Mobile-Tensaw Delta Fishing Report for September 25 – October 1, 2026

Powered by RedCircle

In this week’s Mobile-Tensaw Delta Fishing Report, host Nick Williams is joined by Peter Jordan for a late-summer look at South Alabama’s blackwater creeks, followed by Matt Frazier with a Big Creek Lake bass and crappie report. Peter explains why cool, shaded blackwater rivers can provide excellent spotted bass fishing even while the surrounding Delta remains hot, and he breaks down productive fly and conventional tackle approaches for fishing current, deep holes, and structure.

Matt reports that Big Creek Lake fish are moving deeper as late-summer heat hangs on. Bass and crappie are both using deeper water and submerged hydrilla, while Carolina rigs, jigs, spinnerbaits, and natural-colored soft plastics are producing for anglers willing to adjust to the lake’s clear water and depth.


Conditions Recap

Late-summer heat is still a major factor around the Mobile-Tensaw Delta, but conditions can be dramatically different depending on where anglers fish. Nick noted surface temperatures around 90 degrees in parts of the lower Delta, while the shaded blackwater creek he fished with Peter was considerably cooler. Groundwater, springs, moving water, sandy bottoms, and heavy tree canopy can combine to create thermal refuge for both fish and anglers.

Those cooler creeks are already setting up well for the transition toward fall. Spotted bass remain aggressive, and Peter says the fish will increasingly key on larger baitfish and streamers as the season progresses. Heavy rain is the biggest condition to watch because a major rainfall can quickly blow out these smaller rivers and temporarily disrupt the bite.

Big Creek Lake is following a very different pattern. Matt says fish that were commonly holding in roughly 10 to 20 feet of water a month ago have been transitioning toward 30 to 40 feet. Bass and crappie are both moving deeper, although schooling bass can still come to the surface and provide fast action. The lake’s clear water and extensive hydrilla remain important pieces of the pattern.


Blackwater Creek Bass Fishing With Peter Jordan

Peter Jordan says South Alabama’s blackwater rivers and creeks offer one of the region’s most enjoyable late-summer fishing opportunities. These systems typically have tea-stained water, sandy bottoms, steady current, and cooler temperatures created by groundwater or spring influence. Heavy tree canopy adds even more shade, creating comfortable habitat for spotted bass and other species when nearby waters are much warmer.

The local spotted bass Peter and Nick target are aggressive, opportunistic feeders. Because many blackwater streams are less nutrient-rich than the Mobile-Tensaw Delta, the fish often cannot afford to pass up an easy meal. Peter says anglers should concentrate on current breaks, laydowns, deeper holes, and other places where bass can sit outside the strongest flow and wait for food to come past them.

Mobility is one of the biggest keys. Peter recommends fishing promising water efficiently instead of spending too much time on one piece of cover. If a fish does not respond fairly quickly, move to the next current break, hole, or laydown. These creeks can be explored by wading or canoe, and many stretches can be reached through public access points and public land.

Fly Fishing Tactics For Blackwater Bass

For fly anglers, Peter recommends roughly a 5-, 6-, or 7-weight fly rod, with a 6-weight serving as a particularly versatile choice. During low-light periods, start with smaller terrestrial patterns or bass bugs in approximately sizes 6, 8, and 10. Rather than immediately working the fly aggressively, Peter likes to begin with a dead drift. He will often make two dead-drift presentations before adding pops or extra action on a third pass.

As the day progresses, streamers become increasingly important. Peter says these fish can show a strong preference for surprisingly large baitfish imitations, with streamers around three inches or larger producing well as the bass feed on river shiners. He prefers a subtle side-to-side action and recommends a weed guard when pushing flies back into cover.

Hellgrammite and crawfish patterns are another important part of the creek system. Peter likes to work these subsurface patterns downstream so they can tumble naturally near the bottom. Crawfish imitations can be especially productive in spring, while hellgrammite patterns become an increasingly important option heading into fall.

Gear and flies mentioned: 5- to 7-weight fly rods, terrestrial flies, bass bugs, Boogle Bugs, Sam’s One Bugs, Stealth Bombers, three-inch-or-larger streamers, hellgrammite patterns, crawfish patterns, and weed-guarded flies.

Conventional Tackle For Creek Bass

Anglers do not need fly tackle to take advantage of the blackwater bite. Peter recommends shorter medium spinning or casting rods that are easy to handle around overhanging limbs and tight creek cover. Small pond-sized spinnerbaits, Mepps-style spinners, compact crankbaits, and crawfish imitations can all produce.

The same rule applies regardless of tackle choice: fish the current and structure, then keep moving. In shallow stretches where much of the bottom is visible, deeper holes are obvious high-percentage targets. Nick described the fishing as intuitive because anglers can often see exactly where the limited deeper habitat is and immediately understand where bass are likely to hold.

Gear mentioned: medium spinning rods, medium casting rods, small spinnerbaits, Mepps-style inline spinners, small crankbaits, crawfish imitations, and small minnow-style soft plastics.

A Good Family Fishing Option

Peter also likes these creeks as a place to introduce children to fishing and exploring outdoors. Clearer water, sandy bottoms, shade, and relatively shallow stretches give kids opportunities to swim, watch minnows, explore leaf mats with dip nets, and fish without needing a boat or complicated electronics.

He does recommend scouting a new stretch before bringing children. Logjams, difficult exits, deeper holes, and other obstacles can change the best plan for a family trip. Peter also encourages catch-and-release in these smaller waters because their lower productivity means heavy harvest can have a much greater impact than it would in a larger, more productive system.


Big Creek Lake Bass And Crappie Report With Matt Frazier

Matt Frazier says Big Creek Lake’s bass have been transitioning deeper over the past several weeks. Fish that were commonly in 10 to 20 feet of water earlier in the summer are now being found in roughly 30 to 40 feet in some areas. That depth makes Big Creek a very different fishery from many of the shallow creeks and backwaters around the Delta.

Carolina rigs and jigs are producing in the deeper water, while spinnerbaits can still catch fish around ledges. Matt says anglers who approach Big Creek exactly like they fish the river system can struggle because the lake’s depth and clarity demand a different approach.

Soft-plastic color selection also changes in the clear water. Matt has caught fish on black-and-gold combinations but generally prefers natural colors such as greens and other shades that blend into the environment. Nick compared that approach to familiar pumpkinseed, watermelon, and baby-bass style colors. With Big Creek remaining exceptionally clear, subtle presentations can help avoid spooking fish.

Gear and baits mentioned: Carolina rigs, jigs, spinnerbaits, black-and-gold soft plastics, and natural-colored plastics in green, pumpkinseed, watermelon, and baby-bass style patterns.

Deep Hydrilla And Schooling Fish

Crappie are also moving deeper, and Matt says Big Creek’s fish tend to make similar seasonal depth changes. He has continued catching crappie consistently, with schools of fish using deeper water and submerged grass.

Hydrilla is a major feature of Big Creek Lake and can grow in water far deeper than many Delta anglers are accustomed to fishing. Matt reported fish relating to grass around 20 feet deep, while other areas have grassy bottom beginning surprisingly close to the launch and shoreline.

Bass are also schooling, and Matt says surface activity can create opportunities for anglers to catch large numbers of fish when a school erupts. He does not spend his day chasing those schools from a kayak, but he will take advantage when they surface nearby.

Kayak Fishing Big Creek Lake

Matt continues to fish Big Creek from a kayak and says the platform has one major advantage in the lake’s clear water: stealth. A kayak lets him approach fish quietly, although covering Big Creek can require serious mileage. On one recent outing he traveled roughly six miles one way.

One of the most useful additions to his kayak setup has been an insulated fish bag. Matt previously pulled a stringer behind the kayak, which created drag and constantly pulled the boat off course. Moving the catch into a fish bag made travel easier and keeps fish cold. Nick uses frozen two-liter bottles instead of loose ice in his own bag, which provides reusable cold storage without requiring an extra stop for ice.

Gear mentioned: pedal-drive kayak, insulated kayak fish bag, frozen two-liter bottles for cooling fish, and kayak storage systems.

Looking Ahead To Fall And Winter

Matt expects Big Creek bass to make a temporary move shallower during fall before returning to deeper winter water. For anglers hoping to target fish in shallower water, spring remains his favorite period, but the fall transition can provide a shorter window when fish move up and feed.

He is especially enthusiastic about cold-weather fishing. Matt says some of his favorite Big Creek fishing comes when temperatures are around 30 degrees and many other anglers stay home. As the season progresses, that combination of cooler water, reduced fishing pressure, and predictable seasonal movement should create another strong window for bass and crappie anglers.


What To Expect This Week

For anglers looking for an alternative to the hot open waters of the Delta, blackwater creeks offer cooler water, shade, moving current, and aggressive spotted bass. Focus on current breaks, deeper holes, laydowns, and other obvious ambush points. Start with smaller topwater flies during low light, then move toward larger streamers, hellgrammite patterns, crawfish imitations, or compact conventional lures as conditions dictate.

At Big Creek Lake, be prepared to fish deeper. Bass and crappie are using deep water, ledges, schools, and submerged hydrilla, with Carolina rigs, jigs, spinnerbaits, and natural-colored plastics among the productive options. Keep an eye out for schooling bass on the surface, and watch for the coming fall transition to temporarily bring more fish into shallower water.
