Available information for airport

Sullivan Lake is a unique recreational paradise. There are many forms of recreation available. One can swim, fish, boat, and camp. There are resorts nearby and a Forest Service Campground, with all the amenities, just through the fence. You can camp on the airport, and use the picnic tables along the west edge. At Sullivan Lake, you can really enjoy the out of doors and relax in your own way.

The 1,765 x 150 foot turf strip slopes uphill to the north, and is somewhat rough, although extensive ground squirrel management efforts by the USDA Wildlife Services over the last two years have significantly mitigated the squirrel population and resulting runway damage caused by the burrowing animals. With the help of airport volunteer sponsors, we have made fantastic gains to repair the runway surface by filling in many holes.  There will always be some ground squirrel activity and resulting holes . The estimated 2,614 foot field elevation and the hot summers do cause density altitude problems. Recent airport improvement in 2011 include new airport fencing, new wind cones, and significant tree obstruction removal on the north threshold and along both sides. Terrain rises fairly rapidly to the north and the canyon walls narrow quickly. The approach from the lake is clear, and departures over the lake are relatively simple. Animals love to graze on the runway and nearby campers have been noted to be swimming off the threshold at the lake end.  Overflight is essential to check the airport, move the animals and people, and to locate any burrows which might be in your landing path. Wind indicators are located on the northwest and southeast edges of the runway. Do not land on the extreme west edge as the picnic tables will ruin your whole day. The airport is generally open from June 1 to Oct. 1.
