The story behind the lake

A young lake with deep roots.

By the mid-20th century, a growing Litchfield needed a dependable water supply, and city leaders looked to the West Fork of Shoal Creek. Construction of the dam began in 1964, and by May 1966 the new reservoir had completely filled — flooding the creek valley to create a lake of more than 1,300 acres with roughly 25 miles of winding shoreline.

The lake was named for Lou Yaeger, the Litchfield leader whose years of work carried the project from ambition to reality. Six decades later it still does the quiet job it was built for — supplying the city’s water and providing flood control — while the recreation that grew up around it has become its public face. More than 140 families call the lake home on weekends or year-round, bald eagles nest along its shores, and summer evenings bring everything from sailboat silhouettes to the city’s Fourth of July fireworks reflected on the water.

On the water & in the woods

Everything to do at the lake.

🚤

Boating, no compromises

One of the few lakes in the region with no horsepower limit — ski boats, pontoons and personal watercraft share the water with kayaks and paddleboards. Ramps on the southwest shore put you out fast.

A City of Litchfield boat sticker is required, available at Marina 1.
🎣

Fishing

A fertile, productive fishery — bluegill, white crappie and channel catfish, with largemouth bass as the marquee species. The Illinois DNR stocks roughly 20,000 bass fingerlings a year. About 10 ft average depth, ~31 ft max.

Nearly 25 miles of shoreline, coves and submerged creek channels.

Milnot Beach

A genuine sandy swim beach with floating inflatables, diving boards and a climbing wall — plus a beach house with restrooms, showers and concessions, and kayak, paddleboard and Corcl rentals.

Trails

The Route 66 Hike & Bike Trail runs about 6.6 miles round trip through the woods along the lake. The 266-acre Shoal Creek Conservation Area protects prime oak-hickory woodland — ~700 plant, 70 butterfly and 70+ bird species documented.

Plus a dedicated equestrian trail network.

Eagles & the quiet season

Bald eagles have nested here since 2005 and are a winter highlight along the tree line. Fall paints the woods copper and gold; spring brings crappie and wildflowers. If you like your lake without company, November through March is your season.

Park grounds open 6 a.m.–10 p.m.
