Glenn Cunningham Lake encompasses 390 acres with a maximum depth of 23 feet, operating as a no-wake lake with a 5mph speed limit. The lake features accessible kayak launches, including a specially designed ADA-accessible launch with benches and rail systems to help visitors transition from wheelchairs into kayaks. Kayaks and stand-up paddleboards are available for rent through Neighborhood Offshore.

The lake reopened in 2021 after extensive renovations, including improvements to boat ramps and fishing platforms. A 6.2-mile concrete trail now circles the entire lake, connecting various amenities and access points. There are three main public entrances with parking areas: one off State Street at the marina, another at the overlook, and a third off N 96th Street which provides access to the accessible kayak launch.

The surrounding parkland covers more than 1,050 acres, including 450 acres of designated wildlife area north of State Highway 36. The lake was originally constructed in 1977 by the U.S. Army Corps of Engineers for flood mitigation and recreation purposes.

Recent water quality monitoring has noted occasional harmful algal blooms during summer months, so paddlers should check current conditions before planning trips. The park is open daily from 5:00 AM to 11:00 PM, with no entrance fee required.

Facilities include picnic shelters, restrooms, and a marina. For overnight stays, the park offers camping options including 42 full hook-up sites, 40 electric sites, and 7 tent camping sites. Swimming is not permitted in the lake.

The lake and its surroundings were significantly upgraded in 2014 with the addition of a 36,000-square-foot universally-accessible facility, making it one of Nebraska's most accessible paddling destinations.
