" <br /> <br />2 <br /> <br />6. <br /> <br />Riverscape - Next to water quality,: t' <br />lands adjacent to the'river) is probably thl' most' important element <br />of a scenic waterway. The vegetation types and wildlife species <br />sighted (or that there is merely a chance to sight) play an important <br />role in the overall experience. Therefore, the less developed the <br />banks are, the better. However, some types of development do not <br />necessarily detract from, and may even enhance the experience. For <br />example, in many cases, scattered summer homes, ranches, and farms <br />are completely compatible with a scenic waterway. (In other words, <br />the extent of development and the ~ of development are the major <br />criteria. ) <br /> <br />FOR DISCUSSIOr~. PURPOSES ONLY <br /> <br />7. Relative Threat of Channelization and Impoundments - Those rivers and <br />streams which otherwise meet the criter~a for inclusion in the system <br />,that are under threat of pollution, ' channelization, impoundment, or <br />other types of development shoe1d be given immediate attention. There <br />won't be a second chance to evaluate their free-flowing va1~es as <br />,th~re will be for other watercourses not proposed for study at this <br />time. <br /> <br />I <br /> <br />""-= <br /> <br />8. LenRth - The length of the waterway is important to the overa11~ <br />experience. Anything less than about 10 miles is not long enough ~o <br />provide a true scenic waterway experience. Also, a watercourse of, less <br />than the above mentioned length may be extremely hard to preserve and <br />protect as a waterway unit. <br /> <br />Too long a length of river segment should also be avoided. Extremely <br />long segments of rivers (more than' about 200 miles) would be difficult <br />to manage, especia11y.when they cross political boundaries. However, <br />the length of the river segment to be protected should generally be a <br />function of the values of the river. <br /> <br />r <br /> <br />) <br /> <br />9. Diversity of Scenic Character and Water Type <br /> <br />a. This region is a land of contrast. The waterways also reflect this <br />contrast, having a range from the desert environment of the . <br />Southwest to the mountains environment of the Rockies" Rivers to <br />be selected should represent the best of each region. However, it <br />should be recognized that the best in each region may not be good <br />enough for the national-system. <br /> <br />b. Waterways having a variety of scenic land forms should also receive <br />high priority. A waterway having bluffs and cliffs mixed periodi- <br />cally with forests and 'meadows are prime candidates for scenic <br />waterway study as they provide a more varied experience to the <br />waterway user. <br /> <br />c. A mixbure of quiet stretches and rapid stretches adds excitement <br />to the waterway experience. Therefore, rivers with a variety of <br />water types should also receive high priority. <br /> <br />I <br />I <br />I <br />I <br />.\ <br />" <br />
