Cheyenne BOPU

People are also being told to avoid doing laundry or using hot water while the water is discolored.

With sub-zero temperatures, the BOPU is warning people to protect their pipes.

Low temperatures of -20 or colder are expected.

Although the algae have been found in the causeway, the release says it has not been found in the reservoir itself, which supplies drinking water to the city of Cheyenne.

But even with the end of those restrictions, the BOPU is reminding people about the other water conservation rules that remain in effect.

The discolored water is being seen across south Cheyenne.

Washing hard surfaces, such as sidewalks, parking lots or driveways with a hose is prohibited except when needed for safety, health or construction-related reasons.

The caller poses as a BOPU employee to get credit card information from victims.

When asked about a long term threat to the city water supply from the fire, Egenhoff called that a" really hard question...I don't want to mislead anybody because I really don't know how this fire is going to behave.''

Other watering rules remain in effect, including a ban on wasting water by allowing it to run down the street.
