CONCLUSION

The sidescan sonar and high-resolution seismic-reflection survey of Lake Mohave shows that little sediment has accumulated on the lake floor since impoundment in 1953. Post-impoundment sediment covers approximately 4 percent of the lake floor. These recent deposits occur either as thin fine-grained patches in the deepest parts of the lake commonly in the lee of promontories, or as coarse-grained mass-transport deposits at the mouths of some tributary washes. Where post-impoundment sediment cover is absent, eolian dunes, roads, channels on alluvial surfaces, trees in overbank areas, and sand waves on the pre-impoundment riverbed are still preserved on the lake floor.
