Rend Lake stays in its summer rhythm: early magic, midday siesta, evening reprieve. The river is running 37 cfs, dropping and clearing. Today brings clear skies, wind WSW around 6 mph, steady pressure near 1013 hPa and a high of 100. Water sits around 84 F for the season (estimated). With the last quarter, the solunar majors run 5:39 AM-7:39 AM and 5:39 PM-7:39 PM: plan around them and beat the heat.

The plan, species by species

Hybrid striped bassGood

Schooling at first light over main-lake humps and channel edges. Slabs, tail spinners and live shad once you mark bait. It is usually over by mid-morning.

Catfish (blue, channel)Good

Anchor on 20-30 ft baited holes with punch bait or cut shad. They keep biting through the heat when everything else quits.

Largemouth bassFair

Topwater at first light on points and seawalls, then slide out to 12-25 ft brush and points with a Carolina rig, deep crank or drop shot. The bite is dawn, dusk or deep.

CrappieSlow

Straight down on bridge pilings and deep brush at 15-25 ft. Minnows outfish jigs in hot water; move until the graph shows them stacked.

Tomorrow: Similar at 102 F. The solunar majors shift about 50 minutes later.Next report: Sat, Sep 5, 6:30 AMHow this report is made →

Largemouth bass illustration

Largemouth bass

Best: spring and fall

The headline act on most American reservoirs. Relates to cover: docks, brush, grass edges and points. Topwater at first light on points and seawalls, then slide out to 12-25 ft brush and points with a Carolina rig, deep crank or drop shot. The bite is dawn, dusk or deep.

Hybrid striped bass illustration

Hybrid striped bass

Best: Jun-Sep

Stocked white bass x striper cross. Open-water shad chasers; birds and busting bait give them away. Schooling at first light over main-lake humps and channel edges. Slabs, tail spinners and live shad once you mark bait. It is usually over by mid-morning.

Catfish (blue, channel) illustration

Catfish (blue, channel)

Good year-round

The most reliable bite on most southern waters. Blues run big; channels fill the cooler. Anchor on 20-30 ft baited holes with punch bait or cut shad. They keep biting through the heat when everything else quits.

Crappie illustration

Crappie

Best: Nov-Mar

Brush piles, bridge pilings and standing timber. The fish fry favorite. Straight down on bridge pilings and deep brush at 15-25 ft. Minnows outfish jigs in hot water; move until the graph shows them stacked.

About this water

18,900 acres on the Big Muddy, Franklin/Jefferson counties, IL. Corps, impounded 1971.

Fishing Rend Lake: the full guide

The downstate standby

Rend spreads 18,900 shallow, fertile acres across Franklin County: Illinois' most productive crappie factory (the spring flats fill with boats and limits), reliable hybrids over the old river channel, and largemouth in the buckbrush when water rises. Flat, windy and generous: the definition of a meat-and-memories lake.

Flats crappie mathematics

Rend's crappie live by depth inches: spring waves flood the buckbrush at 2-4 ft, summer schools hold the 10-14 ft flats' scattered cover, winter compresses to the deepest channel bends. The lake's shallowness makes weather king: fronts move fish in hours: our panels tell the tale.

Beyond the slabs

Rend's white bass and hybrid schooling (the dam basin and Route 154 flats) rivals the crappie fame locals-only; channels cats fill juglines lake-wide; and the largemouth program around Gun and Atchison creeks' wood discreetly produces 20-lb bags each spring.

Common questions

When do Rend crappie go shallow?

Water at 58-64F: typically mid-April: fills the buckbrush lake-wide. It is southern Illinois' rite of spring: minnow sales triple and sick days spike.

The 154 corridor

Rend's Route 154 corridor concentrates its life: the causeway riprap holds spring crappie and fall bass, the adjacent flats stage the white-bass schools, and the visitor-center bank access serves shore families with bluegill and cats. When wind rules the open water, this mid-lake spine keeps producing: the most fishing per parking spot in southern Illinois.

Does Rend Lake hold big bass?

Quiet ones: the stumpy bays produce 6-8-lb fish each spring for the few targeting them among the crappie fleet. Black-blue jigs in the Gun Creek wood: low pressure, reliable quality.
