Basic Playa Monitoring:  The TWDB will install a sensor in the playa basin to record water levels during inundations.  Project staff will make semi-annual visits to download data and maintain the sensor, plus a one-time topographic survey of the playa basin with GPS equipment.

Advanced Monitoring:   This option includes activities described above, plus installation of a small tripod-mounted meteorological station and subsurface sensors to track infiltration and recharge to the aquifer.  The sensors will be connected to a solar-powered data logger and cellular modem to record and transmit results to the research team on a weekly basis. 

Playa Modification Assessment:  This option includes three years of advanced monitoring, then implementation of playa modifications designed to increase recharge, and finally three more years of monitoring to evaluate any changes in groundwater recharge.  Modifications may include wetland restoration activities such as sediment removal and buffer strip planting; re-vegetation of playa basins with deep-rooted forage plants to loosen heavy soils; or physical modification by deep plowing or V-ditching.  NRCS staff and landowners will be involved in the selection, final design, and implementation of the playa modifications.  All costs of the playa modifications will be covered by the project.
