Verified gage-height and water-temperature observations are not currently available for Butt Valley Reservoir in California. LakeRadar does not substitute modeled values.
Maintained within seasonal operating thresholds
Water levels managed within seasonal conservation thresholds
Verified freshwater recreation waterbody
Water temperature is not available from a verified source for this lake. LakeRadar does not estimate it from latitude, season, or a different lake.
No active telemetry gauge is currently mapped to Butt Valley Reservoir. 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.
Estimated from recent weather conditions. Deeper water may be considerably cooler, especially in stratified lakes.
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.
Continuous In-Situ Telemetry Notice: Active continuous automated telemetry stations are not currently installed directly within Butt Valley Reservoir. 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 California Department of Energy & Environmental Protection.
