*** 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
Fall River Lake in southeastern Kansas typically follows the seasonal patterns of inland reservoirs: water remains quite cool through spring, warms in summer, and cools again in fall and winter. Typical surface temperatures in spring range roughly 45–65°F (7–18°C) depending on air temperatures and recent rains. In midsummer the shallows and surface waters commonly reach about 70–85°F (21–29°C), with the warmest readings in July and August on calm, sunny days. By autumn the lake usually falls back to approximately 50–70°F (10–21°C), and in winter surface temperatures often sit near freezing up to about 45°F (0–7°C) with colder snaps driving temperatures lower in the water column.
Swimming is generally allowed at Fall River Lake in designated recreation areas and at the state park beach when facilities are open; it is a public recreation reservoir managed for boating, fishing and bathing. There are usually no permanent lifeguards, so swimming is typically at your own risk and subject to seasonal openings, posted warnings, or temporary closures for water quality or safety issues such as algae, high flows, or low visibility. As with any reservoir, temperatures vary with depth and weather, so swimmers should exercise caution, avoid sudden exposure to cold water, and heed local signage and seasonal guidance.
