Drought Restrictions and Watering Rules

Drought Restrictions for Retail Water Customers located in Cordillera Ranch, Johnson Ranch, and Comal Trace

The Guadalupe-Blanco River Authority (GBRA) has Drought Contingency Plans in place to safeguard the water supply for the communities that it serves. Each plan includes five stages of water use restrictions, which may be implemented depending on the severity of drought conditions. Triggers for each stage are based on factors including the water level in Canyon Reservoir and the storage capacity of the water storage facility for each community.

Homeowners can expect to receive notification of any changes to the current stage on this website and via text message and email notification, based on the preferences selected in your customer account.

25 Water Conservation Tips
Puntos de Conservacion de Agua

Check your sprinkler system frequently and adjust sprinklers so only your lawn is watered and not the house, sidewalk, or street.
Run your washing machine and dishwasher only when they are full and you could save 1,000 gallons a month.
Use a broom instead of a hose to clean your driveway or sidewalk and save 80 gallons of water every time.
When you shop for a new appliance, consider one offering cycle and load size adjustments. They are more water and energy-efficient than older appliances.
Adjust your lawn mower to a higher setting. Longer grass shades root systems and holds soil moisture better than a closely clipped lawn.
Put food coloring in your toilet tank. If it seeps into the toilet bowl, you have a leak. It’s easy to fix, and you can save more than 600 gallons a month.
Install a rain shut-off device on your automatic sprinklers to eliminate unnecessary watering.
Reduce the amount of grass in your yard by planting shrubs, and ground cover with rock and granite mulching.
Water your plants deeply but less frequently to create healthier and stronger landscapes.
Avoid installing ornamental water features and fountains that spray water in the air. Trickling or cascading fountains lose less water to evaporation.
Buy a rain gauge to track how much rain or irrigation your yard receives. Check with your local water agency to see how much rain is needed to skip an irrigation cycle.
Encourage your school system and local government to help develop and promote a water conservation ethic among children and adults.
Set a kitchen timer when watering your lawn or garden with a hose.
When the kids want to cool off, use the sprinkler in an area where your lawn needs it the most.
Landscape with Xeriscape trees, plants and groundcovers. Call your local conservation office for more information about these water thrifty plants.
Use a hose nozzle and turn off the water while you wash your car and save more than 100 gallons.
Bermuda grasses are dormant (brown) in the winter and will only require water once every three to four weeks or less if it rains.
Use sprinklers that throw big drops of water close to the ground. Smaller drops of water and mist often evaporate before they hit the ground.
More plants die from over-watering than from under-watering. Be sure only to water plants when necessary.
Bathe your pets outdoors in an area in need of water.
Aerate your lawn. Punch holes in your lawn about six inches apart so water will reach the roots rather than run off the surface.
To save water and time, consider washing your face or brushing your teeth while in the shower.
For hanging baskets, planters and pots, place ice cubes under the moss or dirt to give your plants a cool drink of water and help eliminate water overflow.
Don’t water your lawn on windy days. After all, sidewalks and driveways don’t need water.
Wash clothes only when you have a full load and save up to 600 gallons each month.

Utilice una escoba en vez de una manga para limpiar su camino de entrada o la acera y salvar 80 galones de agua cada vez.
Cuándo usted hace de compras para un nuevo aparato, considera un ciclo de ofrenda y ajustes de tamaño de carga. Ellos son más agua y aparatos energía-eficiente que más viejos.
Ajuste su cortacéspedes a una colocación más alta. Las sombras más largas del césped arraigan sistemas y tienen tierra la humedad mejor que un césped de cerca sujetado.
Ponga alimento el colorido en su tanque de lavabo. Si se rezuma en el tazón de lavabo, usted tiene un escape. Es fácil de fijar, y usted puede salvar más de 600 galones un mes.

Reduzca la cantidad de césped en su yarda plantando los arbustos, y molió la cubierta con piedra y granito que cubren con pajote.

Alente su sistema escolar y la administración municipal para ayudar a desarrollar y promover una ética de la conservación de agua entre niños y adultos.
