Wichita Falls Water Hardness & Quality Report (2026)

Wichita Falls, Texas — a major city at the Texas–Oklahoma border — draws its municipal water supply through the City of Wichita Falls Utilities, sourcing from Lake Wichita and Lake Arrowhead — both impoundments on the Wichita River system in Wichita and Clay Counties — supplemented by Lake Kemp and Lake Diversion on the Wichita River in Baylor County, managed by the Wichita County Water Improvement District. The Wichita River drains the Texas Rolling Plains of the Red River watershed. Water hardness reaches 408 mg/L — classified as extremely hard, among the highest in Texas outside the Permian Basin.

Wichita Falls' extreme hardness reflects the Permian evaporite and red bed geology of the Rolling Plains watershed — the same geological formation that drives extreme hardness in Abilene and West Texas. The Wichita River and its tributaries drain the Permian Whitehorse Group (red sandstone, gypsum, and halite), the Permian Blaine Formation (gypsum and dolomite), and the Permian Cloud Chief Formation (dolomite and gypsum) of the Texas and Oklahoma Panhandle region. These Permian evaporite sequences — deposited in the ancient Anadarko Basin and Permian red bed province — contain vast gypsum and dolomite beds that dissolve readily into surface and groundwater, contributing extraordinary dissolved calcium sulfate and bicarbonate concentrations.

At 408 mg/L, Wichita Falls residents face severe scale challenges throughout the home. Calcium and sulfate deposits form within days on shower glass, tile, chrome, and appliance interiors. Water heaters require regular professional maintenance, and dishwashers struggle without dedicated cleaning products. A whole-house water softener is essential equipment for virtually every Wichita Falls household to maintain functional plumbing and normal appliance lifespans.
