Low, flat cloud sitting over the water, with mild air moving in from the W with pressure climbing. Most of the action on Monument Lake should come off bays that hold the day's warmth. Make the morning the heart of the trip. A careful, quiet approach will out-fish a busy one. Biting air and slow fish: small baits, long pauses.

Monument Lake stands in Garfield County, Colorado. The ground around here is pine and birch. Surface area runs to about 21 acres — small enough to read in one session. The closest town, Glenwood Springs, is 11 miles distant. The big place round here is Boulder, 112 miles distant. More in the same country: Duck Lake at 0.6 miles, 1 mile out stands Dry Lake, Grizzly Lake at 1.2 miles, 2.3 miles out stands Bugle Lake and Blue Lake at 2.4 miles. The nearest boundary is a fair way off.
Depth figures are not published for this one. On a natural lake the weed line and the shelf beyond it do the work. Read the surface for the wind lane, then fish the edge of it. Open biodiversity records for Garfield County list cutthroat trout, rainbow trout and brown trout. Take it as the county picture rather than a promise for this water. Monument Lake gives up more to patience than to distance.
The year swings from about 14°F in January to roughly 53°F in July. Spring and autumn carry the fishing; summer and winter test it. Once it clears, about late May, the fishing comes on quickly. The season between ice runs from about late May to early November. Look to early summer and the first cool weeks of autumn. Monument Lake runs to its own calendar within the local pattern.
The access position is unclear from public sources. Mapping shows an empty shoreline: no ramp, no jetty, no marked entry. For the trout, small spinners and a box of nymphs cover both approaches. Take the rules with you rather than trusting memory. Access can change hands, so last year's answer may not hold. Duck Lake sits 0.6 miles off and takes the overflow. Confirm access to Monument Lake locally before you travel.
