What You'll Find at Colvill Park
Colvill Park is a public access point on the Minnesota River in New Ulm, Brown County, offering boat launch and shore fishing for walleye, northern pike, and catfish. The park sits in a residential area near downtown New Ulm, making it one of the most convenient launch points for the lower Minnesota River. The Minnesota River here runs slower and deeper than upstream sections, creating habitat that holds fish year-round but peaks in spring and fall when water temperatures favor active feeding.
The park provides a single concrete boat ramp suitable for small to medium boats — nothing elaborate, but functional for jon boats, canoes, and modest recreational craft. Parking is available directly adjacent to the launch, and the grounds include picnic tables and basic facilities. This is a day-use park; there is no overnight camping.
Key Takeaways
- Colvill Park offers a concrete boat ramp and shore access on the Minnesota River in New Ulm, open year-round during daylight hours.
- Walleye and northern pike are the primary species; walleye fishing is strongest in spring (April through May) and fall (September through October).
- A Minnesota fishing license is required; no special stamps or permits are needed beyond the standard license.
- The Minnesota River at this location is slower and deeper than upstream sections, favoring live bait and jigs over fast-moving lures.
- Water levels and current can change rapidly after heavy rain; check conditions before launching, especially in spring.
Seasons and What to Expect
Spring (April through May) is the strongest walleye season at Colvill Park. As water temperatures climb from the 40s into the 50s, walleye move into shallower areas and feed more actively. Live minnows under a slip bobber or small jigs tipped with minnows work well in the deeper holes and along the channel edges. Northern pike are also active in spring, though they tend to be more scattered than walleye.
Summer (June through August) slows considerably. Water temperatures exceed 70 degrees, and walleye retreat to the deepest holes and shaded areas. If you fish summer, focus on early morning or evening, and work the deeper channel. Northern pike remain catchable but are less predictable. Catfish become more reliable in summer, especially at night with cut bait or stink bait.
Fall (September through October) brings a second strong walleye bite as water cools back into the 50s and 60s. Fish are more aggressive and less selective about bait presentation. This is also a good time for northern pike. By November, water temperatures drop into the 40s and below, and fishing becomes slower, though winter fishing is possible through ice if conditions allow.
Access, Parking, and Facilities
Colvill Park is located at 1 Colvill Park Drive in New Ulm, accessible from Highway 14 or local roads through downtown. The concrete boat ramp is straightforward to use and accommodates most small recreational boats. Parking is free and located immediately next to the ramp — typically 10 to 15 spaces, which is usually adequate except during peak summer weekends.
The park is open during daylight hours year-round. Facilities include picnic tables, a small shelter, and restrooms. There is no fuel, bait shop, or food service at the park itself; the nearest services are in downtown New Ulm, about a mile away. Cell service is generally reliable in the area.
The Minnesota River at this point is relatively narrow and manageable for small boats, but current can be swift after heavy rain or during spring snowmelt. Check water conditions before launching, especially in April and May. The ramp can become slippery when wet; wear appropriate footwear.
Species and Fishing Methods
Walleye are the primary target. They respond well to live minnows (shiners or shad) under a slip bobber positioned 4 to 8 feet deep, depending on water clarity and time of day. Small jigs (1/8 to 1/4 ounce) tipped with a minnow or leech are equally effective and allow you to cover more water. Early morning and evening are most productive, though walleye feed throughout the day in spring and fall. In summer, fish the deepest holes and the shadiest banks.
Northern pike are present but less predictable than walleye. They respond to larger minnows (4 to 6 inches), spinnerbaits, and crankbaits. Pike tend to hold near vegetation and woody cover; scan the banks and any submerged structure. Spring and fall are best; summer pike are less active in the slower, warmer water.
Catfish are underutilized at Colvill Park but are reliably present. Cut bait, chicken liver, or commercial stink bait fished on the bottom at night produces results. Catfish are most active in summer and early fall when water is warm.
Regulations and Licensing
Minnesota requires a valid fishing license for anyone 16 and older. You can purchase a license online through the Minnesota Department of Natural Resources (DNR) website, by phone, or at any authorized vendor. A one-day license costs less than a full-year license and is a good option if you fish infrequently.
Walleye and northern pike are subject to size and bag limits. As of the most recent regulations, the walleye limit is typically 6 fish per day with a 15-inch minimum size, though limits can vary by water body and season. Northern pike limits are usually 3 fish per day with a 24-inch minimum. Catfish have no size limit and a generous bag limit. Check the current Minnesota fishing regulations before you fish, as limits change annually and can vary by specific water body.
No special permits or stamps are required beyond the standard fishing license. The Minnesota River is open to public fishing, and Colvill Park is a designated public access point.
What Makes Colvill Park Different
Colvill Park's main advantage is convenience and location. It sits in a town with services nearby, making it accessible for a quick morning or evening trip. The Minnesota River at this point is slower and deeper than upstream sections, which means it holds fish more consistently and is easier to navigate for inexperienced boaters.
The downside is that the park is small and can feel crowded on summer weekends. The ramp is functional but basic, and there is no bait or tackle shop on-site. If you prefer a quieter experience or want more amenities, you may want to explore other Minnesota River access points upstream or downstream, though Colvill Park remains one of the most accessible options in the region.
Frequently Asked Questions
Can I fish from shore at Colvill Park?
Yes. The park has a small shoreline area where you can fish without a boat. Shore fishing is most productive near the boat ramp and along the immediate banks. A boat gives you access to deeper holes and more productive structure, but shore fishing is a viable option for walleye and catfish, especially in spring and fall.
What is the best time of day to fish here?
Early morning (sunrise to mid-morning) and evening (late afternoon through dusk) are most productive for walleye. Catfish feed throughout the night. Summer fishing is best in early morning or after sunset, when water temperatures are cooler and fish are more active.
Do I need a boat to fish Colvill Park?
No, but a boat significantly increases your chances. Shore fishing is possible, but the deeper holes and most productive structure require a boat to reach. If you do not own a boat, shore fishing or renting a small boat from a local outfitter are options.
What should I bring for a day at Colvill Park?
Bring a fishing license, appropriate tackle for walleye or pike (minnows, jigs, or lures), sunscreen, water, and a hat. If you are launching a boat, bring a life jacket and check that your boat is in working order. There are no bait shops at the park, so purchase minnows or tackle in New Ulm before you arrive.
Is Colvill Park open in winter?
The park is open year-round during daylight hours. Winter fishing is possible, though the Minnesota River does not always freeze solid enough for safe ice fishing. Check local conditions and ice thickness before attempting to fish through ice. Open-water fishing is possible in winter but is slower than spring and fall.
