Elevation-based NHD Catchments




Based upon the integration
of the:

NHD

National Elevation
Dataset (NED)

Watershed Boundary
Dataset (WBD)
Catchment attributes:

Precipitation

Temperature





Catchments for every NHD reach to tie overland flow to the
network
Enhance NHD with elevation-derived attributes such as slope
Improved velocity estimates based upon new Time of Travel
database
Estimate stream flow volume (mean annual) and velocity Enable

Assessing Recovery Potential
of Impaired Waters





Joint OW/ORD project
Recovery potential: the
likelihood of an impaired water
to reattain Water Quality
Standards, given its ecological
capacity to regain lost functions,
its exposure to stressors, and its
social context.
Opportunity to consider
landscape factors related to
recovery potential within
drainage areas and stream
corridors, using GIS

Assessing Recovery Potential
of Impaired Waters (cont’d)
Some Implications of this Project:





Over 800 impaired (303d-listed) streams in
Illinois, yet their exact watersheds are not
delineated; this stumbling block prevents
rapid, statewide GIS assessment in routine
water program planning.
There are tens of thousands of similar
waters nationally.
Availability of good drainage area
delineations/tools removes an obstacle to
statewide comparative spatial assessments
such as recovery potential screening.

Endangered Species: An Example Potential Use of
NHD in Pesticide Risk Assessments
The Office of Pesticide Programs is exploring the use of the NHD and value-added
attributes in a variety of applications related to pesticide risk assessments.
 In this example, NHD navigation tools are combined with the NLCD and NHD
catchments (Thiessen-based) to estimate the direct and indirect effects of agricultural
pesticide use on endangered aquatic species.
 Figure 1 shows Percent Cropped Area (PCA) calculated for each NHD catchment.
 Figure 2 shows NHD stream segments rated based on measurements of agricultural
intensity. Red represents direct affects, and yellow, the indirect effects of agricultural
pesticide use.

Regressions on Watershed
Attributes) water quality models
based upon Reach File Version 1
(RF1) 1:500,00-scale
Success of EPA-funded NHDbased New England SPARROW
model (at right) has motivated
plan to conduct similar modeling
for several USGS NAWQA study
areas during 05/06

USGS StreamStats
 Web application StreamStats that greatly

reduces the time needed to estimate
streamflow statistics for ungaged sites and
to make published streamflow statistics for
USGS data-collection stations easily
accessible
 Based upon state-specific regression
equations
 Supports TMDLs
