How this score is calculated

Water temperature19.7 / 20

72°F and falling (-1.6°F / 3 days) against a 60–85°F active band.

Barometric pressure9.0 / 15

30.26 inHg and rising (+0.13 / 24 h).

Wind10.0 / 10

14 mph out of the SW. Ideal chop on wind-blown structure.

Water clarity10.0 / 10

2.9 ft of visibility. Good working clarity for both reaction and finesse baits.

Water level10.0 / 10

-0.9 ft from normal pool and rising (+0.5 ft / 7 days).

Moon & solunar5.2 / 10

56% illumination. Quarter moon — weaker feeding periods, rely on light change.

Seasonal pattern9.9 / 10

Fall pattern is fully established.

Sky & rain12.0 / 15

81% cloud, 70°F air, 0.8 in of rain in 24 h.

WhyWater has dropped 1.6°F in three days, so fish are sliding back to the first deeper break, rising post-front pressure tightens fish to cover and slows the bite, heavy cloud extends the low-light bite well past sunrise, a 14 mph SW wind is stacking bait on the wind-blown banks.

Backup pattern

Squarebill crankbait along hard cover for largemouth bass — Flip cypress trees and stumps in Marion; fish the grass and canal current in summer.

Typical structure profile for Santee Cooper Lakes (Marion & Moultrie): flooded cypress and stumps in marion, the diversion canal, open-water flats and humps in moultrie, hatchery and pinopolis dam areas. Average depth 18 ft, maximum 75 ft.
  • Flooded cypress and stumps in Marion
  • The diversion canal
  • Open-water flats and humps in Moultrie
  • Hatchery and Pinopolis dam areas
  • Grass and lily pads in the upper lake

Substrate

Bottom composition and why it matters

  • Mud 26%

    Warms fastest in late winter and holds wintering bait, but goes dead in the summer heat.

  • Sand 18%

    Clean bottom for bait schools and sight-feeding fish, but little cover — look for the edge where sand meets something else.

  • Vegetation 18%

    Oxygen, shade and ambush cover. The outside grass edge is the highest-percentage line on most lakes.

  • Timber 14%

    Vertical cover fish use to change depth without leaving structure — key on standing timber during frontal swings.

  • Clay 12%

    Holds hard bottom in stained water and dumps the most colour after rain. Crankbait banks.

  • Gravel 6%

    Primary spawning substrate. Fish stack on gravel transitions when water hits the 58–66°F band.

  • Rock 5%

    Holds heat in spring and crayfish year-round — the first place smallmouth and staging bass set up.

  • Brush / artificial 1%

    Man-made brush piles and docks concentrate crappie and bass, especially where they sit on a depth change.

Targets

Target species at this water

Catfish

Trophy blues to 80+ lb. Drift cut herring or gizzard shad over 25–45 ft flats in Moultrie; shallow in Marion in spring.

Color
n/a — scent driven
Retrieve
Static or 0.5–0.8 mph controlled drift
Best time
Sunset to midnight; all day when water is stained

Pushes shallow to spawn in rock and bank holes at 70–78°F, then feeds on channel edges at night through summer and gorges on shad in the fall.

Largemouth Bass

Flip cypress trees and stumps in Marion; fish the grass and canal current in summer.

Active temp
58–82°F
Structure
Submerged grass edges, main-lake points, laydowns and dock lines
Technique
Texas rig / swimbait
Bait
Live shiners
Lure
4.5 in paddle-tail swimbait (3.5"–5")
Color
Green pumpkin / natural shad
Retrieve
Slow to moderate, bottom contact every few feet
Best time
First 3 hours after sunrise and the last 2 before dark

Stages from wintering creek channels to secondary points at 52–58°F, spawns on hard bottom at 62–68°F, then slides to grass edges and ledges once surface water passes 78°F.

Crappie

Enormous numbers. Trolling jigs over 8–14 ft open water in Marion is the local system.

Active temp
50–72°F
Structure
Brush piles, standing timber, bridge pilings and creek-channel bends
Technique
Vertical jigging / live-scope casting
Bait
Minnows under a slip float
Lure
1/16 oz hair or plastic jig (1.5"–2")
Color
Chartreuse / black-blue in stained water
Retrieve
Hold still above the fish, tiny shakes
Best time
Late afternoon and full dark under lights

Moves to shallow wood at 56–62°F to spawn, then relates to 12–20 ft brush all summer, and follows shad into creek arms in fall.

Striped Bass

Landlocked stripers below Pinopolis; seasonal regulations are strict.

Active temp
55–72°F
Structure
Open-water bait schools, river channels, dam tailraces and long points
Technique
Live bait planer boards / vertical jigging
Bait
Live gizzard shad or herring
Lure
1 oz flutter spoon or 5 in swimbait (4"–7")
Color
Chrome / pearl white
Retrieve
Vertical lift-drop or steady mid-column pull
Best time
Dawn and the hour either side of dark

Runs up major tributaries in spring at 55–65°F, suspends over the thermocline through summer, and schools on the surface chasing shad once water falls under 70°F.

Patterns

Season-by-season patterns

Winter

52–58°F

Big blue cats concentrate in deep holes in Moultrie; crappie stack on brush at 14–20 ft.

Spring

62–78°F

Bass spawn in the cypress; crappie flood the shallow wood; catfish move to the flats to feed on spawning shad.

Summer

84–87°F

Fish the diversion canal current and deeper timber; catfish drifting over open flats produces day and night.

Fall

64–80°F

Shad schools scatter and everything feeds; excellent drifting for cats and schooling bass in Moultrie.

About Santee Cooper Lakes (Marion & Moultrie)

Two connected reservoirs: Marion is a shallow, stump-filled cypress swamp with dark water, while Moultrie is deeper and more open. The system is famous for trophy blue catfish and a strong crappie and bass fishery, with the diversion canal connecting the two.

Local knowledge

Expert notes

  • Drift speed for big blues here is 0.5–0.8 mph. Faster than 1 mph and you pull the bait past the fish in this soft-bottom water.
  • Lake Marion's stump fields are unmarked and will end a day fast. Learn one creek arm properly instead of running the lake.
