Geography of the Lake Havasu Basin

The Lake Havasu Basin, located in the southwestern part of the planning area, is the second smallest basin at 252 square miles.  Geographic features and principal communities are shown on Figure 4.5-1.  The basin is characterized by a valley adjacent to the Colorado River and Lake Havasu, which form the western boundary of the basin, and by lower elevation mountains along the north and eastern basin boundary. Vegetation types include lower Colorado River and Arizona upland Sonoran desertscrub and Mohave desertscrub (see Figure 4.0-9).  Riparian vegetation includes tamarisk and marsh along sections of the Colorado River.

Principal geographic features shown on Figure 4.5-1 are:

  • Chemehuevi Valley running parallel to the Colorado River and Lake Havasu

  • Standard Wash running north to south in the eastern part of the basin

  • Bill Williams Mountains on the southeastern basin boundary

  • Mohave Mountains along the northeastern basin boundary with the highest point in the basin, Crossman Peak at 5,100 feet

  • The lowest point in the basin at approximately 470 feet at the Colorado River
