Man Fly Fishing In The Valles Caldera Preserve

Valles Caldera Preserve (New Mexico) — Fly Fishing Overview

• Location: High-elevation volcanic caldera in northern New Mexico, near Los Alamos and Jemez Springs.

• Waters: Small streams (e.g., Jemez River headwaters and tributaries like San Antonio Creek), ponds, and high-mountain meadow runs. Water levels vary seasonally.

• Species: Primarily rainbow and brown trout; occasional cutthroats. Fish tend to be wild or lightly pressured.

• Best seasons: Late spring through early fall. Snowmelt can make spring fishing high and turbid; summer and early fall offer clearer water and good insect hatches.

• Access & regulations: Preserve has guided-fishing access zones and may require permits, reservations, or guided trips during certain periods to protect habitat. Check current Preserve rules and catch-and-release areas before visiting.

• Recommended gear & tactics: Lightweight 3–5 weight rods, floating lines, light nymphs, dry flies, and small streamers. Match local mayflies, midges, and caddis patterns. Stealth and long leaders matter in clear meadows.

• Conservation notes: The Preserve emphasizes habitat protection and restoration; follow leave-no-trace principles, respect closures, and follow barbless-hook policies if required.
