Smoke from the Rim Fire, which is now more than 230,000 acres, forced the cancellation of high school soccer and tennis matches from South Lake Tahoe to Reno on Tuesday.

South Tahoe’s non-league tennis matches against McQueen, girls at home and boys away, were both canceled with no make-up date scheduled.

State athletic officials canceled all outdoor events and practices Tuesday in Reno-Sparks, Carson City and surrounding areas when the air quality index exceeded the 100 level shortly after noon.

The 118 reading considered unhealthy for sensitive populations slipped back to a moderate reading of 97 after 2 p.m. It had shown significant improvement at times over the holiday weekend.

Games scheduled for Wednesday and Thursday will be dependent upon an improved air quality, according to Donnie Nelson, Assistant Director of the Nevada Interscholastic Activities Association.

The surrounding counties that fell under this restricted, no-play zone on Tuesday were Mono (Coleville exempt) El Dorado (South Tahoe), Sierra (North Tahoe), Nevada (Truckee), Douglas, Carson, Washoe, Storey and Lyon.

Games and practices have been affected along most of the Sierra’s eastern front since smoke from the fire at Yosemite National Park more than 100 miles away began to thicken on Aug. 22. The fire is now 75 percent contained and is estimate to be in full containment by Sept. 20.
