Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 60°F (15°C) to 65°F (18°C). The water is comfortable for most people, making it an ideal range for water sports enthusiasts. The temperature does not cause significant discomfort, and swimming will be pleasant for the majority. However, it's important to remember that prolonged exposure to the water can still lead to cooling, so it's essential to monitor the time spent in the water, especially for children or elderly people. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

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
Hauser Lake’s surface water temperatures vary substantially through the year. In spring (April–June) the lake commonly runs about 40–60°F (4–16°C) as runoff and cooler air keep temperatures low. By midsummer (July–August) the shallow bays and surface water often warm into the mid‑60s to mid‑70s°F (about 18–24°C), although deeper water remains noticeably colder. In early fall the surface cools back toward roughly 50–65°F (10–18°C), and in winter the lake can approach freezing with typical values near 33–40°F (0.5–4°C) and intermittent ice in sheltered areas. These are approximate surface ranges; depth, weather and inflows can change conditions locally and quickly.
Swimming is generally permitted at Hauser Lake because it is a public recreational reservoir, and people commonly swim from beaches and boat launches in summer when surface temperatures are most comfortable. However, swimmers should be aware that even in warm months the water can feel brisk, cold‑water shock is possible, and boat traffic and currents near the dam or inlets create hazards. Water‑quality issues such as algal blooms or bacterial advisories can occur in warm weather, so checking current local health advisories and using common safety practices (life jackets for weaker swimmers, avoiding deep or fast‑moving water) is wise before entering.
