What You'll Find at Reservoir Hill Park

Reservoir Hill Park is a small impoundment in the foothills west of Denver, managed by Colorado Parks and Wildlife. The reservoir holds warm-water species — primarily largemouth bass, bluegill, and channel catfish — in a setting that draws both locals and visitors looking for a shorter drive than the mountain lakes farther west. The park itself sits at roughly 6,000 feet, so the water stays cool enough through summer to support decent fishing, though it warms considerably by mid-July.

Access is straightforward: a paved parking area, a short walk to the water, and a developed shoreline with some structure. The reservoir is roughly 40 acres, making it manageable for a half-day trip. Most anglers fish from shore; a few bring small boats or float tubes, though the park does not have a boat ramp. The setting is residential in places — homes sit on the hillsides above — but the water itself feels removed from the immediate surroundings.

Key Takeaways

  • Reservoir Hill Park holds largemouth bass, bluegill, and channel catfish in a 40-acre impoundment west of Denver at 6,000 feet elevation.
  • Shore fishing is the primary access; no boat ramp exists, though small boats and float tubes are permitted.
  • Colorado Parks and Wildlife manages the park and enforces state fishing regulations, including a valid fishing license requirement.
  • Spring and early summer (April through June) typically produce the most consistent fishing before the water warms significantly.
  • The park has limited facilities — parking, restrooms, and a short walk to the water — so plan accordingly for a half-day outing.

Seasons and What to Expect Month by Month

Spring (April and May) is the strongest season. Water temperatures climb from the low 50s into the 60s, and bass begin moving shallow to spawn. Bluegill are active throughout the shallows, and catfish respond to live bait and cut offerings. Early morning and late evening produce the most strikes; midday fishing slows considerably even in spring.

Early summer (June) remains productive, though the bite becomes more selective as water temperatures push toward 70 degrees. Bass move deeper during the day and hunt more actively at dawn and dusk. Bluegill fishing stays steady in shallow areas with vegetation or structure. By late June, the reservoir begins to warm noticeably.

Mid-summer through early fall (July through September) is the slowest period. Water temperatures often exceed 75 degrees, and fish become lethargic during daylight hours. Night fishing for catfish and bass can work, but daytime shore fishing becomes challenging. Many anglers skip this window or focus on early morning sessions before the heat sets in.

Fall (October and November) brings a second window of opportunity. Water cools back into the 60s and 50s, and bass become active again. Bluegill fishing improves, and catfish feed more consistently. Winter (December through March) slows dramatically; ice occasionally forms, and most anglers do not fish the reservoir during this period.

Species, Tackle, and Techniques

Largemouth bass are the primary target. They respond to small crankbaits, soft plastics (4 to 6 inches), and topwater lures in early morning. Spinning tackle in the 6 to 7-foot range with 8 to 12-pound monofilament or braided line works well. Fish the shallow edges at dawn, then move to deeper water or structure as the sun rises. During spring spawning, sight-fishing in clear shallows can be productive if you move slowly and cast ahead of fish.

Bluegill are abundant and reliable, especially for anglers new to the water or bringing children. Small jigs (1/16 to 1/8 ounce), live crickets, or small spinners work consistently. A light spinning rod or even a cane pole is sufficient. Fish shallow vegetation, dock pilings, or rocky areas along the shoreline. Bluegill bite throughout the day, though early morning and late evening are best.

Channel catfish are present but less targeted than bass and bluegill. They respond to cut bait (chicken liver, shad), live shiners, or prepared stink baits. Fish the deeper areas near the dam or channel edges, especially at dusk and after dark. A medium spinning rod or light catfish rod with 12 to 20-pound line is appropriate. Catfish fishing is most productive in spring and fall.

Regulations and Licensing

Colorado Parks and Wildlife requires a valid fishing license for anyone 16 and older. A one-day license is available and costs less than a full-year license; both can be purchased online through the CPW website or at most sporting goods retailers in the Denver area. No special stamps or endorsements are required for Reservoir Hill Park.

Possession limits and size restrictions vary by species. Largemouth bass have a 15-fish daily limit with no minimum size. Bluegill and other panfish have a 50-fish combined daily limit. Channel catfish have a 10-fish daily limit. These regulations can change, so check the current CPW fishing guide before you go. Catch-and-release is always permitted and encouraged if you wish to fish longer than your limit allows.

The park is open dawn to dusk. Fishing is not permitted at night, which rules out dedicated night catfish sessions. Baitfish collection is not permitted; you must bring bait from outside the park or purchase it locally.

Access, Parking, and Facilities

Reservoir Hill Park is located in the foothills west of Denver, roughly 20 to 25 minutes from downtown depending on traffic. The address is 6800 West Alameda Avenue, Lakewood, Colorado. Parking is free and available in a paved lot near the entrance. The lot typically has space except on warm weekends in spring and early summer.

From the parking area, a short paved path leads to the water. The walk is less than 100 yards and is accessible for most fitness levels. The shoreline is developed with a mix of grassy banks, small rocky areas, and some vegetation. A restroom facility is available near the parking area.

The park has no concessions, boat ramp, or rental equipment. Bring your own tackle, bait, and water. A small cooler is useful for keeping bait fresh and storing any fish you keep. Shade is limited, so sunscreen and a hat are recommended, especially in spring and early summer.

What Makes Reservoir Hill Park Different

Reservoir Hill Park is not a destination lake — it is a local option for Denver-area anglers who want to fish without driving an hour or more to the mountains. The water is warm enough to support year-round fishing (though winter is slow), and the species mix is predictable. Bass and bluegill fishing in spring is solid, and the setting is pleasant without being spectacular.

The trade-off is size and solitude. At 40 acres, the reservoir can feel crowded on warm weekends, and the residential surroundings mean you are never far from houses or other people. If you are looking for remote backcountry fishing or trophy-sized fish, this is not the place. If you want a reliable half-day outing close to the city with decent bluegill and small to medium bass, Reservoir Hill Park delivers.

Nearby Alternatives

If Reservoir Hill Park is too crowded or the fishing is slow, several options lie within 30 to 45 minutes. Bear Creek Lake, also in the Denver metro area, is larger and holds similar species. Chatfield Reservoir, south of Denver, is bigger still and offers more structure and deeper water. Both require the same Colorado fishing license and follow the same regulations.

For a different experience, Cherry Creek Reservoir (northeast of Denver) is a larger impoundment with walleye, pike, and perch in addition to bass and panfish. The drive is roughly 45 minutes from downtown. All three alternatives are managed by Colorado Parks and Wildlife and offer more space and variety than Reservoir Hill Park, though they also draw more anglers on weekends.

Frequently Asked Questions

Do I need a boat to fish Reservoir Hill Park?

No. Shore fishing is the primary method, and most anglers fish from the developed shoreline. Small boats and float tubes are permitted but there is no boat ramp, so you would need to carry a kayak or canoe to the water. Most visitors fish from shore with spinning rods.

What is the best time of year to fish here?

April through June is the most productive window. Water temperatures are cool enough to keep fish active, and bass are spawning or feeding heavily. Early morning and late evening are best during this period. July through September is slow due to warm water.

Can I keep fish I catch?

Yes, within Colorado's daily possession limits. Largemouth bass have a 15-fish daily limit with no minimum size. Bluegill and panfish have a 50-fish combined limit. Channel catfish have a 10-fish daily limit. Check the current CPW fishing guide to confirm these limits have not changed.

Is there parking and how much does it cost?

Parking is free and available in a paved lot near the park entrance. The lot usually has space except on warm weekends in spring and early summer. There is no day-use fee to fish the reservoir.

What should I bring?

Bring your own tackle, bait, and water. A small cooler keeps bait fresh. Sunscreen and a hat are essential, especially in spring and early summer. The park has restrooms but no concessions or equipment rental, so plan accordingly for a half-day outing.
