In Colorado’s northeastern plains near Sterling, Jumbo Reservoir (also known as Jumbo Lake) offers a 1,200-acre canvas for camping, fishing, and boating. Following a severe drought in 2006, the lake was restocked and has since rebounded as a go-to for year-round angling. Fishermen come for rainbow trout, largemouth bass, wiper, and crappie. Campgrounds with basic amenities line the lake’s southern shore, while the wide-open sky makes it a hotspot for stargazing and birding. The low elevation and grassy surroundings give it a laid-back prairie lake feel, perfect for weekend getaways far from the mountain crowds.
