Columbia-North Pacific Region Comprehensive Framework Study of Water and Related Lands. Appendix VIII. Land Measures and Watershed Protection. Volume 1. Subregions 1-5.

摘要

The Land Measures and Watershed Protection Appendix shows current and projected watershed conditions, as affected by use of land and water resources, and presents requirements for improving and protecting the watershed through a combination of management practices, land treatment, and structural measures. The discussions are oriented around the four major land use and cover areas, cropland, forest land, rangeland, and other land, for each subregion. Measures and practices discussed in the appendix are primarily associated with water quality and use, conservation, irrigation, soil erosion, and drainage. Structures are primarily designed for flood protection, water quality control, and water use development.
