THE FISHERY
South Boulder Creek at Eldorado Springs offers anglers a scenic fishing experience, with clear, fast-flowing waters and healthy trout populations nestled within the dramatic cliffs of Eldorado Canyon.
Fish Species
South Boulder Creek at Eldorado Springs is home to populations of wild brown and rainbow trout, with most fish ranging from 8-14 inches. Browns are the predominant species, and while the trout here are generally smaller, they are healthy, wild fish that provide consistent action, particularly in the more challenging pocket water and riffles.
Unique Fishing Conditions
This section of South Boulder Creek flows through the scenic Eldorado Canyon and offers a mix of shallow riffles, pocket water, and deeper pools. Spring and summer bring consistent hatches of caddis, blue-winged olives, and midges, providing good dry fly opportunities. Terrestrials such as ants and beetles work well during the warmer months, especially near the banks. Nymphing with smaller patterns (sizes 16-22), including midge and mayfly nymphs, is productive throughout the year, particularly in the deeper pools and seams.
Access and Regulations
Public access to South Boulder Creek at Eldorado Springs is excellent, with access through Eldorado Canyon State Park. The area is popular with both anglers and hikers, so early mornings or weekdays offer more solitude. There are no special regulations in this section, but catch-and-release is encouraged to protect the wild trout population. The creek can be affected by seasonal water flows, particularly during spring runoff, so checking water conditions before heading out is advisable.
TACTICS
AvidMax encourages anglers to explore their full repertoire on Boulder Creek:
Nymphing
Nymphing allows anglers to target trout feeding below the surface, with or without an indicator, making it an effective technique for covering deep runs and slow pools where fish are actively feeding on subsurface insects.
Dry Fly Fishing
Fishing with dry flies provides the ultimate surface experience, imitating adult insects and offering exciting visual strikes, particularly during hatches when trout are feeding on the water’s surface.
Streamer Fishing
Using streamers mimics baitfish and other larger prey, offering an aggressive approach that can entice bigger, predatory trout, especially when fishing deeper water or fast-moving currents.
SEASONS
Each season on South Boulder Creek brings unique joys and challenges for AvidMax anglers:
Spring
Spring runoff can increase water flows and create murky conditions, making larger nymphs like stoneflies or San Juan worms effective. Focus on fishing near the banks or in slower pools where trout seek refuge from faster currents.
Summer
Summer offers excellent dry fly action with caddis, PMDs, and terrestrials like ants and hoppers. Fishing early morning and late evening provides the best opportunities, especially during hotter mid-day hours.
Fall
Fall brings cooler water temperatures, making trout more active, with small mayflies and midges being effective patterns. Focus on deeper runs and pools as fish prepare for winter.
Winter
Winter fishing is slow, but trout can still be caught in deep, slow-moving water. Nymphing with small midges and baetis patterns during the warmest part of the day is the best tactic.
REMEMBER
South Boulder Creek at Eldorado Springs provides a picturesque fishing experience within a rugged canyon, making it a favorite among anglers seeking beauty and solitude. However, the creek’s smaller size and fragile ecosystem require responsible fishing to preserve its trout populations and natural habitat.
Water Conditions
Seasonal runoff and water diversions can affect the creek’s flow, especially in spring and early summer. Check the flow levels before heading out, as higher water can make wading more challenging and impact fishing conditions.
Regulations
This section may have specific catch-and-release regulations and restrictions on using only artificial flies and lures. Be sure to follow these rules to help protect the fishery and maintain healthy trout populations.
Safety
The steep canyon walls and rocky riverbed can make access and wading difficult, especially after rain. Wear proper wading boots with good traction and be cautious when navigating the creek, particularly in faster-moving or deeper sections.
