Description:
Abstract:
Digital shapefile of the riverine cross sections used in the development of the hydraulic model for estimating flooding of the Winooski River was created by the U.S. Geological Survey (USGS) in cooperation with the Federal Emergency Management Agency (FEMA) for a 8.3-mile reach of the Winooski River from about 1,000 feet downstream of the Waterbury-Bolton town line upstream to about 2,000 feet upstream of the Waterbury-Middlesex town line.
Purpose:
The cross section locations used in the development of the hydraulic model for estimating flooding of the Winooski River

Although these data have been used by the U.S. Geological Survey, U.S. Department of the Interior, no warranty expressed or implied is made by the U.S. Geological Survey as to the accuracy of the data. The act of distribution shall not constitute any such warranty, and no responsibility is assumed by the U.S. Geological Survey in the use of this data, software, or related materials. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. The flood boundaries shown were estimated using steady-state hydraulic modeling (assuming unobstructed flow) and a digital elevation model. The hydraulic model reflects the land-cover characteristics and any bridge, dam, levee, or other hydraulic structures existing July 2013. Unique meteorological factors (timing and distribution of storm) could cause actual streamflows along the modeled reach to vary from those assumed during a flood, which may lead to deviations from the water-surface elevations and boundaries shown here. Additional areas may be flooded owing to unanticipated backwater from major tributaries along the main stem or from localized debris- or ice-jams. Inundated areas shown should not be used for navigation, regulatory, permitting, or other legal purposes. The USGS provides these maps as a planning tool but assumes no legal liability or responsibility resulting from the use of this information.
