Current river observations and forecasts from federal agencies provide local site-specific information at gauge locations. Data from these gauges are essential for developing reliable flood warnings and many other purposes.
A local gauge network, operated by the non-profit Environmental Emergency Services (EES), supplements the information from federal agencies with real-time information about stream, river, and lake levels; precipitation; and other weather conditions. During flood events, conditions are monitored by volunteers to support emergency operations in Chemung, Steuben, and Schuyler Counties.
Flood inundation maps show the areas that are expected to be inundated when the river reaches various levels. This provides a graphical extension of river forecasts by showing where flooding is likely to occur and how deep the water may be. This tool can be used to plan for flood emergencies, as well as for emergency response.
