Located in Larimer County, Colorado, Sprague Lake is a lake at about 2,648 m (8,688 ft) above sea level. It lies in or next to Rocky Mountain National Park, so park hours, fees and rules apply. It sits roughly 9.5 km (5.9 mi) SW of Estes Park.
Sprague Lake is a scenic lake in Rocky Mountain National Park, located on the south side of Glacier Creek, about two miles south of the Hollowell turnoff. The half-mile walk around the lake is wheelchair accessible and features boardwalks and bridges with views of Flattop Mountain and Hallet Peak. The lake is popular for Brook trout fishing. The area is named after Abner E. Sprague, who started a homestead there in 1874. Later, he opened a lodge for dude ranching, hunting, and fishing. To improve the fishing, he dammed the far end of the lake. The area became part of Rocky Mountain National Park in 1915 and continued to serve guests as the Sprague Hotel. In 1919, guests paid $6.00 per room with a private bath, and $1.00 for regular meals. The hotel, which no longer exists, stood near the present-day parking lot.From the Wikipedia article “Sprague Lake (Colorado)”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Lakes reflect best in calm air — usually the first hour after sunrise, before breezes ripple the surface.

Local time (America/Denver), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Sprague Lake, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.8 hours on a moonless night), and the core peaks around 21° above the southern horizon. Our light-pollution model puts the sky at about Bortle 4 (rural / suburban transition), good enough for detailed Milky Way images.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 4 Bortle 4 — Rural / suburban transition. Light domes are visible in several directions; the Milky Way is clear but lacks detail near the horizon. Modeled zenith brightness ≈ 21.18 mag/arcsec². Aurora needs roughly Kp 7.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 46% average cloud cover) and May as the cloudiest (67%). July is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this lake
- After sunset, long exposures smooth wind ripples into glass.
- For mirror reflections, get low and close to the water; the reflection grows with a lower camera.
- A polarizer can remove reflections to show the lakebed — or keep them, depending on rotation.
- Mist often lifts off lakes on cold mornings after warm days, especially in autumn.
- Include shoreline rocks, reeds or a log as foreground to give the reflection depth.
- Tell someone where you're going in remote areas and carry the ten essentials.
Season: Autumn mornings bring mist and fall color; high-elevation lakes are usually ice-free only from early summer to mid-autumn.
Suggested gear: Tripod, Circular polarizer, Wide-angle lens, Waterproof boots. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
National Park Service rules. Under federal law (54 U.S.C. 100905), still photography in National Park Service areas needs a permit only when it (1) takes place where members of the public are not allowed, (2) uses models, sets or props that are not part of the location's natural or cultural resources or administrative facilities, or (3) would cause the park to incur additional administrative costs to monitor the activity. Ordinary visitor and most landscape photography needs no permit. Commercial filming rules are separate and have changed in recent years — confirm current requirements with the park before a paid shoot.
Drones: Launching, landing or operating unmanned aircraft (drones) is prohibited in National Park Service units under a 2014 Superintendent's closure (36 CFR 1.5), except where a park has issued specific written approval. Flying from outside the boundary over park land can also violate park rules and disturb wildlife.
