WARM SPRINGS, Ore. (AP) — Residents on the Warm Springs Indian Reservation have been advised to boil water before using it because of a break in the water delivery system.

The notice was issued after a mainline break where the water pipes cross Shitike Creek, according to the public utilities branch of the Confederated Tribes of Warm Springs.

The break could allow harmful microbes into the water system, which if consumed could cause diarrhea, cramps, headaches and other symptoms, and could pose a special health risk to infants, the elderly and people with compromised immune systems.

Warm Springs were issued boil water notices multiple times last year due to breaks in the water infrastructure that required emergency repairs in Shitike Creek, The Bulletin reported.

Water crews will make repairs that are expected to be completed by July 3. Recharging the system will require an additional 24 hours.

The areas affected include Kah-Nee-Ta Resort, Wolfe Point, Sunnyside, Dry Creek, the Warm Springs industrial park, Miller Heights, the Campus, Greely Heights, the senior center, Tenino Valley, West Hills, Tenino Apartments and the U.S. Highway 26 corridor, which includes the Indian Head Casino, Eagle Crossing and The Museum at Warm Springs.
