1.160 2024-03-17Regarding the December 7th measurement, I took that, and have the photo to verify the level. Castle lake is a much smaller catch basin and responds faster to changes.

3.180 2023-12-06This reading is near the time of the maximum lake level recorded at nearby Castle Lake (see USGS gage 14240446), and from inspection of wash lines along the banks of inflowing SF Coldwater Creek and outflowing Coldwater Creek, appears to have been after peak streamflow. So, it is interesting to note that the reading on Dec. 7 is higher. Perhaps this reflects continued increasing outflow from the Spirit Lake drain tunnel? Spirit Lake peaks are significantly delayed compared to unregulated Castle Lake, so probably affects timing of Coldwater Lake peaks. (It's also conceivable the 12-7 reading was in error, or that some debris lodged on the exit channel control.)

2.980 2023-05-16Lots of snowmelt, as well as landslide debris making it to the lake. It’s very high right now. I’d call it close to bankfull.

1.800 2021-04-22Staff plate looks good. No rain and warm weather make the rise from 4/15 entirely due to snowmelt. Similar rises at nearby monitored Spirt Lake and Castle Lake show the same snowmelt rise.
