Best Fishing Times for Silver Island Lake
14-day solunar fishing calendar for Silver Island Lake, Lake County, Minnesota — sun and moon times calculated for lat 47.734, lon -91.140.
Silver Island Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.
Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. Silver Island Lake reaches 16 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 1,239 acres, Silver Island Lake is one of the larger lakes in Lake County, with 16.9 miles of shoreline supporting multiple distinct use patterns. Silver Island Lake ranks 130 of 159 in Lake County — at the lower end of the locally monitored distribution.

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 Silver Island Lake (lat 47.73°N), the longest day of the year is around June 21 with 16h 0m of daylight. The shortest is around December 21 with 8h 24m. 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 Silver Island Lake today?
Today's solunar calendar for Silver Island Lake (lat 47.73, lon -91.14) shows sunrise at 5:13 AM and sunset at 9:04 PM. The strongest fishing windows are around major solunar periods at 4:55 AM–6:55 AM and 5:17 PM–7:17 PM, plus the 30-90 minutes around dawn and dusk.
What does the moon phase mean for fishing Silver Island 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 Silver Island Lake is Last Quarter (58% illuminated).
When are the longest and shortest days at Silver Island Lake?
At Silver Island Lake's latitude (47.73°N), the longest day of the year is around June 21 with about 16h 0m of daylight. The shortest day is around December 21 with about 8h 24m 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.
