About Lake Las Vegas and its water

Lake Las Vegas is a 320-acre reservoir in Henderson, built in the channel of the Las Vegas Wash and surrounded by homes and resorts. The lake itself is separate from your household supply. Homes here are within the City of Henderson, and Henderson’s 2024 Water Quality Report says the city’s water comes from the Colorado River, nearly 90% from Lake Mead and about 10% from a deep groundwater aquifer, supplied by the Southern Nevada Water Authority.

The report lists typical hardness at 267 ppm, or 16 grains per gallon, classified as very hard, and suggests a softener setting of 16 to 19 grains per gallon.

Common water problems in Lake Las Vegas homes

  • Glass and stone: spotting on large windows, shower enclosures, and natural stone surfaces.
  • Appliances: scale in water heaters, ice makers, and coffee and espresso machines.
  • Chlorine taste: Henderson disinfects with free chlorine, which many residents prefer to filter out of drinking water.

Water treatment options for Lake Las Vegas

Henderson’s report lists the Southern Nevada Water Authority’s Alfred Merritt Smith and River Mountains facilities as treatment sources. It also notes that the City of Henderson Water Treatment Facility has been out of service since June 2022 because of low lake levels, so the city relies on those regional plants. For your home, the practical takeaway is the same: very hard water and a chlorine residual at the tap. We start with a free in-home test, measure both, and recommend a system sized to your home and how often it is occupied.
