Conference Focus

Historically, evaluation of urban land uses and stormwater management facilities has relied, almost totally, on chemical analysis of stormwater runoff entering receiving systems. There is a greater recognition that water quality is only one component of an evaluative process. Receiving systems must also be considered for impacts to the aquatic community in terms of habitat, diversity, and abundance of stream dwelling organisms.

The focus of this conference is to recognize that comprehensively understanding aquatic ecosystems is a necessary component of any overall effort to evaluate watershed health related to our use of watersheds. An ecological survey can function as a preliminary screening tool to determine whether adverse impacts are occurring within a watershed, and whether those impacts are related to hydrologic, morphological and riparian, or water quality factors, or a combination.

The results of the ecological evaluation would determine whether more detailed monitoring or analysis is necessary. In addition, ecological evaluations can be a valuable tool in assessment of stormwater management program effectiveness, and can serve as an alternative monitoring approach to traditional chemical monitoring to evaluate the relative health of receiving systems. Ecological considerations represent another tool that needs to be considered when evaluating the impact of watershed activities or gauging the effectiveness of protection strategies.

This conference will assist in establishing and defining relationships that may exist between traditional, emerging, and possible future approaches to conducting watershed analyses.
