*** Forecast - Our water temperature forecast

Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.

Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information

Snakeden Hollow’s lakes are former strip‑mine pits, so their water temperatures vary widely by season, depth, and local weather. Surface readings in spring commonly range from about 40–65°F (4–18°C) as waters warm after ice melt, while midsummer surface temperatures often reach roughly 65–80°F (18–27°C) in shallower basins. In contrast, deeper holes can remain cool even in summer, frequently holding water in the 40–50°F (4–10°C) range below the thermocline. During autumn the surface generally cools back toward 40–65°F (4–18°C), and in winter lakes may ice over with near‑freezing conditions around 32°F (0°C) where ice forms.

Swimming at Snakeden Hollow is not promoted because there are no developed public swimming beaches or lifeguarded facilities, and management emphasis is on fishing and wildlife habitat. The former‑mining topography produces steep drop‑offs, submerged rubble and brush, and cold deep water that can create dangerous conditions for casual swimmers, including risk of hypothermia and entrapment. For those considering water recreation, canoeing or fishing from boats is common, but direct contact with the water should be approached cautiously and only after confirming site‑specific rules and safety provisions.
