WATSED for WINDOWS
Software for Hydrologic and Sediment Response Modeling
The cumulative effects of land management activities on water `quality,
stream channels, and water dependent resources from the introduction of
sediment and changes in quantity and timing of water flow are ever increasing
concerns to land managers. Various regulations require that all Federal
Agencies consider cumulative impacts in the environmental analysis process.
Council of Environmental Quality Regulation 40 CFR 1508.7 defines cumulative
impact as "the impact on the environment which results from the incremental
impact of the action when added to other past, present, and .reasonably
foreseeable future actions regardless of what agency (Federal or non-Federal)
or person undertakes such other actions." Because of the need to
assess the cumulative watershed effects of past, present, and future management
activities on all land ownerships within watersheds in the National Forests
of the Northern Region, the Forest Service has developed WATSED, a computer
model to aid in Forest Service planning efforts and for use by cooperating
agencies and landowners concerned with cumulative watershed effects.
