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
Lake Carl Blackwell’s water temperatures follow the typical seasonal pattern for a midwestern reservoir. Surface temperatures in summer commonly reach the mid‑70s to upper‑80s °F (about 24–31 °C), making the shallows quite warm by July and August. In spring the water warms from roughly 50–70 °F (10–21 °C) as air temperatures rise, while fall sees a cooling trend back into the mid‑50s to mid‑70s °F (13–24 °C). Winter surface temperatures are generally much cooler, often ranging from the mid‑30s to low‑50s °F (2–10 °C). Deeper water remains noticeably colder year‑round, and the lake can stratify in the warm months so that temperatures below the thermocline are lower than surface readings.
Swimming is permitted at Lake Carl Blackwell, and people commonly swim from shorelines and park areas, though facilities do not typically provide lifeguards and conditions can change with weather. Visitors should heed posted advisories because heavy rains, algae blooms, or turbidity can affect water quality and safety. Because of variable temperatures—warm near shore in summer but cool at depth—swimmers should be cautious about sudden exposure to colder water and avoid swimming alone; checking current local conditions before entering the water is recommended.
