Clear Lake — a lake in Cerro Gordo County, Iowa at about 373 m (1,224 ft) above sea level — is a rewarding subject for landscape photographers. It sits roughly 3.9 km (2.4 mi) WSW of Clear Lake.
Clear Lake is a natural spring fed body of water located in Cerro Gordo County, Iowa, near Clear Lake, Iowa. It is approximately 3,684 acres (15 km2) in size. It is a popular fishing destination, with walleye, yellow bass and channel catfish. People from Des Moines and Minneapolis–Saint Paul have had homes on the shores of the lake since the 1870s. The average depth is 10 feet (3 m) and the maximum depth is 30 feet (9 m), in the dredged area of the west end. The lake has 13.6 mi (22 km) of shoreline. As of 2004, the lake has seen major efforts undergone to restore its natural clarity, including filtration systems, dredging, and education of local farmers to reduce toxic pesticides from entering the lake. Clear Lake has been named the "Best Iowa Lake Town" by The Des Moines Register and "A Top Vacation Spot" by Midwest Living magazine.From the Wikipedia article “Clear Lake (Iowa)”, 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.

Milky Way & night sky
From Clear Lake, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 3.8 hours on a moonless night), and the core peaks around 18° 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 ≈ 20.54 mag/arcsec². Aurora needs roughly Kp 5.5+ 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 December as the cloudiest (68%). July is the warmest month and January 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.
