Recent Reports
Middle Fork of the South Platte River near Prince – April Fly Fishing Report: As of early April, the Middle Fork of the South Platte River near Prince is transitioning into spring conditions. Historically, this area becomes fishable as ice recedes and water temperatures rise, typically around this time of year. Anglers can anticipate hatches of midges and Blue-Winged Olives (BWOs) during warmer midday periods, providing opportunities for both nymphing and dry fly fishing. Effective nymph patterns include Pheasant Tails, Copper Johns, and RS2s in sizes 16–20. For dry fly enthusiasts, BWOs and midge patterns in sizes 18–22 can be productive during active hatches. Additionally, streamer fishing with patterns like Woolly Buggers and Sculpzillas can yield positive results, especially during overcast conditions. Employing light tippets (5x to 6x) and a stealthy approach is advisable due to the river’s clear water and wary trout. Focusing efforts during the warmest parts of the day, typically late morning to early afternoon, can enhance success rates. Overall, the Middle Fork of the South Platte River near Prince offers rewarding opportunities for anglers as spring progresses.

THE FISHERY
The Middle Fork of the South Platte at Prince offers anglers a tranquil fishing experience, with meandering waters and plentiful trout set against the scenic backdrop of Colorado’s rolling hills and mountain views.
Fish Species
The Middle Fork of the South Platte River near Prince is home to populations of wild brown, rainbow, and brook trout, with brown trout being the dominant species. Trout in this section typically range from 10-16 inches, and there is a chance to catch larger browns, especially during the fall pre-spawn period when they become more aggressive.
Unique Fishing Conditions
This section of the river offers a mix of pocket water, riffles, and deep pools, making it ideal for a variety of fly fishing techniques. The river tends to run cold and clear, providing good fishing conditions year-round. Summer and fall are the prime fishing seasons, with excellent dry fly opportunities during hatches of blue-winged olives, caddis, and midges. Nymphing with small midge, stonefly, and mayfly patterns (sizes 16-20) is effective throughout the year, particularly in deeper runs and seams.
Access and Regulations
Public access to the Middle Fork near Prince is available through multiple points along public land and trails. While there are no specific regulations for this section, anglers are encouraged to practice catch-and-release to help maintain the fishery’s health and sustainability. Seasonal water levels can vary depending on snowmelt and upstream reservoir releases, so anglers should check flow conditions before planning a trip for the best fishing experience.
TACTICS
AvidMax encourages anglers to explore their full repertoire on the Middle Fork of the South Platte River:
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 the Middle Fork of the South Platte brings unique joys and challenges for AvidMax anglers:
Spring
Spring runoff can cause higher flows, but nymphing with stonefly and baetis patterns near the banks and in slower pools can still be productive. Focus on areas where trout seek shelter from the faster current.
Summer
Summer offers excellent dry fly fishing with hatches of caddis, PMDs, and terrestrials like hoppers. Early morning and evening are the best times to fish, especially in the riffles and along undercut banks.
Fall
Fall is prime time for targeting brown trout during their pre-spawn, with streamers and egg patterns working well in deeper pools and runs. Focus on areas near structure where larger trout tend to hold.
Winter
Winter fishing can be slow, but small midge and baetis nymphs fished deep in slower-moving pools are effective. Fish during midday when the water temperature is slightly warmer and trout are more active.

REMEMBER
The Middle Fork of the South Platte River near Prince offers a scenic and rewarding fishing experience, with clear waters and healthy trout populations thriving in a high-country environment. However, this remote and delicate fishery requires anglers to fish responsibly and stay mindful of its alpine ecosystem.
Water Conditions
Seasonal runoff, particularly in the spring, can lead to high water flows that affect both fishing and wading conditions. Be sure to check the water levels before heading out, as early summer tends to bring more manageable flows.
Regulations
Certain sections of the Middle Fork near Prince may have specific regulations, such as catch-and-release requirements and the use of artificial flies and lures only. Always review the local rules to ensure compliance and protect the fishery.
Safety
The high-elevation setting means weather can change quickly, and the river’s rocky bottom can make wading difficult. Wear proper wading boots with good traction and pack layers to be prepared for sudden temperature changes or storms.
