What You'll Find at Castlewood Park

Castlewood Park sits on the New River in southwestern Virginia, about 20 miles south of Wytheville. The park is built around a 60-acre impoundment created by a low-head dam, and it holds smallmouth bass, muskie, catfish, and sunfish. The water is clear most of the year, which makes sight-fishing possible in summer and fall. The park itself offers a boat launch, picnic areas, and a small campground, making it a practical base for a day trip or overnight stay.

The New River above and below the dam holds different fish. The impoundment is shallower and warmer, favoring smallmouth and catfish. The tailwater below the dam runs colder and faster, which draws muskie and larger smallmouth, especially in summer. Most visiting anglers focus on the impoundment because access is easier and the fish are more predictable.

Key Takeaways

  • Castlewood Park's impoundment holds smallmouth bass year-round, with spring and fall offering the most consistent action.
  • The park has a public boat launch, but the impoundment is small enough that bank fishing from the dam or picnic areas is productive.
  • Muskie are present in the tailwater below the dam and in deeper sections of the impoundment, but they require specialized tackle and patience.
  • Virginia fishing licenses are required; check current regulations for bass size limits and daily creel limits before you fish.
  • The park charges a day-use fee and has limited facilities, so plan to bring your own food and water.

Seasons and What to Expect

Spring (March through May) is the most reliable time to fish Castlewood. Smallmouth move shallow to spawn in April and early May, and they bite aggressively on crankbaits, jigs, and soft plastics. Water temperatures climb from the 50s to the low 60s, and the impoundment can be crowded on weekends. Early morning and late afternoon produce the best bites.

Summer (June through August) slows the bite in the impoundment as fish move deeper and water temperatures reach the low 70s. The tailwater below the dam becomes more productive because the water stays cooler. Muskie fishing picks up in July and August, especially early and late in the day. Bank fishing from the dam can be good for catfish at night.

Fall (September through November) brings a second strong bite as water cools and smallmouth move back to shallower structure. October is often as good as spring. The impoundment clears up, and sight-fishing becomes possible. Muskie remain active through October.

Winter (December through February) is slow. Water temperatures drop into the 40s, and fish become lethargic. A few anglers fish for catfish and winter smallmouth, but success is inconsistent. The park remains open, but facilities may be limited.

Access, Parking, and Facilities

Castlewood Park has a public boat launch on the impoundment's north side, accessible from Virginia Route 52. The launch is a single-lane concrete ramp suitable for small to medium boats. Parking is available near the launch, and there is a day-use fee (the amount varies; check with the park office before you go). The park does not have fuel or bait sales on-site.

Bank fishing is possible from the dam itself and from picnic areas along the shoreline. The dam is accessible on foot and offers a good vantage point for sight-fishing in clear water. No special permission is needed to fish from the bank, but you must stay within park boundaries.

The park has a small campground with tent and RV sites, a picnic area with grills, and restrooms. There is no on-site restaurant or convenience store. Wytheville, about 20 miles north, has gas, groceries, and lodging. Cell service is spotty in the park itself.

What Tackle and Techniques Work

For smallmouth in the impoundment, bring a medium-power spinning rod and 6- to 8-pound monofilament or braided line. Crankbaits in shad patterns work well in spring and fall. Jigs (1/4 to 1/2 ounce) tipped with crawfish or soft plastics are effective year-round, especially around structure. Topwater lures produce strikes in early morning and late evening.

Muskie fishing requires heavier tackle: a 7-foot medium-heavy baitcasting rod, 20- to 30-pound braided line, and a wire or heavy fluorocarbon leader. Large swimbaits (6 to 10 inches), bucktail spinners, and crankbaits are standard. Muskie fishing is a numbers game—expect long periods between strikes. Most anglers fish the tailwater or the deepest sections of the impoundment.

Catfish bite well at night on chicken liver, cut shad, or commercial stink baits. Fish the dam or deeper holes in the impoundment. A simple rod and reel with a slip sinker rig works fine. Catfish are most active in summer and early fall.

Virginia Fishing Regulations at Castlewood

You must have a valid Virginia fishing license to fish Castlewood Park. Licenses are sold online through the Virginia Department of Wildlife Resources (VDWR) website, at sporting goods stores, and at some bait shops in Wytheville. A one-day license costs less than a full-year license if you are visiting briefly.

Smallmouth bass have a minimum size limit of 12 inches and a daily creel limit of five fish. Muskie have a minimum size of 40 inches and a daily limit of one fish. Catfish have no size limit and a daily creel limit of 25 fish. Regulations can change, so check the VDWR website or call the Wytheville office before you fish to confirm current rules.

The park itself has no special fishing restrictions beyond state law. You may fish from sunrise to sunset, though night fishing for catfish is permitted. No explosives, poisons, or electrofishing are allowed.

When to Go and How to Plan

Plan a trip for April or May if you want the best chance at smallmouth. October is nearly as good and often less crowded. If you are targeting muskie, July through October offers the highest probability of a strike, though success is never may provide.

A day trip works well if you live within two hours of Wytheville. Arrive early (before 8 a.m.) to secure a parking spot and avoid the afternoon crowd. Bring sunscreen, water, and snacks—the park has no food vendors. If you are camping, reserve a site in advance during peak season (April through October).

The New River can rise quickly after heavy rain, which can make the impoundment murky and the tailwater dangerous. Check the water level and weather forecast before you leave home. Summer thunderstorms are common; plan to be off the water by mid-afternoon.

Nearby Fishing and Lodging

The New River extends for miles above and below Castlewood Park. Anglers often fish the tailwater below the dam for muskie and larger smallmouth. Access to the tailwater is limited, but a few pull-offs along Route 52 allow bank fishing. The river upstream from the park is less developed and holds smallmouth and sunfish, though access requires permission from private landowners.

Wytheville, 20 miles north, has chain hotels, a few local motels, and restaurants. The town is a crossroads on Interstate 77, so lodging is available but can fill up on weekends. Grayson Highlands State Park, about 30 miles north, offers additional camping and hiking if you want to extend your trip.
