Lake Agnes, Colorado: Fishing Spots and Seasons

• Overview

  Look for Lake Agnes in Routt County, Colorado. The setting is lake country bush on every side. It runs to roughly 106 acres — big enough to hold fish away from the bank, small enough to learn. Around 1.6 miles of margin, front to back. It ranks high for size among our Routt County listings. Steamboat Springs lies 15 miles from the water. The nearest city of size is Boulder, 74 miles away. Rules here are straightforward: one county, one set of rules.

• Where to Fish on Lake Agnes

  Depth figures are not published for this one. The shallow end warms first and pulls fish in ahead of the rest. Look for the band where the shallows give up and the bottom falls away. County-wide records name brook trout, cutthroat trout, rainbow trout and mountain whitefish. Those are county-wide records, so not every one of them will be in this water. On Lake Agnes that means starting tight and working out.

• Seasonal Patterns

  Seasonal averages run from 18°F in January up to 55°F in July. Cold locks it up for a good stretch each year. Ice fishing carries the winter, and the water opens about mid May. Expect the water usable from around mid May until roughly mid November. Late spring and early autumn carry the year between them. Lake Agnes fishes to that pattern most years.

• Tackle & Baits

  Nothing in our records says who may fish here. This is a natural basin, not a dammed one. Public mapping records no formal access here, so plan for a walk and soft ground. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Check whether a boat is allowed before you tow one. Some stretches are reserved and marked as such on the ground. If the gate is shut, Lily Lake at 0.7 miles is the nearest alternative. Signs at Lake Agnes carry more weight than any list.
