Trinity Lake Report
1/19/20 - The lake is now back up over 2,338', down 32' from the spillway, 80% full,
116% of average for the date. We have not seen the lake this full at New Year since 2011.
Due to a wet winter and spring in 2018-19, and a serendipitous failure of an output valve
in the dam last spring, the lake is in amazing shape as we head into winter! The percent
of average number is slipping because the lake is high, but the inflows are below normal.
The last time the lake was about 2,338' on this date was in 2005, and the time before that was 1998.
Last year the lake peaked on June 4, 2019 at 2,367'.
However, the lake may be challenged to stay high again this coming summer due to the lack of precipitation last fall.
And the forecast so far is for a drier winter, though December was a bit above normal.
Here is a graph
of historic lake elevation (updated 12/28) showing spillway and Trinity Center ramp elevations.
(The gaps in the line on the graph are due to missing or bad data in the state's database.)
