Seasonal Recreation on Lake Catherine

Spring: March Through May

Spring on Lake Catherine opens with the refill. By March 15, Entergy has the lake back to summer pool after the winter drawdown. The state park marina begins limited-hours operation around March 16. Fishing comes alive immediately — crappie are the first reliable bite as water temperatures rise through the 50s into the 60s in March and April. They stack on brush piles in 12–15 feet, responding well to jigs and minnows.

Bass spawning begins in the shallows in April. The shallow main lake coves and the protected arms see largemouth on beds from mid-April through early May. Spring is the best window for topwater bass fishing on Catherine: poppers and walking baits at dawn produce surface action before the sun rises too high.

The state park's Falls Branch Trail to the waterfall is particularly good in spring, when Falls Creek is running well and wildflowers are out along the path. Horseback riding does not start until Memorial Day weekend, but hiking, kayaking, and paddleboarding from the park are available from mid-March forward.

Diamondhead's outdoor amenities come online in spring: the community pool opens, the golf course sees regular play, and the 19th Hole social scene picks up as residents return after winter absence or come out more regularly.

Summer: June Through September

Summer is Lake Catherine at peak operation. The state park marina runs daily 8 a.m.–5 p.m. from Memorial Day weekend through Labor Day. Boat rentals, fuel, bait, and swimming beach are all available. The marina's ethanol-free fuel option is appreciated by boat owners with carbureted engines and older motors.

On-water recreation in summer means boating, tubing, skiing, kayaking, and paddleboarding with noticeably less traffic than Lake Hamilton. This is the season where Catherine's character advantage is most obvious: a 4-hour Saturday afternoon on the water in July involves open stretches of lake, minimal wake-boat chop in the coves, and the ability to anchor in a quiet arm without a crowd.

Fishing in summer requires schedule management. Largemouth bass bite early (before 8 a.m.) and late (after 6 p.m.) on topwater and shallow presentations. Midday bass move deep onto main channel structure. Crappie are in 15–20 feet on brush piles during the heat of the day and can be caught consistently with jigs and minnows. Night fishing for catfish produces well from July through September.

State park programs are in full swing: guided hikes, lake cruises, nature talks, and the nature cabin interpretive exhibit are all open and staffed. Horseback riding runs daily through Labor Day. Summer evenings at the state park swimming area are popular with both residents and day visitors from Hot Springs.

Entergy's weekend whitewater releases from Remmel Dam provide recreational flows for paddlers in the Ouachita River below the dam each Saturday and Sunday afternoon from Memorial Day through Labor Day. This is separate from on-lake recreation but available for residents interested in river paddling close to home.

Fall: October Through Early November

Many full-time residents consider fall the best season on Lake Catherine. October brings cooler water temperatures, fewer day visitors, and improved fishing across the board. The Ouachita Mountain foliage along the lake's valley walls turns in October — the fall color drive on Highway 171 is legitimate and worth making time for.

Crappie move back to shallower brush piles as the water cools through the 60s. Fall crappie fishing on Lake Catherine is consistently productive — limits are achievable on brush in 10–15 feet with jigs and live bait. The fall 2024 AGFC report specifically cited Lake Catherine crappie as “great” in the fall pattern.

Bass return to shallower structure and begin responding to crankbaits and swimbaits as fall transitions into pre-winter. October topwater fishing for bass on Catherine is underrated — fewer anglers, more active fish, excellent conditions.

In late October, AGFC begins its fall trout stocking in the Catherine tailwater below Carpenter Dam. The November influx of rainbow trout creates a tailwater fishery that runs through winter. Water temperature below the dam drops into the 40s and colder, providing the cold water trout require. A trout permit is required to keep fish.

The drawdown begins approximately November 1. The fall recreation window on the lake itself closes as the water drops and the marina shifts to reduced hours. Boat owners begin seasonal dock management as the 3-foot drawdown proceeds.

Winter: November Through February

Winter on Lake Catherine is the quietest season. The state park marina closes around November 1 and stays closed until mid-March. The lake sits at drawdown level. Day visitors are minimal. The Diamondhead community contracts to its year-round population.

What winter offers: the tailwater trout fishery below Carpenter Dam. Shane Goodner of Catch'em All Guide Service provides guide services targeting trout and striper in the cold-water releases below the dam. Generation flow schedules from Entergy directly affect fishing conditions — high generation creates fast, often muddy water; lower flows produce clearer conditions for trout.

Crappie fishing on the lake itself continues through winter with slower techniques. Deep brush piles in 20+ feet produce fish when you slow down sufficiently. Bass are catchable in winter on slow-rolled jigs along deep shoreline rock. Winter bass fishing on Catherine is not high-volume, but it is peaceful and produces quality fish for patient anglers.

Hiking at the state park is available year-round. Winter hiking in the Ouachita Mountains has a stark, clear quality that summer hiking doesn't: no leaves on the hardwoods opens the ridgeline views, the creek levels are up from fall rain, and the trails are typically uncrowded. The Slunger Creek paved trail remains accessible regardless of season.

Year-Round: Kayaking and Paddleboarding from the State Park

Kayak and stand-up paddleboard rentals at the state park marina are available year-round, even when motorized boat rentals are not. This makes non-motorized water recreation accessible in all four seasons. Winter kayaking on a calm Catherine morning, with the mountain valley walls reflected in still water and no other boats around, is a genuinely distinctive experience that residents cite as one of the lake's underappreciated qualities.
