Green River and not a single angler reported
harvesting a trout, despite catching and
releasing hundreds of fish, " Rhea said.
The portion of the river sampled near
Big Piney smashed historic records. Trout
numbers were estimated at 560 per mile.
" We have seen estimates of trout numbers
higher in this reach, but we have never seen
a biomass estimate anywhere near what we
recorded in 2020, " Rhea said.
Biomass estimates account for the total
pounds of fish in the water. Despite similar
numbers of fish in the river compared to
previous years, the trout population is made

Despite the current circumstances and
short-term prospects of the fishery, Rhea
said he is encouraged by the outcome from
the 2020 sampling effort.
" Overall it indicates the river is healthy
and resilient to annual changes in climate
and flow, " he said. " For close to 20 years, I
have witnessed the ups and downs in the river
fishery as a result of dry and wet periods, but
if we continue to care for our water and land
and make the best use of our resources, I am
certain the Green River fishery will persist
for many generations to enjoy. "

up of much larger individuals than past years.
By all accounts, 2020 may have been the
" glory days " of fishing on the Green River.
Unfortunately, Rhea doesn't expect that to
persist. Continued drought conditions and
low flows do not bode well for future fish
populations. Lower than average discharge
means less winter habitat and reduced survival for many fish in the river.
" I suspect we will see a drop in overall
fish numbers in 2021, and without significant snowfall during the winter, we may see
dramatic impacts that will last for a period
of years, " Rhea said.
