Los Pinos River Below Vallecito Reservoir – April Fly Fishing Report: As of early April, the Los Pinos River below Vallecito Reservoir is experiencing spring conditions with variable flows due to reservoir releases. 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 Prince Nymphs, Copper Johns, and Pheasant Tails in sizes 12–18. 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 Skully Buggers 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 Los Pinos River below Vallecito Reservoir offers rewarding opportunities for anglers this April.

THE FISHERY
The Los Piños River below Vallecito Reservoir offers anglers a productive tailwater fishery, with steady flows and cold waters supporting excellent trout fishing in a beautiful, secluded mountain setting.
Fish Species
The Los Piños River below Vallecito Reservoir is known for its populations of brown, rainbow, and cutthroat trout, with browns being more dominant. Trout sizes typically range from 12-18 inches, with larger fish possible, especially during the fall when brown trout become more aggressive as they enter their pre-spawn phase.
Unique Fishing Conditions
As a tailwater fishery, the Los Piños River benefits from cold, consistent flows from Vallecito Reservoir, offering year-round fishing opportunities. The river features deep pools, runs, and riffles, making it ideal for both dry fly and nymph fishing. Spring and summer hatches of caddis, blue-winged olives, and stoneflies provide excellent dry fly action. During colder months or off-hatch periods, nymphing with small midges, caddis, and stonefly patterns (sizes 16-22) is effective. Streamers are productive in the fall for targeting larger browns.
Access and Regulations
Public access is available through the Los Piños River State Wildlife Area and other nearby public lands, providing several points for wade fishing. This section does not have specific Gold Medal Waters regulations, but catch-and-release is encouraged to preserve the quality of the fishery. Anglers should check flow conditions before heading out, as water releases from Vallecito Reservoir can fluctuate and impact fishing conditions and wading safety.
TACTICS
AvidMax encourages anglers to explore their full repertoire at Los Piños 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 Los Piños River brings unique joys and challenges for AvidMax anglers:
Spring
Spring runoff can lead to higher flows, but tailwater releases often provide fishable conditions. Nymphing with stoneflies and baetis patterns near slower pockets and deeper runs is effective during this time.
Summer
Summer brings excellent dry fly fishing with hatches of caddis, PMDs, and terrestrials like hoppers. Early mornings and late evenings provide the best action, especially in riffles and near undercut banks.
Fall
Fall is ideal for targeting larger brown trout as they prepare to spawn, making streamers and egg patterns highly effective. Focus on deeper pools and near structure where these aggressive fish hold.
Winter
Winter fishing is slower, but trout can still be caught by nymphing with small midge and baetis patterns in slower, deeper water. Target the warmest part of the day for the best results.
REMEMBER
The Los Pinos River below Vallecito Reservoir is a beautiful tailwater fishery, offering excellent trout fishing in a peaceful and remote setting. However, the fluctuating water levels and delicate ecosystem require anglers to practice responsible fishing and adhere to regulations to preserve this special fishery.
Water Conditions
Flows are regulated by releases from Vallecito Reservoir and can fluctuate significantly. Check the flow conditions before heading out, as higher releases can impact both fishing success and wading safety.
Regulations
Certain stretches of the Los Pinos may have catch-and-release or artificial flies and lures-only restrictions. Make sure to follow these regulations to help protect the trout population and maintain the quality of the fishery.
Safety
The rocky riverbed and cold, fast-moving water can make wading challenging, especially after releases from the reservoir. Wear proper wading boots with good traction, and exercise caution when navigating deeper sections or swift currents.
