tributary flow detention structures, debris
basins, and erosion control structures where
appropriate. In cases where tributary
improvements are not practical, either physically
or economically, a mainstream dredging
maintenance program should be established.
Consideration of the effects of these acti vi ties
on fish and wildlife resources should be included
on project by project basis. However, such
consideration should not impair the undertaking
of emergency actions.

(B)

Establish bank erosion and protection guidelines
for private lands and maintain an active
assistance and advisory program with local Flood
Plain Administrators.

(C)

Conduct a comprehensive assessment of needs for
river bank erosion control and protection, and
channel improvement and training structures for
the Floodway elevation flow, and establish a
priority program of implementation for needed
improvements.

.

(D) Develop, in conjunction with the Corps of
Engineers, a comprehensive long-term program to
provide for the maintenance of the Floodway that
provides for coordination and the division of
responsibilities between federal, state, tribal,
and local enti ties.

(E) As part of its proposed Lower Colorado River
Vegetation Management Study, the Bureau should
recommend and implement vegetation management
practices to help maintain the Floodway channel
capacity. The recommended vegetation management
practices should provide for fish, wildlife, and
recreation opportunities that are compatible with
the operation of the Floodway.

(F) Continue to maintain river channel banks for
undeveloped areas along the river and the policy
of allowing, with prior approval, private use of
rock riprap and quarry wastes for maintenance of
existing armored river banks for developed and
occupied lands, inasmuch as there are no other
reasonably accessible sources of suitable rock.

(G) Construct bench marks at river mile markers to
denote the Floodway boundary elevation.
