He discussed the terms dry lake ("shallow lakes that dry out occasionally"), playa lake
("the flooded stage of a playa") and sabkha ("coastal saline flat similar in many respects to interior playas").
"The majority of our local drainage occurs via the surface into playa lakes
, shallow depressions in the surface of the ground which become small lakes when filled with rain and storm water runoff."
Two other High Plains water resources, playa lake
water and atmospheric moisture, are of much less direct importance for urban water supply, and are not integrated in municipal conjunctive water use and management plans.
For example, the Uppermost Dethlingen and Hannover Formations (Capitanian-Wuchiapingian according to Schneider et al, 2006) represent an evaporitic playa mud flat environment with associated perennial playa lake
and salt flats.
From this perspective, concentrations of pollutants that enter the playa lake
via stormwater runoff are of interest in assessing the value of lake water for recreational and other potential uses, as well as for subsequent impacts on the underlying groundwater (U.S.

These facilities will use natural salt resources and drainage water of inland basins, similar to the playa lake
basins of the Southern High Plains.
Marshes (wet meadows, prairie potholes, vernal pools, playa lakes
) and swamps (forested swamps such as bottomland hardwoods and shrub swamps such as mangrove swamps) are considered forms of wetland.
These playa lakes
contain brines enriched in salts such as potassium salts.
