Night
Grand County, Colorado, is where Griggs Reservoir sits. The setting is pine and birch. On water this small, stealth matters more than range. Our Grand County list holds plenty of bigger water. Some 4.2 miles away sits Kremmling, the nearest settlement. Beyond it, Granby at 24 miles and Vail at 25 miles. A county boundary sits nearby, which can matter for local access rules.
The records we hold are silent on depth, so plan to find it yourself. Look for the band where the shallows give up and the bottom falls away. Bays and points beat straight shoreline every time on water like this. Species logged across Grand County include black-spotted cutthroat trout, brook trout and rainbow trout. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. At Griggs Reservoir the first feature you find is worth twenty minutes.
Long-term averages put July at about 61°F and January near 16°F. The year runs cold to warm and back, with clear transitions. Count the season from break-up, usually late April. Averages place the thaw at late April and the freeze at late November. Early summer and early autumn carry the open-water season. Anyone fishing Griggs Reservoir regularly works to that calendar.
Whether the bank is open is not something our records settle. Mapping shows an empty shoreline: no ramp, no jetty, no marked entry. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Gates get locked out of season on water like this. Close seasons apply to some species and not others. Should this one be busy, Moore Reservoir is 3.1 miles off. Where Griggs Reservoir is concerned, a local answer beats a written one.
