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 Figure 2  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. Figure 1
