How to fish O.H. Ivie Reservoir with the lake well below conservation pool: channel ledges, the 10" PowerWorm, winter A-rigs and mandatory decontamination.
O.H. Ivie is 19,149 acres of West Texas reservoir with a lake record of 14.52 pounds and a genuine annual crop of 8 to 14 pound largemouth. That is the reason people drive hours to get here. But before you plan a single cast, understand the second most important fact about Ivie: the lake is running well under conservation pool. The most recent Texas Water Development Board reading put it at 43.9 percent full, with the surface at 1530.61 feet against a conservation pool of 1551.5 feet. That is 20.9 feet of missing water, and the trend is falling, down 7.7 points from 51.6 percent a year ago.
Take that seriously when you look at any map or old report. Shoreline cover that is prime at full pool is dry dirt right now. The good news for a trophy hunter is that Ivie's signature pattern was never a shoreline pattern to begin with.
Ivie is built on the Colorado and Concho rivers, and those two channels are the skeleton of the lake. When the reservoir drops this far, the fish do not disappear, they simply stop having options. Flats that held bass at full pool are above the waterline, so the population compresses onto channel swings, main lake structure and the deeper end of the lake near the dam, where max depth reaches 94 feet.
That is a gift in disguise for an angler without a boatload of electronics. There are fewer places for a big fish to be. Idle the Colorado River arm and find the channel bends where the drop is sharpest, then work the 10 to 25 foot band along the edge. The Concho and Colorado confluence does the same job on the other side of the lake and is a known big-fish staging area.
Read the level as a pattern, not a fixed number. Every foot the lake comes back up, push further back into the arms and check the newly flooded terrestrial brush and saltcedar, because bass will follow rising water into cover that has been dry for a long time rather than sit on the old channel. When it is falling, do the opposite: back off to the channel edge and go deeper. Whatever the gauge says the day you launch, that reasoning holds.
If Ivie has one universal technique, it is a 10" Berkley PowerWorm in Junebug on a Texas rig, dragged slowly along the Colorado and Concho channel ledges. It works in every season on this lake, which is unusual for any bait anywhere.
Adjust the weight to the season and depth rather than switching baits:
Why a bait that big on a lake this stained? Clarity here runs anywhere from 1 to 6 feet and a red clay stain shows up after rain, so a fat 10-inch profile crawling along the bottom gives a big fish something to find by feel and shadow. Zebra mussels have cleaned the water up compared to what it used to be, which makes the deep drag more viable than it once was, but the bulk of the worm is still the point.
From December through February, the A-rig is the king bait at Ivie. Massive shad schools set up around the Concho and Colorado confluence and the bass sit with them in 15 to 25 feet. Run a 5-wire with 3.5" white swimbaits and cover water until you find the bait, then slow down and fish through it.
Surface temps in the 45 to 55 degree range keep everything grouped tight, which is exactly what you want when the lake is low and the fish are already concentrated. If the A-rig is not getting bit, the PowerWorm drag on those same deep ledges is the fallback, and a drop shot or shakyhead with a straight-tail worm on deep cliff faces in 25 to 40 feet will pick off fish that will not chase.
Ivie is one of the lakes where an 8" Huddleston Deluxe in Rainbow Trout is a serious tool rather than a novelty. Pre-spawn and post-spawn are the windows. Slow roll it over deep channel structure in 10 to 20 feet and accept that you may go a long time between bites. This is a targeting decision, not a numbers decision: you are fishing for a 10 pound-plus bass and giving up on catching five keepers.
If you want a middle ground, a 7" swimbait on a slow roll in 6 to 12 feet during post-spawn gets more bites while still filtering for size.
The saltcedar invasion along the north shoreline flats has historically given Ivie its spawn cover, and the standard March and April approach is to flip those root mats with 65 lb braid and a 1 oz Texas-rigged PowerWorm in 2 to 5 feet. It is heavy, close-quarters fishing and it produces.
With the lake this far down, verify before you commit a morning to it. A lot of what was flippable saltcedar at conservation pool is standing on dry ground now. Work the current waterline instead and find whatever cover the fish actually have: the lowest band of standing saltcedar, rock, and any brush the falling water has left in 2 to 6 feet. A 5" Green Pumpkin Senko dead-sticked in spawning pockets covers the sight-fishing situations in the clearer sections, and a Watermelon Seed Brush Hog flipped into rocky pockets handles the rest. Spawn temps run 62 to 70 degrees.
From May through September the surface can sit between 85 and 95 degrees and the bass live deep, generally 25 to 40 feet. The main dam area is the anchor: deep structure, a 1 oz football jig in green pumpkin or brown on channel structure, and a 1 oz chrome Hopkins jigging spoon dropped vertically on schooled fish in 25 to 35 feet.
A drop shot with a 4" Roboworm along cliff walls in 20 to 35 feet is the finesse answer when the jig bite is slow, and a 3/4 oz Carolina rig with a 6" Trick Worm works deep main-lake humps in 18 to 30 feet. On a full moon, night fishing is a legitimate option and gets you off the water during the worst of the heat.
Fall is excellent at Ivie. Water backs off into the 65 to 80 degree range, fish leave their deep summer haunts, and the whole lake gets easier to read. Primary depth is 8 to 20 feet.
Keep the PowerWorm on channel ledges in 10 to 18 feet as your baseline. When you see shad get pushed in the Concho arm, pick up the Alabama rig, it stays dominant through fall. A 3/4 oz chrome and blue Rat-L-Trap ripped over 8 to 14 foot transitions handles open-water schooling activity, and a DD-22 in Sexy Shad long-lined across main lake points in 15 to 22 feet will find fish that are still hanging deeper. Trophy-class bass are active in fall, so do not treat it as a numbers-only season.
Zebra mussels are present in O.H. Ivie. Full watercraft inspection and decontamination is mandatory before you leave the lake. Do not skip it, do not hurry it, and do not tow a wet boat to the next lake. Beyond the legal side, the mussels are the reason clarity has improved here, and they will do the same and worse to whatever water you visit next.
Otherwise, standard TPWD statewide regulations apply. There is no special slot or length limit recorded for Ivie.
Start on the Colorado River arm and find a channel swing. Rig a 10" Junebug PowerWorm on a Texas rig with enough tungsten to keep bottom contact in whatever depth you land on, and drag the 10 to 25 foot edge until you get bit. That single setup covers more of this lake, more of the year, than anything else in the box.
Give yourself a second area at the Concho and Colorado confluence, because if there is shad activity anywhere it will show up there, and that is where the Alabama rig earns its keep from fall through winter. Save the dam end for hot afternoons and deep vertical work.
Then match your effort to the level. Falling and low, like it has been, means channel edges and deeper structure. Rising means checking the back ends of the arms for freshly flooded brush and saltcedar, where bass will move up with the new water. Check the current reading before you tow, and let it decide which half of the lake you fish.
The most recent Texas Water Development Board reading was 43.9 percent full, with the surface at 1530.61 feet against a conservation pool of 1551.5 feet, so 20.9 feet down and falling. It changes everything about shoreline fishing. Cover that is prime at full pool is on dry ground, and the fish are compressed onto the Colorado and Concho river channels and main lake structure.
A 10" Berkley PowerWorm in Junebug on a Texas rig. Dragged on the Colorado and Concho channel ledges, it is the universal Ivie technique and it produces in every season. Carry 1 oz and 1.5 oz tungsten weights so you can fish it from 10 feet down to 35.
14.52 pounds. More useful for planning: 8 to 14 pound fish are realistic here every year, which is why the lake is treated as a world-class trophy fishery.
Yes. Zebra mussels are present in O.H. Ivie and full watercraft inspection and decontamination is mandatory before you leave the lake.
Check the water level first. The saltcedar-lined flats are the classic spawn pattern, flipped with 65 lb braid and a 1 oz Texas rig in 2 to 5 feet, but with the lake well below pool much of that cover may be out of the water. Fish the lowest band of cover at the current waterline instead.
Generally 25 to 40 feet, with 20 to 40 as the working range. Surface temps run 85 to 95 degrees. A 1 oz football jig and a 1 oz chrome jigging spoon on deep structure near the dam are the go-to presentations, and night fishing on a full moon is a good option.
Yes. Ivie does not shut down. Water in the 45 to 55 degree range groups shad into big schools at the Concho and Colorado confluence in 15 to 25 feet, and a 5-wire Alabama rig with 3.5" white swimbaits is the dominant winter presentation.
Variable, roughly 1 to 6 feet. Zebra mussels have increased clarity overall, but a red clay stain shows up after rain, so expect the two ends of the lake to look different on the same day.
