Mammoth Lakes Mosquito Abatement District



The Mammoth Lakes Mosquito Abatement District (MAD) was formed in 1969 to provide mosquito control to a portion of Mammoth Lakes. The district boundaries include Old Mammoth, part of the Snowcreek development, Valentine Ecological Reserve, and adjacent condominium developments (see Figure 1). The district does not serve this entire area; service is concentrated in the Old Mammoth area, a neighborhood of older, primarily single-family residences. Mammoth Creek bisects the district area, flowing from west to east.


The boundaries of the district fall completely within the boundaries of the Town of Mammoth Lakes. The district area is surrounded to the north and east by condominium developments and to the south and west by recreational land managed by the Inyo National Forest.


Mammoth Lakes is surrounded by recreational lands and open space managed by the Inyo National Forest. Mammoth Mountain Ski Area is northwest of the developed portion of the Town, on Forest Service land within the district’s boundaries. The Lakes Basin, in the southwest portion of the district, is a popular recreation spot for both visitors and residents, with cabins, lodges, and campgrounds. Mammoth Creek, flowing from the Lakes Basin through the town into Long Valley, attracts fishermen.


Wilderness areas surround the town and district to the south and west, and Devil’s Postpile National Monument is located west of the town and district in Madera County. June Lake, Mono Lake, Bodie State Historic Park, and the eastern entrance to Yosemite National Park are located north of Mammoth Lakes. US 395 and SR 203 provide the major access to and through the area. Old Mammoth Road and Lake Mary Road provide secondary access throughout the community. Surface waters in the area include the lakes in the Lakes Basin and Mammoth Creek. Topography in the area is characterized by a relatively flat area in the center of the town, and by steep slopes surrounding the town center. Vegetation throughout the area includes sagebrush scrub, wetland and riparian areas, junipers and pinon pines, and lodgepole pines.


The Mammoth Lakes Mosquito Abatement District Board meets quarterly.
