A still, cloudless night on the water, with a mirror surface most of the day and pressure leaking away. Expect most activity at Lost Lake around windblown banks where food collects. The strongest window is the evening. Make the first hour count and build on it. Autumn rewards covering water while the fish roam.

Lost Lake is set in Rio Grande County, Colorado. The setting is lake country bush on every side. A splashy cast here empties the swim; a quiet one owns it. Most waters listed here for Rio Grande County are larger. Del Norte lies 13 miles from the water. Beyond it, Monte Vista at 24 miles and Center at 27 miles. Rules here are straightforward: one county, one set of rules.
Open data we checked carries no depth for this water. The productive water is a rod length or two out, not a hundred. Still water like this holds fish on the edges rather than out in the open. Public occurrence data for Rio Grande County names white sucker, brown trout, rainbow trout, tench and common carp. County records show the wider picture rather than this one place. At Lost Lake the first feature you find is worth twenty minutes.
Temperature averages peak at 55°F in July and bottom out at 17°F in January. Seasons are distinct, and each one fishes differently. Ice-out usually falls in mid May, and the weeks after it fish hardest. Going by climate averages, expect open water from about mid May until roughly mid November. Look to early summer and the first cool weeks of autumn. That is the shape of the year on Lost Lake.
Access is not recorded for this water. Access points are not mapped for this water, which suits people who like quiet. For the trout, small spinners and a box of nymphs cover both approaches. Parking space is the usual limit rather than the bank itself. Barbless rules turn up on managed water more often than not. Million Reservoir, 5.1 miles away, makes the obvious fallback. Nothing on Lost Lake should be assumed from this page alone.
