service. she joins us from california. i think what people find the most interesting is this is affecting people as far as the northernest part of the state. could you explain that to us? >> reporter: the rim fire has made substantial impact statewide. we have air quality impacts and we have the fire threatening the watererwater reservoir. we have the impacts of the fire of the county and of the water reservoir that supports san francisco county and they are clean water system. >> are you having to pull in people from other states? ho are you on manpower? >> you know, resources are stretched across the state. we have resources coming not only from neighboring

jurisdictions of fire location but across the state. but what we have on the rim fire, it's a state priority, we have over a thousand firefighters working on that fire around the clock, and resource versus come literally from across the tate to--across the state to assist in that battle. >> where do we stand on evacuations? >> have have been ten communities under evacuation advisory. they are strongly encouraged to seek shelter elsewhere. there is a shelter set up at the fairground there in the county, and we've had people utilizing that facility. there is a concern, yes, because the fire is now well over 125,000 acres and only 25% contained. what makes this fire most treacherous, it's high terrain, rural area, it's timber burning mostly. the threats, the evacuations are
