What to expect at Aurora Reservoir

Aurora Reservoir is a 1,400-acre impoundment on the South Platte River east of Denver, built primarily for water storage but managed as a public fishery by Colorado Parks and Wildlife. The lake holds walleye, northern pike, largemouth bass, channel catfish, and carp, with walleye and pike as the primary draws for anglers. The reservoir sits at roughly 5,280 feet elevation in semi-arid terrain, so water levels fluctuate seasonally—sometimes dramatically—based on municipal demand. Access is straightforward: a paved boat ramp, day-use parking, and a marina with rentals make it accessible to anglers of all skill levels, though the 25-mile-per-hour speed limit keeps the water relatively calm.

The fishery is strongest in spring and fall when water temperatures favor active feeding. Summer can be productive early and late in the day, but midday heat pushes fish deeper. Winter is possible but slow; the lake rarely freezes solid enough to support ice fishing. The reservoir's main appeal is proximity to Denver metro—about 20 minutes from downtown—and the chance to catch pike and walleye without a long drive to mountain reservoirs.

Key Takeaways

  • Walleye and northern pike are the most reliable species; walleye bite best at dawn, dusk, and night, while pike hunt actively throughout the day in spring and fall.
  • Water level changes throughout the year affect structure and fish location, so check current conditions before planning a trip.
  • A Colorado fishing license is required; you can purchase a one-day license on-site or online through Colorado Parks and Wildlife.
  • The boat ramp is open year-round during daylight hours, and the marina rents boats if you do not have your own.
  • Catfish bite well in summer and fall, especially at night, and require no special technique—simple rod-and-reel with live or cut bait works.

Walleye fishing: timing and technique

Walleye at Aurora Reservoir are most active during low-light periods—early morning, late evening, and throughout the night. They prefer structure: rocky points, drop-offs, and deeper channels where they can ambush prey. In spring (April through May), walleye move into shallower water to feed; focus on depths of 8 to 15 feet near the dam and along the eastern shoreline. By midsummer, they retreat to deeper water, typically 20 to 35 feet, where they remain until fall cooling brings them back to mid-depth zones.

Live bait—small shiners, minnows, or crawfish—fished on a simple slip-sinker rig works consistently. Jigging with small soft plastics (2 to 3 inches) in white, chartreuse, or natural colors is also effective, especially in spring. Trolling crankbaits along drop-offs produces fish but requires a boat. Night fishing with a headlamp and live bait under a bobber near the dam spillway can be productive in summer, though it requires patience and a willingness to fish after dark.

Northern pike: spring and fall peaks

Northern pike at Aurora Reservoir are aggressive predators that respond well to larger baits and lures. Spring (April and May) and fall (September and October) are peak seasons; water temperatures in the 50s to low 60s trigger active feeding. Pike hunt in shallow, weedy areas and along structure—fallen trees, rock piles, and the shallow flats near the inlet. In summer, they move deeper but remain active early and late in the day.

Large shiners (6 to 8 inches) or small bluegill on a quick-strike rig (two treble hooks spaced along the bait) is the standard live-bait approach. Casting large spoons (1 to 2 ounces) in silver or gold, or large soft plastics (4 to 6 inches) in bright colors, draws strikes from aggressive fish. Pike are not subtle; they hit hard and run fast, so use a wire leader or heavy fluorocarbon to prevent bite-offs. Expect fish in the 18- to 28-inch range; larger pike are present but less common.

Catfish and bass: summer and fall options

Channel catfish at Aurora Reservoir are abundant and underutilized by most anglers. They bite best in summer and fall, especially from late afternoon through the night. Catfish are not picky: chicken liver, cut shad, stink bait, or even hot dogs work. Fish the bottom in 15 to 25 feet of water, or along the dam face where deeper water meets structure. A simple three-way rig with a sinker on one line and a baited hook on another keeps bait on the bottom where catfish feed.

Largemouth bass are present but less abundant than pike and walleye. They respond to soft plastics, topwater lures, and live bait in spring and early summer. Focus on shallow, weedy areas and fallen timber. Bass fishing is secondary to the pike and walleye fishery here, but a few hours of casting can produce action if you enjoy the technique.

Access, regulations, and seasonal conditions

Aurora Reservoir is open to the public year-round during daylight hours. The main boat ramp is paved and well-maintained; parking is available at the day-use area. A Colorado fishing license is required for anyone 16 and older. You can purchase a one-day license on-site at the marina or online through the Colorado Parks and Wildlife website before you arrive. The current regulations allow two walleye per day (15-inch minimum), five pike per day (24-inch minimum), and 15 catfish per day (12-inch minimum). Regulations change, so check the current Colorado fishing brochure before you go.

Water level fluctuates significantly throughout the year, dropping in late summer and fall as Denver draws water for municipal use. This affects boat access and fish location; call ahead or check the Aurora Water Department website if you are concerned about ramp conditions. The lake rarely freezes solid enough for safe ice fishing, though winter fishing is possible during mild years. Spring (April and May) and fall (September and October) are the most reliable seasons for consistent action.

Marina services and boat rentals

The Aurora Reservoir Marina operates a boat ramp, fuel dock, and rental fleet. If you do not own a boat, you can rent a 16- to 20-foot motorboat by the hour or day. Rental rates vary by boat size and season; call the marina directly for current pricing. The marina also sells basic tackle, bait, and snacks. Kayak and canoe access is possible from the day-use area, though the 25-mile-per-hour speed limit means motorboats share the water—stay alert and keep to the shallows if paddling.

The marina is located on the north shore; the day-use area with parking and picnic tables is nearby. Restrooms are available at both locations. No overnight camping is permitted at the reservoir itself, but several campgrounds operate within 30 minutes in the metro area.

Getting there and planning your trip

Aurora Reservoir is located about 20 miles east of downtown Denver, accessible via Interstate 225 and Gun Club Road. From I-225, take the Gun Club Road exit and follow signs to the reservoir. The drive from central Denver takes 25 to 35 minutes depending on traffic. Parking is free at the day-use area. The reservoir is open from sunrise to sunset; night fishing is not permitted on the water itself, though some anglers fish from the shore after dark.

Plan for a half-day or full-day trip. Bring sunscreen, water, and layers—weather can change quickly in the metro area, and wind off the water can cool things fast. If you are new to the lake, consider hiring a guide for a half-day; several operate out of the marina and can teach you the structure and seasonal patterns. Check the Colorado Parks and Wildlife website for any temporary closures or restrictions before you leave.

Frequently Asked Questions

Can I fish from shore at Aurora Reservoir?

Yes. The day-use area has shoreline access, and catfish and some bass can be caught from the bank. Walleye and pike are more reliably caught from a boat, but shore fishing is a low-cost way to spend an afternoon. The dam spillway area is popular with shore anglers targeting catfish and walleye.

What is the best time of day to fish for walleye?

Early morning (one hour before sunrise to two hours after), late evening (two hours before sunset through dark), and throughout the night are most productive. Walleye have excellent low-light vision and hunt actively when the sun is low. Midday fishing is possible but slower.

Do I need a boat to fish Aurora Reservoir?

No, but a boat significantly increases your chances of catching walleye and pike. Shore fishing works for catfish and some bass. If you do not own a boat, the marina rents them by the hour or day, making it affordable for a single trip.

What should I do if the water level is very low?

Call the marina or check the Aurora Water Department website before you go. Low water can make the boat ramp unusable or change where fish are located. If the ramp is closed, you can still fish from shore or rent a kayak from the day-use area.

Are there any fish size or bag limits I should know about?

Yes. Walleye: two per day, 15-inch minimum. Pike: five per day, 24-inch minimum. Catfish: 15 per day, 12-inch minimum. Bass: five per day, 12-inch minimum. Regulations change, so check the current Colorado fishing brochure or the Parks and Wildlife website before you fish.
