Lake Wyara is a saline playa lake
in a complex of lakes and wetlands in Currawinya National Park (Fig.
our report is not an entry into that debate, but presentation of data on associations and dissociations between black-tailed prairie dogs and small rodents at the ecologically rich areas of playa lakes
(Haukos and Smith, 1992; Smith, 2003).
About 22,000 to 40,000 playa lakes
dot the Southern High Plains, which includes the Texas Panhandle and part of neighboring New Mexico.
The playa lakes
included in this study are located in a 43 county geographical area bordered on the north by the Canadian River and on the east and west by escarpments (Osterkamp & Wood 1987).
As development occurred over the past several years, the playa lakes
have seen increased permanent water surfaces, Keenum continued.
More than 10,000 feet of pipe ranging from 24 to 72 inches in diameter carried stormwater from the 11 playa lakes
to a discharge point near the city's water reclamation plant.
Most local runoff flows to shallow playa lake
But lots of studies document that playa lakes
, prairie potholes and vernal pools--all wetlands that are often less than one-half acre in size--have very significant environmental values.
The authors investigated 20 playa lakes
located within the city of Lubbock, Texas (101 [degrees] 52[minutes] N, 33 [degrees] 35[minutes] W), that remain permanently inundated.
Joint Venture: Phillips cut its teeth on environmental partnerships when it helped create the Playa Lakes

This work was supported by Texas Parks and Wildlife through sales of state waterfowl stamps and through Federal Aid in Wildlife Restoration Act Project W-128-R, the Playa Lakes
Joint Venture through contributions by ConocoPhillips, and the Killgore Research Center at West Texas A&M University.
However, associations of black-tailed prairie dogs with playa lakes
have not been investigated.
