Saint Andrew Sound Depth Map & Fishing Spots (GA)

Seasonal forage outlook

Atlantic menhaden estuary movementActive window

Typical here: Apr 1 – Nov 30 · a conservative warm-season search window for estuarine juveniles and coastal schools; local recruitment, salinity and temperature can shift or erase a school at any one inlet

juvenilemoving-water periods around creek mouths, channel shoulders and protected estuary edges — match the small young-of-year bait rather than defaulting to an adult bunker profile
adultdawn, dusk and tide changes make surface schools and bird activity easiest to see — fish the outside or down-current edge of a confirmed school instead of repeatedly casting through its center

A visible school is stronger evidence than the date. Menhaden can compress bluefish, drum and other predators onto an inlet seam or the down-current side of a point.

Swim a paddletail, bucktail or small topwater around the school edge and first nearby depth break, matching the profile actually present.

The event happens over inlet approaches, estuary channels, tributary mouths, windward points and current seams holding visible schooling bait

Striped mullet fall movementActive window

Typical here: Aug 15 – Nov 30 · a broad late-summer and fall search window around inlet-connected routes; the North Carolina fishery is concentrated in September and October, but weather and water temperature move the local pulse

adultlow light and moving water are practical times to check inlet approaches, banks and channel-connected points — confirm a school visually and size the presentation to the fish actually moving

Migrating mullet can organize predators along inlet approaches and channel-connected points, but the window does not guarantee a run at a particular tide.

Work a mullet-size topwater, paddletail or suspending plug beside visible schools and across the first measured break on their route.

The event happens over inlet approaches, channel-connected points, creek mouths and current seams along estuary-to-ocean routes

Recommendations come from depth structure and seasonal species behavior. Treat them as a starting point, not a guarantee. Contours here are interpolated from real agency depth surveys (state DNR / USACE). Never use for navigation. Always check local regulations.

Fishing Saint Andrew Sound: what the data says

6,796-acre sound near Jekyll Island. The water tops out around 43 ft. The depth chart is built from real agency bathymetric surveys, so measured depths remain distinct from source interpolation. The channels, holes and drop-offs come from the source data, not a distance-from-shore model. Every species below gets its seasonal read from the same numbers driving the chart.

The outline encloses 6,784 acres, worked by 15.3 miles of shoreline. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. The shallow band under 15 ft claims about 74% of the surface — that's where the groceries are. Tip to tip the water measures near 4.6 mi with a 4.2-mi widest point. Its nearest charted neighbour, Brunswick River, is 9 mi to the north.

Red Drum (Redfish) fishing at Saint Andrew Sound

Spring red drum (redfish) on Saint Andrew Sound hold shallow, usually 1 to 8 ft. They move out to 2 to 12 ft in summer and finish the year down in 3 to 15 ft. Put Cumberland River inflow first on the milk run — an inflow / creek mouth near 20 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a weedless gold spoon or a paddletail swimbait.

Season	Depth	Best window	Start at	Go-to baits
Spring	1 to 8 ft	dawn & dusk	Shallow bay flat (5 ft)	Gold weedless spoon, Paddletail on 1/4 oz jighead
Summer	2 to 12 ft	dawn & dusk	Shallow bay flat (5 ft)	Weedless gold spoon, Paddletail swimbait
Fall	3 to 20 ft	dawn & midday	Cumberland River inflow (20 ft)	1/2 oz spoon (schools), Big paddletail
Winter	3 to 15 ft	midday & dawn	Old creek channel (3 ft)	Scented soft plastic on 1/8 oz head, Slow-rolled paddletail

Spotted Seatrout fishing at Saint Andrew Sound

Spring puts spotted seatrout in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 4 to 15 ft, wintering in 5 to 20 ft. Spring spotted seatrout concentrate at Shallow bay flat, a prime-rated weed flat around 5 ft. Warm-month bites cluster around early morning. A popping cork + shrimp or a 1/4 oz jighead + paddletail (deep grass edge) covers the summer program.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 10 ft	dawn & dusk	Shallow bay flat (5 ft)	Topwater walker, Suspending twitchbait
Summer	4 to 15 ft	dawn	Shallow bay flat (5 ft)	Popping cork + shrimp, 1/4 oz jighead + paddletail (deep grass edge)
Fall	3 to 12 ft	dawn	Shallow bay flat (5 ft)	Popping cork rig, Soft plastic jerkbait
Winter	5 to 20 ft	midday & dusk	Break off the point (17 ft)	Suspending twitchbait (long pauses), Scented plastic crawled on bottom

Southern Flounder fishing at Saint Andrew Sound

Early season southern flounder use the shallows, holding in 2 to 15 ft. Expect a summer slide to 3 to 18 ft, then a winter hold in 15 to 40 ft. Put Old creek channel first on the milk run — a creek channel near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a jighead + gulp swimming mullet or a bucktail tipped with shrimp and you're in the game.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 15 ft	dawn	Old creek channel (3 ft)	1/4 oz jighead + paddletail (white/chartreuse), Bucktail + Gulp shrimp
Summer	3 to 18 ft	dawn	Old creek channel (3 ft)	Jighead + Gulp swimming mullet, Bucktail tipped with shrimp
Fall	5 to 25 ft	midday	Cumberland River inflow (20 ft)	3/8 oz bucktail + Gulp (passes), Big paddletail on the jetty edge
Winter	15 to 40 ft	midday	Deep basin (42 ft)	Slow jig + scented grub in the holes

Sheepshead fishing at Saint Andrew Sound

Early season sheepshead use the shallows, holding in 5 to 25 ft. Even in summer they hold at 3 to 15 ft; winter keeps them in 10 to 30 ft. The chart's best answer is Break off the point — drop-off, 17 ft, good for spring. Best bite is early morning. Tie on a small jig + crab piece and you're in the game.

Season	Depth	Best window	Start at	Go-to baits
Spring	5 to 25 ft	midday & dawn	Break off the point (17 ft)	1/4 oz jighead + fiddler, Sheepshead jig + shrimp piece
Summer	3 to 15 ft	dawn	Main-lake point (6 ft)	Small jig + crab piece
Fall	5 to 20 ft	midday	Main-lake point (6 ft)	Jighead + shrimp, Small crab jig
Winter	10 to 30 ft	midday	open water	Heavier jig + crab (deep pilings)
