Conditions
Surface temperatures are running 80–88°F across most of the lake, with the Sac River Arm and back ends of creek coves touching the top of that range. The Grand River Arm and main Osage channel are slightly cooler and holding better oxygen at depth. Lake levels are in the normal summer operating pool. Expect afternoon thunderstorms mid-week — check the Corps of Engineers lake level gauge before launching, and watch for floating debris after any significant rain event. Early morning fog is common this time of year; run slow until visibility clears.
Crappie Report
This is the grind week of mid-summer crappie fishing, and that is not a bad thing if you know where to look. Post-spawn fish have settled onto deeper brush piles and main-lake structure in the 18–28 ft range, and they are not moving much until water temperatures begin to cool in September.
The Grand River Arm out of Bucksaw and Long Shoal is producing the most consistent crappie action. Target submerged timber edges and man-made brush in 20–26 ft of water. Use electronics — side imaging or down imaging — to find the specific piece of structure holding fish before you drop a line. Stair-stepping a 1/16 oz jig tipped with a 2-inch paddle tail or a live minnow through the top of the brush column is the most effective presentation. Let the jig fall slowly and watch your line for the subtle pickup.
The Tebo Arm also has good deep timber numbers right now and tends to be less pressured on weekends. The Pomme de Terre Arm flats are worth checking early morning in 15–18 ft near channel edges where crappie stage to feed on shad before retreating deeper as the sun climbs.
Slow down your presentation in the heat. Crappie are lethargic and will short-strike a jig moving too fast.
Bass Report
Largemouth bass are following a reliable summer schedule: active at first light, largely off the bite by 9 a.m. Target main-lake points, riprap banks along the Osage Arm near Warsaw, and any flooded vegetation edges in 3–8 ft during the first hour after sunrise. Walking baits, hollow-body frogs, and noisy chuggers are all worth throwing in low-light conditions.
Once the sun is up, flip heavy cover — dock pilings, laydown timber, and deep brush in 12–18 ft — with a Texas-rigged creature bait. Drop shot rigs along main-lake ledges can pick up suspended bass through midday if you are willing to work for them.
Catfish Report
This is where mid-summer shines at Truman, and night fishing is the headline. Channel catfish are highly active after dark and responding well to cut shad and chicken liver fished on the bottom along main river channels and near dock lights. The area around Sterett Creek and Anglers Port on the Osage Arm is productive for channels most summer nights.
Blue catfish prefer deeper, cooler water. Target the main Osage channel in 20–35 ft near the dam tailrace area using fresh cut bait. Flatheads are in the heavy timber of the Grand and Sac arms — large live bluegill fished on a tight line near logjams after midnight is the classic approach.
Where to Fish This Week
- Grand River Arm (Bucksaw/Long Shoal) — Best bet for deep crappie on timber in 20–26 ft. Launch from Bucksaw Resort for easy access to the best structure.
- Tebo Arm — Quieter than the main arms, solid deep crappie numbers in flooded timber. Good option on busy summer weekends.
- Osage Arm near Warsaw (Sterett Creek / Anglers Port) — Night catfish on the river channel and topwater bass at dawn along the riprap.
Pro Tip
In water this warm, crappie stack tight to the very top of brush piles rather than suspending above them. Drop your jig to the bottom of the brush to find the depth, then work back up and focus your presentations on the top 4–6 feet of the structure. If you are marking fish on the sonar but not getting bites, slow your retrieve to almost nothing — count to five between each lift of the rod tip. That pause is what triggers the bite in July.
