Flood inundation depth for a gage height of 3.0 ft at gage 01389534, Peckman River at Ozone Avenue at Verona, New Jersey (pecknj_01)

Resource Abstract:
<p>The basis for these features is U.S. Geological Survey Scientific Investigations Report 2016-5105 Flood-inundation maps
for the Peckman River in the Townships of Verona, Cedar Grove, and Little Falls, and the Borough of Woodland Park, New Jersey,
2014.Digital flood-inundation maps for an approximate 7.5-mile reach of the Peckman River in New Jersey, which extends from
Verona Lake Dam in the Township of Verona downstream through the Township of Cedar Grove and the Township of Little Falls
to the confluence with the Passaic River in the Borough of Woodland Park, were created by the U.S. Geological Survey (USGS)
in cooperation with the New Jersey Department of Environmental Protection. </p> <p>Flood profiles were simulated for
the stream reach by means of a one-dimensional step-backwater model. The model was calibrated using the most current stage-discharge
relations at USGS streamgages on the Peckman River at Ozone Avenue at Verona, New Jersey (station number 01389534) and the
Peckman River at Little Falls, New Jersey (station number 01389550). The hydraulic model was then used to compute eight water-surface
profiles for flood stages at 0.5-foot (ft) intervals ranging from 3.0 ft or near bankfull to 6.5 ft, which is approximately
the highest recorded water level during the period of record (19792014) at USGS streamgage 01389534, Peckman River at Ozone
Avenue at Verona, New Jersey. The simulated water-surface profiles were then combined with a geographic information system
digital elevation model derived from light detection and ranging (lidar) data to delineate the area flooded at each water
level.<br> <br> The availability of these maps along with Internet information regarding current stage from the USGS streamgage
provides emergency management personnel and residents with information, such as estimates of inundation extents, based on
water stage, that is critical for flood response activities such as evacuations and road closures, as well as for post-flood
recovery efforts.</p>

purpose:
This raster represents modeled flood inundation depth of a 7.5 mile reach of the Peckman River from Verona Lake Dam in the
Township of Verona downstream through the Township of Cedar Grove and the Township of Little Falls to the confluence with
the Passaic River in the Borough of Woodland Park. This raster corresponds to a gage height of 3.0 ft at gage 01389534, Peckman
River at Ozone Avenue at Verona, New Jersey, and will be used on the U.S. Geological Survey Flood Inundation Mapper website.
