1,872-acre reservoir near Ashland. The lake tops out around 75 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 1,852 acres, worked by 17.4 miles of shoreline, broken up by 3 islands. An index of 2.9 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 13% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 5.2 mi long by 1.6 mi wide at the broadest reach. It sits in Jackson County. Fish Lake sits 11 mi north — the closest neighbouring chart.
Spring rainbow trout on Howard Prairie Lake hold shallow, usually 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. The chart's best answer is Creek inflow — inflow / creek mouth, 13 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Creek inflow (13 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Creek inflow (13 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (14 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Old creek channel (13 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Main-lake point: a point around 14 ft that scores prime in fall. Best bite is early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (14 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (14 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Old creek channel (13 ft) | Blade bait, Jigging spoon |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 20 to 45 ft one. Start at Main-lake point. It's a point holding about 14 ft of water and rates prime come fall. The feeding windows run early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Willow Creek inflow (10 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (14 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (14 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (73 ft) | Blade bait, Hair jig |
