3. avoid or minimize long-term O&M:
4, avoid or minimize adverse effects on adjacent landowners:
5, avoid or minimize adverse effects on the geomorphology of the
main river channel,

IV, Study Goals. Objectives, End Product:

Goal:

To restore floodplain habitats in a manner that will benefit
endangered fishes, minimize potential adverse effects, and be cost-
effective.

Objectives:

1. To determine bankful flood flows. witll and without excavation:
2, To determine area of inundation as a function of flow, with and
without excavation:
3. To compare historical ,versus existing frequency, duration, and
timing of flood flows, with and without excavation:
4. To characterize pre-restoration baseline channel and site
morphology, and post-restoration morphology:
5, To develop design options for enhancing floodability;
6, To oversee construction:
7, To monitor/evaluate results,

End Products:

Reports of results of each year's surveying, site design and
engineering activities, including stage-discharge relationships:
pre- and post-restoration surface area of inundation as a function
of flow: cross-sectional profiles: and topo maps with design
enhancements,

V, Study Area

Sites and segments will be located on the Green, Colorado, and
Gunnison rivers,

VI, Study Methods/Approach

To determine area of inundation versus flow relationships, surveys
are conducted on candidate sites. the river channel, and water
