Best Fishing Times for Upper Estuary Lake
14-day solunar fishing calendar for Upper Estuary Lake, St. Louis County, Minnesota — sun and moon times calculated for lat 46.658, lon -92.243.
On the scoring rubric Upper Estuary Lake grades a D: clarity at 1.9 ft and 49 µg/L of phosphorus keep it in the lower bracket for St. Louis County. Clarity is the limiting factor — phosphorus is reasonable but suspended particles or algal cells keep water transparency below Minnesota norms.
A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. Upper Estuary Lake is unusually deep for Minnesota at 55 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. At 10,255 acres, Upper Estuary Lake is one of the larger lakes in St. Louis County, with 195.5 miles of shoreline supporting multiple distinct use patterns. Within the 215 graded lakes of St. Louis County, Upper Estuary Lake sits at rank 200, near the bottom of the county list.

How to Read This Calendar
Major periods (≈2 hours) are centered on lunar transit (when the moon is highest in the sky) and lunar opposition (when the moon is directly underfoot). These are typically the strongest feeding windows.
Minor periods (≈1 hour) are centered on moonrise and moonset. They're secondary windows that often produce well — especially when they coincide with sunrise or sunset.
Day rating combines moon phase (peak near new and full moons, when lunar gravity is strongest) with the overlap of major periods and the dawn/dusk twilight. A 4–5 star day stacks all three.
At Upper Estuary Lake (lat 46.66°N), the longest day of the year is around June 21 with 15h 51m of daylight. The shortest is around December 21 with 8h 33m. Plan summer trips around the early-morning bite (as early as 5:00 AM) and the long evening window before sunset.
Frequently Asked Questions
What is the best time to fish Upper Estuary Lake today?
Today's solunar calendar for Upper Estuary Lake (lat 46.66, lon -92.24) shows sunrise at 5:22 AM and sunset at 9:04 PM. The strongest fishing windows are around major solunar periods at 4:59 AM–6:59 AM and 5:21 PM–7:21 PM, plus the 30-90 minutes around dawn and dusk.
What does the moon phase mean for fishing Upper Estuary Lake?
Solunar theory holds that fish activity peaks during major periods (when the moon is overhead or directly underfoot) and minor periods (moonrise and moonset). Fish feeding tends to intensify during the days surrounding the new moon and full moon, when lunar gravity is strongest. Today's moon at Upper Estuary Lake is Last Quarter (58% illuminated).
When are the longest and shortest days at Upper Estuary Lake?
At Upper Estuary Lake's latitude (46.66°N), the longest day of the year is around June 21 with about 15h 51m of daylight. The shortest day is around December 21 with about 8h 33m of daylight. Sunrise and sunset shift by roughly 6 hours between solstices.
Are major or minor solunar periods more important?
Major periods (about 2 hours, centered on lunar transit and lunar opposition) are generally considered the strongest feeding windows. Minor periods (about 1 hour, centered on moonrise and moonset) are secondary but still productive — especially when they overlap with sunrise or sunset.
