A controller schedule that was reasonable last season may not fit today's weather, landscape needs, or local restrictions. Confirm current rules before running an automatic program.
Start with the right authority
Properties may rely on a groundwater district, city, water supplier, or another source. The applicable rule can depend on the water source and location. Contact the authority responsible for your property rather than relying on a generic online schedule.
Somervell County reference
Prairielands Groundwater Conservation District covers Somervell, Johnson, Ellis, and Hill counties. For a Somervell County property, use the district for groundwater information and check your actual water supplier for current watering notices. Somervell County Water District and the City of Glen Rose are useful starting points for their customers; a county or ZIP reference alone does not identify the rules for every property.
Use the system only when it is needed
A working irrigation system is still a tool, not a reason to water automatically. Check rainfall, soil and plant conditions, controller settings, and any active restriction. Do not rely on a fixed schedule in place of current local guidance.
Ask about sensors and system condition
Rain shutoff sensors and controller settings can help prevent unnecessary cycles, but a sensor must be installed, maintained, and tested. A system inspection can also reveal heads spraying sidewalks or zones running longer than intended.
