TUOLUMNE COUNTY (CBS/AP/BCN) – The massive Rim Fire burning in and around Yosemite National Park has reached the area surrounding the Hetch Hetchy Reservoir, which provides water to San Francisco residents, city utility officials said Tuesday.
Meanwhile, firefighters have reported more progress Tuesday in fighting the massive wildfire,
The blaze, which has blackened nearly 180,000 acres, was not expected to affect the quality of the Hetch Hetchy water because of the rocky terrain and limited brush along the reservoir, according to the San Francisco Public Utilities Commission.

Since before the Rim Fire began on Aug. 17, the SFPUC has been transferring water from the full Hetch Hetchy Reservoir to other reservoirs closer to San Francisco, and is now increasing that amount from 275 million gallons to 302 million gallons a day as a precaution.
SFPUC officials say the water’s turbidity, or cloudiness, is well below state-mandated levels despite some ash falling onto the reservoir’s surface.
