(NTIS #PB96-172267) ABSTRACT This chapter describes specific procedures that are to be followed by Long Term Resource Monitoring Program (LTRMP) staff when creating aquatic areas coverages. This procedure uses data already created for the land cover/use coverage for the pool. The procedures are divided into several steps: (1) delineation of the main channel, (2) digitizing the main channel and structures, (3) dissolving the land cover data into aquatic and nonaquatic classes, (4) on-screen digitizing and classification, (5) completing the attribute tables photointerpretation, and (6) placing the coverages in the database. The aquatic areas classification is appended. KEYWORDS Aquatic areas, aquatic habitat, river geomorphology, Upper Mississippi River
