The National Weather Service at Indianapolis announced today that the two Wabash River sites in the immediate Vincennes area have been combined into one. The remaining site is located at the Lincoln Memorial Bridge.
The Weather Bureau established the Vincennes Wabash River gage on February 1, 1917 at the wagon bridge. The Lincoln Memorial Bridge replaced the wagon bridge on September 3, 1933. The National Weather Service (previously the Weather Bureau) has provided flood forecasts for this location since 1917.
The U.S. Geological Survey uses the latest technology to automate and now measure the river height and flow at the Lincoln Memorial Bridge. A radar gage measures the river height, while acoustic Doppler technology determines river flow. River readings are transmitted hourly.
By combining monetary resources with the City of Vincennes, the Louisville Corps of Engineers and the U.S. Geological Survey, stream flow measurements will now be available for the Wabash River at Vincennes for the first time since September 30, 1994. Prior to Doppler technology, stream flow measurements could not be made reliably at the Lincoln Memorial Bridge.
