UTILITY HISTORY

Lake Cities MUA: three towns, one water authority

Lake Dallas gets its water from the Lake Cities Municipal Utility Authority, created in 1963 to provide water and wastewater service to Lake Dallas, Shady Shores and Hickory Creek. Its 2025 report lists several old wells that are abandoned or plugged, three wells near the West Lake pump station that still operate, and treated surface water bought from the Upper Trinity Regional Water District. Upper Trinity, created in 1989, is the Denton County wholesaler. The old Lake Dallas reservoir that named the town was Dallas's main water source for 31 years.
