What You'll Find at Acme Dam

Acme Dam holds a solid mix of smallmouth and largemouth bass, channel catfish, and occasional carp across a 200-acre pool that runs narrow and deep through rocky foothills. The water stays cool enough year-round to support smallmouth, which means spring and fall produce the most consistent action, but summer nights and winter afternoons both have their moments. The dam itself—a low-head structure—creates current breaks and depth changes that concentrate fish, especially in the tailrace below the spillway.

Access is straightforward: a public boat ramp sits on the north shore, and a gravel parking area holds about a dozen vehicles. Bank fishing is possible along the upper pool near the ramp and from a few spots on the south bank, though the shoreline is steeper and rockier than most Northeast impoundments. The lake is managed by the county water authority, and a day-use permit costs a few dollars—available at the gatehouse or online through their website.

Key Takeaways

  • Smallmouth bass dominate the rocky structure near the dam and along the main channel; largemouth hold in the shallower, weedier upper pool.
  • Spring (April through May) and fall (September through October) produce the most reliable catches, with water temperatures between 55 and 70 degrees.
  • The tailrace below the dam holds catfish year-round and is accessible by foot from the parking area; this is the easiest bank-fishing option.
  • A day-use permit is required and can be obtained at the gatehouse or through the county water authority's online system before you arrive.
  • The boat ramp is usable year-round, but water levels drop in late summer, so check current conditions with the water authority before launching a deep-draft boat.

Spring Fishing: April Through May

Spring is when Acme Dam fishes best. Water temperatures climb from the low 50s into the mid-60s, and both smallmouth and largemouth move shallow to spawn. Largemouth congregate in the upper pool where fallen timber and aquatic vegetation provide cover; work a 1/4-ounce jig tipped with a crawfish imitation or a 4-inch soft plastic around deadfalls and weed edges. Smallmouth scatter along the rocky banks and drop-offs closer to the dam, where they're more aggressive on small crankbaits (1.5 to 2 inches) and tube jigs in brown or green patterns.

The tailrace below the dam is particularly productive in spring because the current brings cooler, oxygenated water that smallmouth prefer. Fish the current seams with a 3/16-ounce jig or a small spinnerbait, working the edges where fast water meets slack water. Early morning and late afternoon are most reliable, though overcast days can produce all day.

Summer and the Tailrace Catfish Run

By June, the main lake warms into the high 70s, and largemouth retreat to deeper weed beds and the thermocline. Smallmouth become less predictable, though early morning topwater can still produce near the dam. The real summer opportunity is catfish in the tailrace. Channel cats move into the current below the spillway to feed on baitfish and organic matter washed through the dam, and they stay active from dusk through the night.

Fish the tailrace with live bluegill or cut shad on a simple three-way rig or a slip sinker setup, anchored in the slower water just outside the main current. The tailrace is accessible by walking downstream from the parking area—about a quarter-mile on a maintained path. Bring a headlamp, a cooler, and patience; catfish fishing here is a sit-and-wait game, but a 15- to 25-pound channel cat is not uncommon on a good night.

Fall: The Second Peak Season

September and October bring the second-best fishing of the year. Water temperatures drop from the high 70s back into the 60s and low 50s, and both smallmouth and largemouth become aggressive again as they feed heavily before winter. Largemouth move back into the upper pool and shallower structure; smallmouth concentrate near the dam and along the main channel drop-offs.

Fall is an excellent time for topwater fishing. Early morning and late afternoon, throw poppers and walking-stick baits along the rocky banks near the dam and around any visible structure. Smallmouth will chase these aggressively. For a more methodical approach, work a 1/2-ounce jig-and-craw or a 3-inch soft plastic along the bottom in 8 to 15 feet of water. The transition from September to October is particularly good; water is still warm enough for active feeding but cool enough to push fish into predictable holding areas.

Winter Fishing and Low-Water Periods

Winter at Acme Dam is quieter but not empty. Water temperatures drop into the 40s, and both bass species move deep and slow down considerably. Smallmouth hold tight to the dam structure and the deepest parts of the main channel, 20 to 30 feet down. Fishing is slow, but a small jig (1/8 ounce) or a drop-shot rig fished vertically can produce. Afternoon hours are usually better than morning because the sun warms the water slightly.

Late summer (August and September) brings another consideration: water levels drop as the county draws down the reservoir for irrigation and municipal supply. The boat ramp becomes shallower, and some of the upper pool structure becomes inaccessible. Check the water authority's website or call ahead before launching; they post current levels and any restrictions. Bank fishing in the tailrace remains reliable year-round because water is released continuously through the dam.

Tackle and Technique for Acme Dam

Smallmouth bass respond best to small, natural-looking presentations. A 6-foot medium-light spinning rod with 6- to 8-pound fluorocarbon works well for jigs, tubes, and small crankbaits. Largemouth in the upper pool benefit from slightly heavier tackle—a 6.5-foot medium rod with 8- to 10-pound braid—because you'll be fishing around wood and vegetation. For catfish in the tailrace, a 7-foot medium-heavy rod with 12- to 15-pound mono or braid is standard; catfish don't require finesse, but they do require backbone.

Color matters less at Acme Dam than structure and timing, but brown, green, and black patterns work year-round for smallmouth. Largemouth respond to brighter colors (chartreuse, white) in stained water and natural colors (green pumpkin, brown) in clearer conditions. The water here is typically clear to slightly stained, so start with natural patterns and adjust if you're not getting strikes.

Access, Permits, and Practical Details

The public boat ramp is located on the north shore, accessible via County Road 47. Parking is free with a day-use permit, which costs a small fee and is valid for the calendar day. You can purchase a permit at the gatehouse (staffed 8 a.m. to 5 p.m. most days) or online through the county water authority's website before you arrive. The ramp is paved and well-maintained, with a courtesy dock for loading and unloading gear.

Bank fishing is best in the tailrace below the dam, where a gravel path leads downstream from the parking area. No permit is required for bank fishing, but the area is day-use only—no overnight camping. The upper pool has a few accessible bank-fishing spots near the ramp, but they're limited and often crowded on weekends. Respect private property; much of the shoreline is privately owned.

The lake is open year-round, but winter access can be limited by snow or ice. Call the water authority before a winter trip to confirm the ramp is clear. Gasoline motors are allowed, but a 10 mph speed limit is enforced in the upper pool to protect the shoreline and reduce erosion.

Frequently Asked Questions

What's the best time of year to fish Acme Dam?

Spring (April through May) and fall (September through October) are most productive. Water temperatures between 55 and 70 degrees trigger aggressive feeding in both smallmouth and largemouth. Summer catfish fishing in the tailrace is also excellent if you're willing to fish at night.

Can I fish from the bank, or do I need a boat?

Bank fishing is possible, especially in the tailrace below the dam, which is accessible by foot from the parking area. The upper pool has limited bank access near the ramp. A boat gives you more options and lets you reach deeper structure, but it's not required.

Do I need a fishing license at Acme Dam?

Yes, a state fishing license is required. The day-use permit for the lake itself is separate and covers parking and access; it does not replace your fishing license. Both are inexpensive and available online or at the gatehouse.

What should I do if the water level is low?

Check the county water authority's website or call ahead to confirm current levels before launching a boat. The ramp becomes shallower in late summer, and some upper pool structure becomes inaccessible. Bank fishing in the tailrace is unaffected by water level changes.

Are there any restrictions on what I can keep?

State bass and catfish regulations apply. Check your state's current size and bag limits before you fish; these change periodically. The water authority's website usually posts a summary of local rules at the gatehouse.
