Aurora Reservoir - Arapahoe County
Ownership: None Listed
Description: (submitted by Glenn Walbek) Aurora Reservoir in Arapahoe County is one of a few Front Range reservoirs surrounded by prairie grassland. It sits about 9 miles east of Cherry Creek Reservoir, well away from the urban sights and sounds of Denver. This slight distance makes Aurora Reservoir a reliable site for Snow and Ross's Geese, birds that can be difficult to encounter closer to town. Aurora Reservoir can host a good variety of water birds in the fall and winter, including the usual divers, swans, loons and even scoters. Shoreline is not expansive but can attract migrant shorebirds, with the south shore being best. Gulls and terns are varied and reliable, with many birds sharing time with nearby Quincy and Cherry Creek reservoirs. The park does not hold many trees so passerines are not abundant, but grassland sparrows and raptors add to the good numbers of water birds, making Aurora Reservoir worth a visit.

Aurora Reservoir is not part of the State Park System, so your annual Parks Pass will do you no good here. The city of Aurora charges $10 for a day pass and $55 for an annual pass.

Habitat: Reservoir, Lowland Riparian, Grassland/Prairie
Directions: Take E-470 to the Quincy Ave exit (or, alternatively for those who don't want to pay tolls on E-470, take I-225 to Parker Rd, and then Parker Rd south to Quincy Ave). Head east on Quincy Ave for 2 miles to Powhaton Rd, and the entrance to Aurora Reservoir, on the right.
