Draft Fmal Completion Report to UDWR for Contract #93-1070, Amendment 3 26 Interpretation and Transfer At USU, the video prints were interpreted and the resultant lines transferred to the base map mylar overlay using a zoom transfer scope (ITS). The interpretation consisted of separating each image into geomorphically- meaningful units. On the video prints, the coloring of the within-channel deposits was indicative of composition and moisture content of the deposit. Relative topographic elevation was interpreted from these data. The mapping unit descriptions are summarized in Table 4. A 10-km subset of the Ouray nursery habitat reach (RM 251 to RM 257.4) was interpreted and digitized. Each individually interpreted video print was transferred onto a mylar overlay of the video base map using the ITS, and the di.fference in the lines between individual video prints was smoothed by eye. The resulting overlay mosaic was then digitized into an ARCIINFO database on a Sun Microsystems Unix platform. The coverage was later referenced using the Lambert conformal conic coordina~s from the Reclamation video base maps. Table 4. Interpreted geomorphic units for video prints. Habitat units are defined in Table 5. Unit Description water Main channel with no visible sand bed. ss Submerged sand visible through the water. This indicates shallow bars but to some extent, is dependent on the clarity of the water. ip Isolated pools. Found at river level, but separated by bar deposits from the main channel. wt Wet sand. Found near flow level, darker than submerged sand with a visible shoreline, particularly apparent during turbid periods when the water is orange/brown and deposits are more gray. ds Dark sand. Usually found near base flow level, within the level of fluctuation; deposited by low summer floods caused by thunderstorms. ws White sand. This sand is deposited at high flow, typically about 1m above base flow. s/v Sand and vegetation. These deposits are higher than ws and are areas have sparse vegetation. veg Vegetated deposits within the channel. These are typically higher deposits stabilized by older vegetation.
