Water Temperature: Daily Trends, Historical Records, and Forecast
✅ As of today, the minimum water temperature is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating. 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.

*** 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
Waconda Lake (Glen Elder Reservoir) experiences marked seasonal variation in surface water temperature. In spring the surface typically rises from roughly 45–65°F (7–18°C) as inflows and air temperatures warm. Summer surface temperatures commonly reach about 70–85°F (21–29°C) on warm afternoons, though deeper water remains cooler. During autumn the lake cools back toward roughly 50–70°F (10–21°C) depending on early or late fall conditions. In winter the surface often approaches near-freezing to the low 40s, roughly 32–45°F (0–7°C), especially when cold air and ice formation occur in sheltered areas. Water temperature can vary locally with depth, wind, and reservoir releases, so swimmers should expect cooler pockets even in summer.
Swimming is permitted in recreational areas around the lake, particularly at park-managed shorelines, because the reservoir is designated for multiple public uses including bathing and boating. However, access and safety depend on conditions: there are often no lifeguards on duty, water levels and submerged hazards can shift with reservoir operations, and occasional algal or water-quality advisories may limit swimming. For those planning to swim, summertime afternoons offer the warmest surface temperatures, but checking current park notices and exercising caution around variable depths and cold pockets is recommended.
