Maximum likelihood logistic regression (MLLR) is used to estimate drought probabilities for selected Northeast rivers and streams. Winter streamflows are used to estimate the chance of hydrologic drought during summer months. This application allows the display and query of these drought streamflow probabilities for Northeastern streams.
Define the hydrogeology of extensively used (primary) stratified-drift aquifers in upstate NY, and present the information as individual sets of maps at 1:24,000 scale. Each published report describes the hydrogeology of a specific aquifer or segment, and depicts selected hydrogeologic characteristics. Continue the hydrogeologic assessment and mapping of selected principal aquifers in upstate NY.
