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.
Good for swimming (84/100), from 5 available inputs. Supporting this: No active official alerts for this lake. Measured water temperature 78°F from a representative gauge 6.8 mi away. Provisional data. Working against it: 79% chance of precipitation is likely. Confidence is high (87%).
Continuous In-Situ Telemetry Notice: Active continuous automated telemetry stations are not currently installed directly within Mountain Island 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 North Carolina Department of Energy & Environmental Protection.
