Estimating Drought Streamflow Probabilities for Virginia Streams

Maximum likelihood logistic regression is used to estimate drought probabilities for selected Virginia rivers and streams. Hydrologic drought streamflow probabilities for summer months are provided as functions of streamflows during the previous winter months. This application allows the display and query of these drought streamflow probabilities for Virginia streams.

North Fork and South Fork Shenandoah River Habitat Maps

The layers within this geodataset describe physical habitat characteristics in the North and South Fork Shenandoah rivers. They represent conditions during summer low-flow periods when canoeing was possible.The data are derived from GPS field surveys and GIS editing to commplete habitat units around islands or river bends.
