THE FISHERY
The Rio de Los Piños River at Ortiz offers anglers a secluded and scenic fishing experience, with cold, clear waters and healthy trout populations flowing through the quiet, open landscapes of southern Colorado.
Fish Species
The Rio de Los Piños near Ortiz is known for its populations of wild brown trout, rainbow trout, and the occasional cutthroat trout. Browns dominate this section, with fish commonly ranging from 10-16 inches, though larger trout are possible, especially during the fall when browns enter their pre-spawn phase.
Unique Fishing Conditions
This section of the Rio de Los Piños offers diverse water conditions, including riffles, deep runs, and slow pools, providing opportunities for both nymphing and dry fly fishing. The river runs clear and cold, making it an excellent summer and fall fishery. During these seasons, hatches of blue-winged olives, caddis, and terrestrial patterns such as hoppers and ants provide strong dry fly action. Nymphing with midge and mayfly patterns (sizes 16-20) is productive year-round, especially in deeper pools.
Access and Regulations
Public access to the Rio de Los Piños near Ortiz is good, with multiple points available on public lands. The river offers a more remote, less pressured experience, making it ideal for anglers seeking solitude. There are no special regulations in this section, but practicing catch-and-release is encouraged to preserve the wild trout population. Seasonal water flows can vary, particularly during spring runoff, so checking flow conditions before heading out is recommended for optimal fishing.
TACTICS
AvidMax encourages anglers to explore their full repertoire on the Rio de 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 Rio de Los Piños brings unique joys and challenges for AvidMax anglers:
Spring
Spring runoff can lead to high, fast-moving water, making nymphing with larger patterns like stoneflies and San Juan worms effective. Focus on slower eddies and pockets where trout seek refuge from the strong currents.
Summer
Summer brings ideal dry fly conditions with hatches of caddis, PMDs, and terrestrials like hoppers and ants. Fish early mornings and late evenings in riffles and along undercut banks for the best dry fly action.
Fall
Fall is prime time for targeting aggressive brown trout as they prepare to spawn, making streamers and egg patterns effective choices. Focus on deeper pools and near structure where these larger fish hold.
Winter
Winter fishing can be slower, but trout can still be caught by nymphing with small midges and baetis patterns in deeper, slower water. Target the warmest part of the day for the most productive fishing.

REMEMBER
The Rio de Los Piños at Ortiz is a hidden gem, offering anglers a tranquil fishing experience with wild trout in a remote setting. Its pristine environment requires special care, so practice responsible fishing to help preserve this untouched fishery.
Water Conditions
The river can be affected by seasonal runoff, particularly in spring and early summer, which can lead to high, fast flows. Check water conditions before heading out, as lower flows during late summer and fall offer the best fishing opportunities.
Regulations
Certain sections may have catch-and-release requirements and artificial flies and lures-only restrictions. Be sure to review and follow local regulations to maintain the health of the trout population and protect this pristine waterway.
Safety
The remote location and rugged terrain mean you’ll need to be well-prepared with proper gear and supplies. The river’s rocky bed and swift currents require caution when wading, so wear proper wading boots and use extra care in faster sections.
