What campers say
SYNTHESIZED · MODERATE SIGNAL
Weather
01 / 05
Summer heat hits triple digits with afternoon wind that drives sand.
Multiple campers report daytime highs in the 100s and a reliable afternoon wind off the lake that pushes grit through open sites. April to May and late September come up repeatedly as the windows when temperatures and crowds both ease off.
Water
02 / 05
Lake levels swing hard and the shoreline can sit a long walk from camp.
Recent visitors describe drawdowns that leave former swim spots dry and a hike of roughly a mile to reach water in low years. When the lake is up, swimming and wading work fine, and the north side is reported to have less algae than the south.
Sites
03 / 05
Sites near Highway 155 catch road noise; the back loop trades quiet for rougher roads.
Campers place sites 1 through 73 closest to the highway and note audible traffic, while the loop past site 75 is quieter but has been called poorly maintained with potholes and faded numbering. Shade is uneven, with the area around site 17 singled out as one of the shadier pockets.
Facilities
04 / 05
Vault toilets are the current standard and showers are not reliably available.
Reviewers from the last few seasons report the old shower house is closed or out of service and the dump station has been down on some visits. Most water spigots lack hose threads, and the one threaded tap sits near the dump station.
Wildlife & sky
05 / 05
Mosquitos can be heavy near the water and ants show up in the group loops.
Several campers describe mosquito pressure bad enough to make bathroom trips unpleasant, especially when the lake is high and grass is green. Group sites have also drawn complaints about fire ants and ground squirrel holes underfoot.
