Evaluation of the Federal-State Cooperative observation well network in upstate New York, 1995-97

The U.S. Geological Survey?s Federal-State
cooperative observation well network in upstate New
York was evaluated in terms of areal coverage,
objectives, and short- and long-term expansion plans.
This report presents a history of the observation well
network in upstate New York and depicts, on maps,
the distribution of observation wells with respect to
climatic regions, physiographic regions, and aquifer
type (bedrock, till, and stratified drift) within New
York State. It also describes siting criteria for observation
wells, outlines the objectives of three types of
observation well subnetworks, and offers suggestions
for short- and long-term improvements of the current
network. Two appendixes contain (1) a table of
selected well data, and (2) hydrographs and boxplots
that show median monthly water levels and monthly
percentile statistics for water levels in the 46 observation
wells.
