7 <br />reservoir (6.4 km). There are few large bays or coves in Lake Mohave, <br />and it is best characterized as a "run of the river" reservoir. <br />Small coves are formed in some areas of the basins by the series of <br />desert washes that have been inundated by the reservoir. These washes <br />are major sources of the shoreline alluvial substrates that are washed <br />into the reservoir. Generally larger cobble and gravel substrates are <br />found along shore and finer materials are located in deeper waters. The <br />reservoir has a long north-south fetch and is subject to high winds from <br />the predominately south-southwest direction in summer and <br />north-northeast direction in winter. This can result in severe seasonal <br />wind and wave action (Minckley 1983) particularly in these larger flat <br />basin areas. Water levels fluctuate approximately 5 m annually. <br />Inundated terrestrial vegetation is particularly common in the <br />submerged basin areas during winter and spring when water levels are <br />high. Terrestrial vegetation is typical of that in the Mojave Desert and <br />consists of creosote bush, mesquite (Prosopsis sp.), eriogonum <br />(Eriogonum sp.), salt bush (Atriplex sp.), arroweed (Pluchea sericea), <br />and barrel cactus (Echinocactus polycephalus). Extensive growth of salt <br />cedar (Tamarix sp.), occurs along the shoreline. Large beds of <br />submergent vegetation, Myriophyllum sp., and thin leafed Potomogeton sp. <br />are found along these shorelines after draw-downs during summer months. <br />Climate is arid with an annual precipitation about 8 cm. Mean <br />annual temperature is about 19°C ranging from 45°C in summer to -1°C in <br />winter. <br />In this report, the Six Mile Coves area refers to the area of the <br />Nevada shoreline in the Cottonwood Basin that is located above Hog Farm
