Vallecito through the years

One little valley with a long history — the Ute homeland, a New Deal dam that drowned the old ranches to build the lake, and the fishing, hiking, wildflowers, wildlife, and dark skies that draw people back today.

The Ute homeland — the “little valley”

Long before it was a reservoir, this was Nuche country. Vallecito — Spanish for “little valley” — sits in the ancestral homeland of the Weeminuche band of the Ute people, the same name carried today by the Weminuche Wilderness that rises just above the lake. The Utes wintered in sheltered river valleys like the Pine (Los Piños) and followed the elk and the ripening berries into the high country each summer — a seasonal round they walked for thousands of years.

By treaty in 1868 the Utes held most of western Colorado; the Brunot Agreement of 1873 stripped away the mineral-rich San Juans, and the Southern Ute Reservation was drawn along the New Mexico line just south of here. That history still runs through the water: the Southern Ute Tribe holds a major share of the Pine River Project that built Vallecito, and tribal lands downstream are irrigated by its releases. These archival portraits are of Ute and Southern Ute people of that era — honest to the heritage of this place, not claimed to be photographed at the lake.

The dam & the New Deal

The lake is younger than the highway to it. In 1937 the New Deal authorized a Bureau of Reclamation dam on the Pine River; ground broke on May 14, 1938, and crews — including Depression-era labor — moved 3.7 million cubic yards of earth to raise a 162-foot dam, finishing in March 1941. An Army Corps engineer, Major C. A. Burns, photographed the whole build; those original prints survive at Fort Lewis College's Center of Southwest Studies.

What the water covered is part of the story too: the new reservoir drowned the valley floor — homesteads, hayfields, and the old wagon road — to store irrigation water for some 45,000 acres of farms plus 18,500 acres of Southern Ute land downstream. Today the dam is operated for flood control and irrigation, and the “level falling through late summer” you see on our conditions page is simply that 1941 promise being kept, one release at a time.

Old Vallecito & early families

After the Homestead Act, settlers drifted up the Pine River valley and built ranches where the creeks came together — the same bottomland that's now under the lake. Two of them are still on the map: John T. Graham and Thomas Wilson each have a creek named for the homestead they worked on the east side of today's reservoir. Cattle, hay, and hard winters; a one-room school; a chapel that began as gospel singing around a piano at Lost Creek Lodge in 1951.

Those families' descendants still ranch and run businesses around the lake, which is exactly why the best old photographs aren't in a federal archive — they're in shoeboxes and at the Pine River Library. We're working to feature a few with permission and full credit.

The lake today — out on the water & the trail

Vallecito is a lake people use: pontoons and fishing boats off the marina, kayaks and paddleboards in the early calm, six Forest Service campgrounds in the pines, and trailheads at the north end that walk you straight into the Weminuche Wilderness — Colorado's largest, nearly half a million acres. Seven gamefish swim here, kokanee salmon are the headliner, and a twenty-pound pike is the trophy.

Wild & scenic — the country around the lake

Step away from the water and the wild takes over fast. Elk and mule deer move through the aspen; black bears work the oak brush in fall (lock up the cooler); moose have returned to the willow bottoms; bald eagles winter over the lake and ospreys dive it all summer. The Weminuche even holds reintroduced lynx and Rocky Mountain bighorn. The wildlife photos below are of species that live here, honestly credited; the scenery is the country around the lake.

Wildflowers — the high-country bloom

From snowmelt through August the meadows above Vallecito put on one of Colorado's great wildflower shows. Lower down, the Colorado blue columbine — the state flower — nods in shady aspen glades alongside scarlet Indian paintbrush and purple lupine. Climb into the Weminuche's wet basins and you'll find mountain bluebells, elephant heads, marsh marigold, and, on the highest tundra, the sunflower-faced old-man-of-the-mountain. Peak bloom is usually mid-July, a couple of weeks later the higher you go.

Photos we need

This gallery grows with the community. We're especially after: the Vallecito Creek bridge, the accessible fishing pier, glass-calm dawn at the marina, alpenglow from CR 501, a kid netting perch off the dock, Lake Eileen aspens in late September, and the Milky Way over Middle Mountain.
