Description:
Abstract:
Digital shapefile of the study limits of the hydraulic model for estimating flooding of the Winooski River. The hydraulic model 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:
Limit of study for the hydraulic model for estimating flooding of the Winooksi River in Waterbury, Vermont

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 water stages at the USGS streamgaging station 04288040, Winooski River above Crossett Brook at Waterbury, Vermont, 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 inundation 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. Although USGS intends to make this server available 24 hours a day, 7 days a week, timely delivery of data and products from this server through the Internet is not guaranteed. The USGS provides these maps "as-is" for a quick reference, emergency planning tool but assumes no legal liability or responsibility resulting from the use of this information. If this series of flood inundation maps will be used in conjunction with National Weather Service (NWS) river forecasts, the user needs to be aware of additional uncertainties which may be inherent or factored into NWS forecast procedures. The NWS uses river forecast models to estimate the quantity and timing of water flowing through selected river reaches in the United States. These forecast models (1) estimate the amount of runoff generated by a precipitation event, (2) compute how the water will move downstream, and (3) predict the flow and stage (water-surface elevation) for the river at a given location (Advanced Hydrologic Predictions Service forecast point) throughout the forecast period (every 6 hours and 3 to 5 days out in many locations).
