Verified gage-height and water-temperature observations are not currently available for Ennis Lake in Montana. LakeRadar does not substitute modeled values.
Maintained within seasonal operating thresholds
Water levels managed within seasonal conservation thresholds
Verified freshwater recreation waterbody
Brisk (50–60°F) · Cold shock risk · Wetsuit recommended
No active telemetry gauge is currently mapped to Ennis Lake. Not available from a verified source for this lake.
Nearby river temperature: 58.3°F at Madison River bl Ennis Lake nr McAllister MT (2.2 mi away) · Oct 9, 7:00 AM UTC
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.
Current index calculated from verified local atmospheric, hydrographic & alert inputs.
Poor for swimming (48/100), from 5 available inputs. Supporting this: No active official alerts for this lake. 0% chance of precipitation. Working against it: Measured water temperature 58°F from a representative gauge 2.2 mi away. Provisional data. Cold water hazard: thermal protection recommended below 60°F. Air temperature 56°F. Water temperature is 58°F (below 60°F). Immersion requires thermal protection. Confidence is moderate (83%) because some inputs are unavailable or older than ideal.
Continuous In-Situ Telemetry Notice: Active continuous automated telemetry stations are not currently installed directly within Ennis Lake. Not available from a verified source for this lake.
Official vertical datum, navigational perimeter geometry, and bathymetric basin contours are cataloged from official hydrographic surveys conducted by Montana Department of Energy & Environmental Protection.
