Comfortable (70–80°F) · Ideal swimming temperature
No active telemetry gauge is currently mapped to Union Lake. Not available from a verified source for this lake.
Historical daily time series not currently recorded for this monitoring station. Real-time continuous digital USGS sensors are prioritized for major floodway rivers.
Tributary runoff, precipitation, and snowmelt elevate the waterbody to its annual summer recreation pool.
Water levels remain stable for peak boating, public park ramps, sport angling, and shoreline swimming.
Regulated seasonal drawdowns or natural seasonal minimums occur to prepare for winter freeze-up and spring capacity.
No recent observation table entries recorded for this site. In-situ stage height is verified through annual bathymetric surveys and state environmental monitoring rather than continuous automated gauge feeds.
Direct in-situ sensor data is required to compute numeric suitability.
Water temperature is not available from a verified source for this lake. No swimming score is shown without it.
