the climatic conditions that cause glaciation had an indirect effect on arid and semiarid regions far removed from the large ice sheets. the increased precipitation that fed the glaciers also increased the runoff of major rivers and intermittent streams, resulting in the growth and development of large pluvial lakes. most pluvial lakes developed in relatively arid regions where there typically was insufficient rain to establish a drainage system leading to the sea. instead, stream runoff flowed into closed basins and formed playa lakes. with increased rainfall, the playa lakes enlarged and overflowed. pluvial lakes were most extensive during glacial periods. during interglacial stages, with less rain, the pluvial lakes shrank to form small salt flats.
