A dry lake is either a basin or depression that formerly contained a standing surface water body, which disappeared when evaporation processes exceeded recharge. If the floor of a dry lake is covered by deposits of alkaline compounds, it is known as an alkali flat. If the total annual evaporation rate exceeds the total annual inflow, the depression will eventually become dry again, forming a dry lake. In deserts, a dry lake may be found in an area ringed by bajadas. Damp, dampish, moist.
