USGS Study Confirms U.S. Amphibian Populations Declining at Precipitous Rates

Ottawa, Ohio is now better prepared to protect lives and property because of a collaborative early flood-warning project put in place by the U.S. Geological Survey, Village of Ottawa, Natural Resources Conservation Service, and National Weather Service (NWS). The unprecedented damage and economic losses from the August 2007 flood in Ottawa, Ohio, prompted the village to seek means to reduce flood damages. The USGS developed interactive flood-inundation maps of the Blanchard River in Ottawa and a flood-warning network, consisting of three USGS streamgages that monitor water levels and streamflow. The USGS upgraded one streamgage and added two new streamgages, which are used by emergency managers to make informed decisions when flooding is imminent. The inundation maps correspond to the NWS flood-warning levels and show areas that would be underwater at various river levels.
