Trinity Lake Report
5/24/13 - The lake has slipped below 2,344' and is falling faster now. Lake elevation is down 6 feet
from its peak this month, and down 26+' from the spillway. With the snow essentially gone, the lake is dropping
due to the water going down the river for the fish restoration project (that in over ten years has shown zero progress.)
2013 Trinity Basin Water Year Determination
It shouldn't be a surprise to anyone
that it has been determined that the April 1 water-year forecast for the Trinity watershed is "Dry."
The determination was made by the Calif Dept of Water Resource and National Weather Service.
The forecast is for 823TAF (thousand acre feet) of Trinity Basin inflow putting this year squarely
in the middle of the Dry 650-1025TAF range.
Three flow alternatives were presented to the Trinity Management Council (TMC) for the "shape"
of the 453TAF volume that is allowed to be release into the Trinity River between April and October. The shape of the
flow does not change the total release volume.
After much deliberation, the TMC selected Alternative 3. The exact release days
and times will be determined by the USBR Central Valley Project Operations team.
The river flows began on April 21 and included an 8-day, 2,000 cfs bench (April 23--May 1)
on the ascending limb, followed by a 2-day peak release of 4,500 cfs on May 2-3
The descending limb includes three benches designed for monitoring purposes.
The 8-day bench hopes to improve juvenile rearing habitat in April and May. The low maximum
of 4,500 cfs should help preserve the lake level for tourism this summer.
There are two other Trinity Lake releases this year to watch. First is the biennial "Hoopa
Boat Dance" release around Labor Day weekend (what did they do before the dam??), and the second is a
proposed "Supplemental Fall Release" (similar to 2012) that TLRA opposes due to lack of scientific-need
data. Last year's "Supplemental Fall Release" had no measurable effect.
If you would like to read all of the science data and discussion about this water year and flow alternatives,

from April 10, 2013.
TRLA has a voting seat on the Trinity River advisory committee, know as the Trinity River Adaptive
Management Working Group (TAMWG) and attends TMC meetings.
Google Knows Trinity Center and Coffee Creek!
After about a year of emails with the Google Maps Team it looks like Google Maps
now knows about our North Lake communities.
Now when you search for Trinity Center, you are not taken to the east side of Trinity Lake. They
also know where Coffee Creek is. They don't quite have our street address correct, but neither do most services.
