Texas has few natural lakes, so engineers stepped in — the state holds nearly 200 man-made reservoirs scattered across 15 river basins. One of the least crowded sits in central Texas, about an hour east of Waco: Lake Limestone, a 12,500-acre impoundment created when the Sterling C. Robertson Dam was finished in 1978. It was built to supply water, like Possum Kingdom Lake and Lake Granbury, but it has quietly become a low-key escape for fishing, boating and camping.

The water won't win any beauty contests — it's murky rather than sapphire blue — but it's some of the richest fishing in the region. Largemouth bass, white bass, crappie and three kinds of catfish live here, and spring is the prime season. Local tactics: bright topwater lures cast near logs and vegetation for bass on sunny days, worms or live bait fished after dark for catfish. You can cast from the bank or public docks, or launch for free at one of four public boat ramps (two of the easiest to reach sit off Farm to Market Road 3371). Mind submerged trees in the creek arms, and note there are no boat or canoe rentals — bring your own.

Even non-anglers get a show. A pair of bald eagles has lived at the lake for more than two decades, diving for fish overhead, while egrets and great blue herons stalk the shoreline — a handy tip: where the herons feed, the fish usually are. Anglers 18 and over need a Texas fishing license unless an exemption applies.

The lake stays uncrowded partly because flashier lakes sit closer to Houston and other cities, and partly because development is minimal. Three parks around the shore offer free primitive camping: picnic tables, restrooms and a boat ramp, but no water or electric hookups. Expect white-tailed deer wandering past your campfire rather than crowds.

If you'd like more comfort, options exist. Running Branch Campground & Marina on the southwest corner has RV hookups and fishing cabins, while Lake Limestone Campground & Marina on the east shore runs a 46-site RV park plus cabins, a fishing pier, play area and a restaurant serving three meals a day. Tripadvisor reviews are mixed (spotty cell service comes up often), though Google reviews are strongly positive. Limestone Fields also rents modern lakeside cabins for couples or groups. Note that Waco's regional airport (ACT) is the closest air link, with Dallas-Fort Worth and Houston both two to three hours away by car.

Why bother? For anyone tired of booking boat slips months ahead or fighting for shoreline space at better-known Texas lakes, Lake Limestone offers the rare luxury of space. It suits self-sufficient travellers: anglers with their own gear, RVers and tent campers happy with basics, and anyone who counts a heron sighting as a good morning. Pair it with Davy Crockett National Forest to the east, or detour to the Highland Lakes near Austin and the Piney Woods region for more under-the-radar water in the Lone Star State.
