Greer Lakes wildlife closure protects nesting bald eagles through June 30

River Reservoir in the Greer Lakes area is off-limits through June 30, and that is the detail to check before anyone points a truck toward the White Mountains. Apache-Sitgreaves National Forests put the seasonal wildlife closure in place on May 1 to reduce disturbance to bald eagles during nesting and fledgling season, turning the shoreline and surrounding forestland inside the defined boundary into a temporary no-entry zone.

The order covers National Forest System lands around River Reservoir, not an across-the-board shutdown of the area. Apache County Roads 1126 and 1015 remain open unless otherwise closed, which matters for trip planning because drivers can still pass through the corridor even while the reservoir itself stays protected. The closure also keeps access in place for permit holders, law enforcement, and rescue personnel, standard language for a restriction built around wildlife protection rather than roadwork or a short-term trail fix.

The move is rooted in the Bald and Golden Eagle Protection Act, and Arizona Game and Fish Department has been blunt about why these closures exist. Too much human disturbance can cause a nest to fail, trigger premature fledging, and leave eaglets exposed to injury or death before they can fly or defend themselves. That is the practical consequence behind the boundary line at Greer Lakes: this is about giving a breeding pair space now so the site remains viable later.

The timing fits a broader Arizona management pattern. The Arizona Bald Eagle Nestwatch Program began in 1978 as a weekend volunteer effort by the U.S. Forest Service and Maricopa Audubon Society, and it has grown to about 20 biologists annually. Protection efforts are coordinated through the Southwestern Bald Eagle Management Committee and carried out through the Arizona Game and Fish Department. This work comes at a moment when Arizona’s breeding bald eagle population hit a record 90 adult pairs and 96 young during the 2024 season, a strong reminder that these high-country nesting sites are not expendable.

Greer Lakes has also shown up in earlier seasonal advisories as a place where portions of the lake can close to watercraft and shoreline access can close to foot entry depending on nest location. Arizona’s statewide eagle advisory also includes a 2,000-foot AGL airspace buffer along some drainages and lakes, including Greer Lakes, which adds another layer for pilots and drone users to respect. For anyone building a spring or early-summer run through Apache County, River Reservoir is a place to verify carefully before departure, not assume is open just because the roads still are.
