A fine-grained bed of an ephemeral lake in a desert is also known as a Playa.

A playa (also known as a dry lakebed or alkali flat) is a basin or depression that holds water only temporarily, usually after rain, forming an ephemeral lake. As the water evaporates in the arid conditions, fine-grained sediments (silt and clay) are left behind, forming a smooth, flat, dry surface.

Oasis is a fertile area in a desert with a water source. Drumlin is a glacial landform. Natural levee is a feature of river systems. The description of a temporary lakebed with fine-grained deposits in a desert specifically refers to a playa.
