*** 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
Cagles Mill Lake, also known as the reservoir behind Cataract Dam in west-central Indiana, experiences marked seasonal shifts in surface temperature. In winter the lake often approaches freezing, with surface readings commonly around 32–40°F (0–4°C) and frequent ice formation in shallow bays. Spring brings a steady warming, roughly 40–60°F (4–15°C) as runoff and rising air temperatures heat the upper layers. Peak summer surface temperatures are typically in the 68–80°F range (20–27°C) during July and August, when the water is most comfortable for bathing. During autumn the lake cools again, with surface temperatures generally falling to 50–65°F (10–18°C) depending on air conditions and wind.
Recreational swimming in and around Cagles Mill Lake is generally permitted, but facilities and supervision are limited. The lake is managed by the U.S. Army Corps of Engineers and local authorities, and swimming is often done from shore or private boats rather than at staffed, lifeguarded beaches. Because of changing temperatures, variable depth, underwater hazards, boat traffic and the lack of lifeguards in many areas, swimmers should follow posted regulations, prefer shallow, sheltered spots, wear life jackets when appropriate, and be mindful of cold-water shock in early and late season.
