protected. The use of jetties or hard-poin1:s could be adopted, but this method can also involve significant expense and would be an experimental solution requiring continual adjustment as the situation demands. If the lirr its of 'the existing and his.toric channel bed are not encroached, it may be desirabll, to provide protection by J:::iotechnical bank stabilization only. Such a solution is inexpensive, and if high flows do not injure the stabilization J:::efore i't has time to take hold, it could provide sufficient pro'tection for a relatively low-cost park feature such as the nature trail. Gunnison River, Upstream of Confluence: A bend exists in the river at about station 33500, and active bank erosion occurs on the concave (right) side. The overbank in this area contains numerous established trees which provide habitat for eagles and other vdldlife. As erosion of the right bank continues, the habitat is threatened. Some trees have already been damaged by the erosion. Trees which may be washed into thE~ river also pose a threat to other areas as they can deflect flows toward vulnerable banks. One structural solution would consist of fill material placed to the riverside of the bank on a flat slope of about 1 vertical to 3 horizontal, armored with riprap. In addition, a pilot channel across the convex side of the river channel would provide relief and diversion during construction. The riprap would require a filter layer, and the armoring should extend from beyond the active erosion on the upstream end to a point beyond the conf1uence with the Uncompahgre River. . An alternative structural solu.tion cou.1d include placement of hard-points at intervals along' the concave bank. The hard-points would be experimenta1 and subject to modification to achieve the desired effect. Submerged grade stabilization structures 'to slow velocities at the erosion area would be sub:lect to problems with large amounts of suspended solids typical of the Gunnison River, and lack of a reliable armor layer to support the structure. Nonstructural solutions such as biotechnical methods and anchored tree deflectors along the bank. could be utilized for low cost protection. Gunnison River, Downstream of Confluence: This is the reach of the river where the new sewage treatment plant has been sited at about stat:ion 27300, about a mile downstream from the confluence. During and after the 1984 floodflows, the right bank was stabilized with riprap 27
