected for a water-resources inventory of the lower Connecticut River basin, Connecticut. The study was made by the U.S. Geological Survey in fiscal cooperation with the Connecticut Department of Environmental Protection. A companion report (Connecticut Water Resources Bulletin No. 31, in preparation) interprets the factual information presented here or otherwise collected for the study.

Estimating earthquake potential

The hazards to life and property from earthquakes can be minimized in three ways. First, structures can be designed and built to resist the effects of earthquakes. Second, the location of structures and human activities can be chosen to avoid or to limit the use of areas known to be subject to serious earthquake hazards. Third, preparations for an earthquake in response to a prediction or warning can reduce the loss of life and damage to property as well as promote a rapid recovery from the disaster. The success of the first two strategies, earthquake engineering and land use planning, depends on being able to reliably estimate the earthquake potential. The key considerations in defining the potential of a region are the location, size, and character of future earthquakes and frequency of their occurrence. Both historic seismicity of the region and the geologic record are considered in evaluating earthquake potential.

Origins and early years of the U.S. Geological Survey

The U.S. Geological Survey was established on March 3, 1879, in the closing hours of the final session of the 45 th Congress. The bill appropriating the money for sundry civil expenses of the Government during fiscal year 1880 was signed by President Rutherford B. Hayes. Included in the bill was the provision for a new agency under the Department of the Interior; it was charged with responsibility for “classification of the public lands, and examination of the geological structure, mineral resources, and products of the national domain.”

Hydrogeologic data for the Upper Housatonic River basin, Connecticut

The upper Housatonic River basin covers an area of about 700 square miles in western Connecticut and includes the towns of Bridgewater, Brookfield, Canaan, Cornwall, Kent, New Fairfield, New Hilford, North Canaan, Salisbury, Sharon, Sherman and Warren and parts of Bethel, Bethlehem, Danbury, Goshen, Litchfield, Morris, Newtown, Norfolk, Ridgefield, Roxbury, Southbury, Torrington and Washington. The U.S. Geological Survey in cooperation with the Connecticut Water Resources Commission conducted a water resources investigation of this basin from July 1966 to November 1968. The interpretive results of this study are published separately in Connecticut Water Resources Bulletin No. 21. Streamflow and water-quality data and measurements of water levels In observation wells collected during the investigative period have been published in the 1967, 1968 and 1969 volumes of the annual series of U.S. Geological Survey reports entitled "Water Resources Data for Connecticut". The remaining significant information, consisting of records of 284 wells and 5 springs, logs of 322 wells and test holes, mechanical analyses of 58 sediment samples of stratified drift and records of 3 pumping tests is contained in this report. The locations of all sites at which hydrogeologic data were collected are shown on plate A (in pocket at back of report). The Information contained on the following pages together with data previously published~ document the companion interpretive report and should facilitate the planned development of water resources at specific localities.
