Winter & getting in and out
CR 501 is a Level 1 plow priority and the dam sees about 85 inches of snow a year. Here's getting in and out.
County Road 501, the road to Vallecito Lake, is plowed all winter as a La Plata County Level 1 priority road: continuous all-weather access. It ices on the shady pitches before the highway does. The dam averages about 85 inches of snow a year (NOAA 1991–2020 normals). Colorado’s traction law covers US 160 and US 550, not CR 501.
CR 501 is a Level 1 priority road
This surprises people: the county plows CR 501 as a Level 1 road — “continuous all-weather access,” cleared before the school buses run. CR 500, 501A, and 502 are Level 2 (same-day target, first to slip in a big dump), and gravel roads get plowed after about 4 inches. The District V (Bayfield) road shop is (970) 382-6420.

Level 1 means maintained, not bare and dry. The road ices on the shady pitches and the switchbacks well before the highway does, so drive it like the mountain road it is.
A shovel, a blanket, and a headlamp live in the truck from Halloween to Easter — and you keep the gas tank above half all winter. The storm you get stuck in is never the one you planned for.
About 85 inches a year at the dam
Lake elevation gets roughly 85 inches a year at the dam (NOAA 1991–2020 normals) — about double what Durango gets, but nowhere near the 200-plus inches people quote. Those belong to the high country above the lake (the Weminuche SNOTEL sites), not the shoreline. Source: NOAA/NCEI climate normals, station USC00058582.
It's real winter — cold, clear, and snowy — but it's a high-desert mountain winter: storms come through and then the sun comes back. Check live conditions and road status before you head down the hill.
The traction law (and where it applies)
Colorado's traction law covers the state highways — US 160 and US 550 — not CR 501. When it's active you need all-wheel/four-wheel drive with at least 3/16-inch winter-rated tread, or chains / an approved traction device. Fines run roughly $50–$130, and $650-plus if you spin out and block the road (CDOT's own pages vary on the exact numbers). Source: CDOT traction law.
Up on CR 501 there's no statute — just physics. Good winter tires aren't optional for full-time life here. Time errands around the storm rather than through it: most systems clear within a day, and the county is plowing the whole time.
Outages, wood heat, and burn permits
Power is La Plata Electric Association, a member co-op; their live outage map is worth a bookmark. Winter outages do happen north of Bayfield, so most full-timers keep a backup — a generator, or a wood or pellet stove. New stoves must be EPA-2015-compliant, but there's no routine indoor-burning ban here.
Outdoor burning needs a free one-year burn permit from Upper Pine River Fire — issued seven days a week, including at Station 4 (North Vallecito), (970) 444-0030. Permits automatically suspend on Red Flag days, so always check the current fire status first. More in our Firewise guide. Source: upperpinefpd.org.
Sign up for LPC Alerts!
La Plata County's emergency notification system is LPC Alerts! — sign up at lpcgov.org/LPCAlerts. Save the numbers it calls from — (970) 385-8700 (calls) and 58339 (texts) — so a 2 a.m. evacuation or road-closure message is one you actually answer. It carries wildfire, flood, and winter-emergency notices.
