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.

Drought Streamflow Probabilities in Northeast Region mapper

Hydrologic drought streamflow probabilities for July, August, and September are provided as functions of streamflows during the previous October, November, December, January, and February. Probable streamflows are identified 5 to 11 months ahead of their occurrence. This application allows the display and query of these drought streamflow probabilities for Northeast region streams.
