National Hydrography Dataset (NHD)?
1
3
A framework dataset that includes:
•Hydrographic features for making maps
•A national stream addressing system
2
•A modeling network for navigating
upstream/downstream
•A maintenance infrastructure
Data and information available at
http://nhd.usgs.gov

7. What are NHD Reaches?
Watershed 02050701

1
Watershed 02050701
contains 3 NHD reaches:
- 02050701 000001
- 02050701 000002
- 02050701 000003
3
which provide the
framework for reach
(stream) addresses in
the same manner that
streets do for street
addresses

39. 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

40. 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.

44. 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.
