What's Endangered,
the Snake River or the Truth?

Graphic: With cold water released from the depths of Dworshak Reservoir, the Clearwater River would cool river temperatures if their were no reservoir at the confluence with the Snake River.  Now, with the reservoir, the cool water, heavier than the warm Snake River, mostly slips underneath with very little mixing of the waters. The national interest in the Lower Snake River continues in 2021, with this river being recently identified as the "most endangered river in the United States" by the organization American Rivers.

One of the "contributing issues" is apparently elevated water temperatures, which is commonly attributed to the presence of the Lower Snake River dams.

But an "inconvenient truth" is that the Snake River's waters can be "naturally hot" far upstream of these four dams, as was illustrated in 2015, a recently experienced "hot water year."

Temperature data collected at the U.S. Geological Survey, or USGS, Weiser and Nyssa Gaging Stations easily illustrated this fact, as did data collected at the USGS Clearwater River Orofino Station.

Unfortunately water temperature data collection at the USGS Weiser and Nyssa locations was terminated late in 2015 due to "loss of funding," and the the 2015 Data at the USGS Orofino location is no longer available for viewing on the USGS website.

It appears that when the "real river data" contradicts the agenda at hand, the proper thing to do is quit collecting the offending data and also make the offending historical data previously collected unavailable to the general public.
