I’m always fascinated by how these death flows (450 cfs) are not corrected until a considerable amount of time passes and disease gets out of control before a predictable “emergency” is declared and more flows are released to cool down the Trinity. The irrigation elites down south don’t need a single drop of Trinity water this year, and yet the same people with the power to save fish sit on their hands. That’s a good one to blame thunderstorms a month later, nice creativity there.</div><div dir="ltr"><br></div><div dir="ltr">Just stop sending Trinity water over to the Sacramento. They don’t need it! Increase flows from Lewiston to 1000 cfs!

<h2 class="gmail-has-text-align-left">Trinity River: <strong>Current Conditions</strong></h2>
<p>Concerning news of spring chinook infected with an undiagnosed gill
infection have been reported at higher rates than years prior and has
the attention of agencies, anglers and those on the river. Although the
average rates and the location of these reports have been concerning,
some daily rates of reported infections have been alarming and have
definitely garnered the attention of regulatory agencies. The evidence
of disease is somewhat surprising because upper river temperatures are
not exceptionally high. A key differentiating factor hypothesized by
fish biologists, may be that the heavy sediment and ash loads from
thunderstorms in June may have damaged the gills of the spring chinook
that were making their way upriver at that time, stressing them and thus
making them vulnerable to disease.</p>
<p>It is helpful to know that there are several advisory groups that
meet regularly to discuss Trinity & Klamath River conditions. The
KFHAT (Klamath Fish Health Assessment Team) evaluates current conditions
and meets weekly and/or as needed throughout the summer and fall
period. The Klamath Flow Augmentations Releases (FARs) group meets
bi-weekly (or as needed) and are meant to protect migrating salmon in
the summer and fall months, when conditions can become poor in the lower
Klamath River. The flows, water temperature, fish observations, and
disease rates are all monitored using data collected by several
partnering agencies such as the California Department of Fish and
Wildlife (CDFW), Hoopa Valley Tribe and Yurok Tribe to determine if a
FAR recommendation is needed. </p>
<p>Fish can catch disease if they are stressed and there are several
factors that play into this (water quality: including turbidity and
temperature, lamprey predation, being handled or caught, etc.). Experts
are in agreement that water temperatures at Lewiston are good, around 53
F, which is about 3-4 F cooler than last year. Overall, water
temperatures and flows in the upper Trinity River appear suitable for
adults and would not be expected to cause gill lesions alone. </p>
<p>To monitor temperatures, there are currently four locations that
upload to the USGS website located at Lewiston Dam, Douglas City*, North
Fork Trinity River, and in Hoopa. You can view all of these temperature
readings by clicking the corresponding links below. The links will also
show last year’s (2022) temperature readings for contrast. We see river
temps rise this time of year and should start to see them fall slowly
down as day lengths shorten – typically starting in August. </p>

<p>Those involved will continue to discuss any appropriate
recommendations for responses to this issue, should a response be
warranted. They will continue to monitor the situation and meet to
discuss new information in the coming days.</p>
<p><em>*The Douglas City temperature gauge is now functioning. A
replacement from USGS was administered and real time temperature
readings came back on-line the morning of July 18. While the gauge that
uploads to the internet in real time was damaged, data was still being
collected at this site. </em></p></div></div></div></div></div></div></div></div>
