Recent Reports
North Platte River – Northgate Canyon – April Fly Fishing Report: As of early April, the North Platte River in Northgate Canyon is transitioning into spring conditions. Recent reports indicate that the canyon section remains frozen, with expectations of thawing in the coming weeks. As ice recedes, 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 may 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 North Platte River in Northgate Canyon offers promising opportunities for anglers as spring progresses.

THE FISHERY
The North Fork of the South Platte River at Northgate Canyon provides anglers with a rugged and remote fishing experience, where steep canyon walls and fast-moving waters create an exciting and challenging environment for pursuing trout.
Fish Species
The North Fork of the South Platte River near Northgate Canyon is home to healthy populations of brown and rainbow trout. Browns are the dominant species in this section, with trout typically ranging from 12-18 inches. Larger browns are possible, particularly during the fall when pre-spawn activity increases their aggression.
Unique Fishing Conditions
Northgate Canyon offers a rugged and scenic environment with fast-moving riffles, deep pools, and pocket water, making it ideal for both dry fly fishing and nymphing. The river sees seasonal changes in flow, with spring runoff creating higher water levels and summer through fall offering more manageable conditions. Blue-winged olive and caddis hatches in the summer provide excellent dry fly opportunities, while nymphing with stonefly, midge, and mayfly patterns (sizes 16-20) is productive year-round. Streamers can be particularly effective in the fall when targeting larger, aggressive browns.
Access and Regulations
Public access to North Fork near Northgate Canyon is somewhat limited due to the canyon’s rugged terrain, but there are access points available along trails and public lands. While not under specific Gold Medal Waters regulations, anglers are encouraged to practice catch-and-release to preserve the fishery’s health. Due to the river’s steep canyon walls, water flows can vary significantly, so checking flow conditions before heading out is recommended, especially during spring runoff when wading may be difficult.
TACTICS
AvidMax encourages anglers to explore their full repertoire on the North 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 North Fork of the South Platte River brings unique joys and challenges for AvidMax anglers:
Spring
Spring runoff can lead to high, fast water, but nymphing with stonefly and baetis patterns in slower eddies and deeper runs is effective. Focus on areas near the banks where trout seek refuge from stronger currents.
Summer
Summer offers excellent dry fly fishing with hatches of caddis, PMDs, and terrestrials like hoppers. Fish early mornings and late evenings in riffles and pools for the best dry fly action.
Fall
Fall is ideal for targeting aggressive brown trout as they prepare to spawn, making streamers and egg patterns highly effective. Focus on deeper runs and pools where these larger fish hold.
Winter
Winter fishing is slower, but trout can still be caught in deeper, slow-moving water using small midge and baetis nymphs. Target the warmest part of the day when trout are more active.

REMEMBER
The North Fork of the South Platte River near Northgate Canyon offers a rugged and rewarding fishing experience, with clear waters and beautiful scenery. Its remote and pristine nature requires anglers to practice ethical fishing and take care of the surrounding environment to preserve this wild fishery.
Water Conditions
Flow levels can vary due to runoff or water diversions, especially in the spring. Always check current water conditions before heading out, as higher flows can make wading dangerous and impact fish behavior.
Regulations
This section may have special regulations, including catch-and-release or restrictions on artificial flies and lures. Familiarize yourself with these rules to ensure compliance and help protect the fishery.
Safety
The rugged terrain and swift currents, particularly in Northgate Canyon, can make wading hazardous. Use caution, wear proper wading gear with good traction, and be mindful of your surroundings, especially in deeper or faster-moving water.
