This Adams County lake logs more bird species than anywhere else in Colorado

It’s only 20 minutes from the city

Twenty minutes northeast of Denver, past the suburbs and the strip malls, the land opens up and goes quiet.

Barr Lake State Park covers 2,715 acres in Adams County, and at its center sits a 1,950-acre reservoir ringed by cottonwoods and marsh.

More than 371 bird species have been recorded here, more than anywhere else in Colorado. Bald eagles nest on the south end of the lake every year.

The place has been pulling people in since 1977, and once you see what’s out there, you’ll understand why.

Before the reservoir, bison roamed this ground

Long before there was a lake here, this low stretch of Colorado prairie was a bison wallow, a place where buffalo and American Indians gathered for generations.

That changed in 1886 when construction began on the Burlington Canal, pulling water from the South Platte River into the basin. The Oasis Dam was expanded in 1908, and the reservoir took shape.

For more than 70 years after that, Denver’s untreated wastewater drained into it. The flood of 1965 flushed the lake clean, and Colorado Parks and Wildlife took over a recreational lease in 1975.

This stretch of sky is a major bird highway

Barr Lake sits directly on North America’s Central Flyway, one of the continent’s main migration corridors running between breeding grounds in the north and wintering grounds in the south. That geography is why the bird list here runs so long.

In a single season, you can see American white pelicans, double-crested cormorants, great blue herons, sandhill cranes, grebes, and dozens of duck species moving through. Red-winged blackbirds crowd the marsh edges.

Geese fill the shallows. The lake acts like a magnet, and the birds know it.

Bald eagles have nested here since 1986

A pair of bald eagles first set up a nest at Barr Lake in 1986, the same year the park installed its first nesting basket to support them. Eagles have returned to the wildlife refuge every year since.

Over the decades, those nests have produced more than 59 young eagles.

The Bird Conservancy of the Rockies launched its Bald Eagle Watch volunteer program in 1988 to monitor the birds, and every February, the park holds a free Bald Eagle Festival with activities for families.

It’s one of the few places near a major city where you can watch nesting bald eagles from a boardwalk.

Walk the boardwalk out over the wildlife refuge

From the Nature Center, a 1.3-mile walk brings you to the Gazebo Boardwalk, which reaches out over the southern wildlife refuge.

Gazebos and benches line the boardwalk, and a spotting scope lets you look straight into the rookery without disturbing the birds.

Several wildlife observation stations are positioned around the park at angles that keep you screened from the nesting areas.

If walking isn’t your plan, the Eagle Express runs on weekends from mid-May through September, a 13-passenger motorized cart with a naturalist guide leading the way along the trails.

Flat trails that loop the whole lake

The main route here is the 8.8-mile Barr Lake Perimeter Trail, a flat loop around the entire reservoir open to hikers, bicyclists, and horseback riders.

The park has 12 miles of trails in total, none of them technical.

Shorter options include the Niedrach Nature Trail, a quick loop from the Nature Center that crosses a boardwalk along the lakeshore, and the Prairie Welcome Trail, which heads east into open prairie for just over a mile.

The Dam Crest Trail runs across the top of the dam but is off-limits to horses. One tip: bring thorn-proof tires if you’re riding, because the unpaved paths have thorns.

Cast a line on the north half of the lake

Fishing runs along the north shore, where ADA-accessible piers sit at the water’s edge and a boat ramp opens April 1 each season.

The lake is stocked with channel catfish, largemouth and smallmouth bass, rainbow trout, walleye, bluegill, wiper, and tiger muskie. You’ll need a valid Colorado fishing license.

In winter, ice fishing is allowed when conditions permit.

The southern half of the lake is a designated wildlife refuge, so fishing there is off-limits, as are the irrigation canals that ring the park.

Take a boat out, but know the rules first

The north half of the lake is open to sailboats, hand-propelled craft, and motorized boats of 10 horsepower or less with electric trolling motors.

Before you launch, every motorized boat goes through an Aquatic Nuisance Species inspection at the ramp. Worth noting: Barr Lake is an irrigation reservoir, and water levels fall through the summer.

The lake can be closed to boating entirely when levels drop too low, so check conditions before you haul a boat out there. Swimming, diving, and wading are not allowed anywhere on the water.

Stop into the Nature Center before you head out

The Barr Lake Nature Center sits near the south parking lot and has displays on the park’s wildlife, with a naturalist available to answer questions.

It’s open Tuesday through Sunday, 9 a.m. to 4 p.m., closed Mondays.

The Bird Conservancy of the Rockies has had its headquarters inside the park since 1988 and operates out of the historic Old Stone House Environmental Learning Center on the northwest shore.

The conservancy brings in thousands of visitors each year for lectures, bird banding demonstrations, field trips, and hands-on programs.

The park has all-terrain wheelchairs you can borrow

If walking the trails is a challenge, Barr Lake has a free Track Chair Program with all-terrain wheelchairs built for uneven ground.

The Friends of Barr Lake, a local nonprofit, raised the money to buy two of them for the park. Each outing runs about two to three hours and comes with a trained volunteer.

The park also has ADA-accessible fishing piers, accessible restrooms, and an accessible Nature Center. To reserve a track chair, contact the park directly before your visit.

Hunting, picnics, and dogs on the north end

Waterfowl hunting runs on Wednesdays and Saturdays from October through mid-February, limited to designated blinds north of the dam. Registration with the park office is required before you go out.

Picnic tables are scattered through the park on a first-come basis, and the Meadowlark Pavilion can be reserved for larger group events.

Dogs are welcome on a leash of six feet or less, but they can’t go into the wildlife refuge. Keep that in mind if you’re planning a longer loop with a dog in tow.

A few things to sort out before you go

Getting into the park requires a Colorado State Parks pass, and an annual pass covers every state park in Colorado.

There’s no camping at Barr Lake, but St. Vrain, Cherry Creek, and Chatfield state parks are all nearby if you want to stay the night somewhere.

Pack your own food and water since there are no food services inside the park. The archery range is closed for renovations with no reopening date set.

Water levels change through the season, so check current boating conditions before you plan a day on the lake.
