No potable water, no flush toilets, and no hookups on the site list, confirm what central facilities your group actually gets before booking. Noise from neighboring campers and spotty quiet-hour enforcement frustrate light sleepers, and summer mosquitoes can be relentless.

The reservoir has approximately 35,200 water surface acres, 9,360 land acres and 76 miles of shoreline, and offers excellent fishing opportunity for rainbow trout, perch, ling, and walleye. There are three marina concessions (Goose Bay Marina, Kim's Marina and Yacht Basin Marina) on the reservoir which provide a variety of public recreation facilities and services such as boat launching, camping, rental docks, small stores, etc. Reclamation also provides campgrounds, day use and picnic areas, concrete boat launches, and a seasonal visitor center. A wildlife management area at the end of the reservoir is managed by the Montana Department of Fish, Wildlife and Parks and is home to a colony of terns and pelicans. The upland areas around the reservoir provide habitat for Chestnut-collared Longspurs and Long-billed Curlews, as well as hundreds of Pronghorn antelope, mule deer and white tail deer. <A HREF="http://www.usbr.gov/gp-bin/arcweb_cfr.pl">Current Reservoir Levels</a>

Summer delivers the best experience, with daytime highs in the mid-70s to mid-80s °F and warm lake water for swimming and boating. Expect mosquitoes and crowds. Pack strong repellent and reserve well ahead for weekends. Spring and fall bring quiet and fewer bugs, but wind off the lake can make mornings and evenings chilly, so bring layers. The park stays open year-round for groups willing to trade comfort for solitude.
Best season: warm lake water, swimming and boating; expect crowds and mosquitoes.
