Water and conditions
Our water temperature readings average 72°F; they do not cover the whole year, so this is not a yearly average. pH averages 8.3. These readings span 2019–2020. The latest reading is from 2020, more than three years ago: read these numbers as history, not as the water today.
Where this data comes from
- US Bureau of Reclamation — USBR reservoir sedimentation surveys: class A, a survey of the bottom, 2004.
Part of these depths rest on an averaged water level, so they are approximate (≈).
