The Oregon Department of Fish and Wildlife has curtailed
fishing hours on most of Oregon’s rivers to avoid additional stress on native
fish already suffering from high water temperatures and low stream flows from
this year’s drought.
One example of that stress -- an estimated 109 wild spring
chinook salmon in the upper section of the Middle Fork John Day River died last
week, apparently due to low river flows and warm temperatures.
According to Brent Smith, ODFW fish biologist in John Day,
water temperatures in the mid-70s combined with low stream flows likely led to
the deaths of these fish. Like many
rivers across Oregon, stream flows in the Middle Fork John Day have been
extremely low this summer.
The spring chinook die-off was first discovered by ODFW
staff on July 7 near Windlass Creek. The
following two days more dead fish were observed during a survey conducted over
a 17-mile reach downstream of Hwy. 7.
Similar salmon die-offs occurred in 2007 and 2013 with high
temperatures being the main cause.
The Middle Fork’s lack of riparian vegetation combined with
a wide and shallow channel exposes much of the river to direct sunlight which
can lead to cause quick rises in water temperature.
Smith said he expects to see additional salmon mortalities
for the rest of the summer until spawning occurs in early September. He said
the John Day basin as a whole is seeing a strong salmon return this year and
recent summer rains have brought some relief.
Effective Saturday, July 18, and until further notice, all
waterbodies defined as streams in the 2015 Oregon Sportfishing Regulations are
closed above tidewater (where applicable) to fishing for trout salmon,
steelhead and sturgeon from 2 p.m. to one hour before sunrise.
Angling for these species will be prohibited at all times in
the Willamette River downstream of Willamette Falls, including the Clackamas
River up to the Interstate 205 Bridge, the Multnomah Channel and the Gilbert
River. The following sections of the John Day River will also have complete
closures: The mainstem of the John Day
River above Indian Creek near Prairie City; the Middle Fork of the John Day
River above Mosquito Creek near the town of Galena; the North Fork of the John
Day River above Desolation Creek and Desolation Creek.
Normal fishing hours remain in effect for the mainstem
Columbia and Snake rivers.
Some streams will remain open for angling under normal hours
because they are less prone to high water temperature risks due to springs,
tides, cold water releases from some dams and high elevations.
Streams that will remain open for angling under normal hours
-- The Wallowa River
above Sunrise Road; Lostine River above Pole Bridge Campground; Prairie Creek;
Hurricane Creek; Spring Creek; and all streams within the Eagle Cap Wilderness
-- The Malheur River
and its tributaries; the Owyhee River below the Owyhee Reservoir; and the
Blitzen River and its tributaries above Page Springs Weir and Bridge Creek.
-- The Klamath River and its tributaries.
-- The Deschutes
River above Macks Canyon; the Metolius River; the Fall River; the Crooked River
(from mouth to Bowman Dam); and Tumalo Creek.
-- The Hood River and its tributaries and the White River
and its tributaries.
-- The McKenzie River and its tributaries; the Middle Fork
of the Willamette River below Dexter Dam; the Middle Fork of the Willamette
River and its tributaries above Lookout Point Reservoir; and Alton Baker Canoe
-- The mainstem of the South Santiam River below Foster Dam;
Quartzville Creek; the North Santiam River above Detroit Lake; and the
-- The mainstem Rogue River from Fishers Ferry upstream to
William Jess Dam and all tributaries upstream of the William Jess Dam and Lost
“Earlier this month, we indicated that if these drought
conditions continued, we may have to close or restrict some fisheries,” said
Mike Gauvin, ODFW’s recreation fisheries manager. “These are difficult, but
necessary actions to protect native fish already suffering from extreme drought
“This doesn’t mean that all fishing has to stop.” According
to Gauvin, most streams will still be open in the early hours when water
temperatures are cool, and there are many great fishing opportunities in lakes,
reservoirs for hatchery stocked rainbow trout, warmwater fish like, smallmouth
bass or crappie, as well as all of the ocean fisheries.
“As extreme weather events become more frequent due to
climate change, we need to be prepared for the stress these conditions will have
on fish, wildlife and their habitats,” Ed Bowles, Fish Division Administrator
said. “Planning for the effects of these changing climatic conditions presents
a unique challenge for us, yet we are committed to doing our best to enhance
resiliency to climate change and avoid significant impacts on our natural
ODFW already implemented emergency regulations on several
other rivers. In addition, trout stocking schedules and locations have been
adjusted and some hatchery fish have been released early as a result of high
water temperatures. Elevated water temperatures have led to salmon, steelhead,
and sturgeon deaths in several rivers.
Gauvin encourages the public to report sightings of stranded
fish, or other wildlife distressed by drought, to the department and to take
precautions when fishing during these drought conditions.
On days when temperatures soar, anglers can do their part to
reduce the stress on fish by adopting the following measures:
-- Fish early in day when water temperatures are cooler.
-- Use a thermometer to check water temperatures frequently.
Stop fishing when temperatures exceed 70 degrees.
-- Consider changing locations to high elevation lakes or
shaded streams near headwaters. These places are often cooler.
-- Use barbless hooks so you can release fish easily without
-- Use the appropriate gear and land fish quickly. The
longer the fight, the less likely the fish will survive.
-- Keep the fish in the water when you unhook it and cradle
the fish upright until it revives enough to swim away.
-- Use your judgement. If conditions where you want to fish
seem especially severe (low, hot water), consider fishing somewhere else where
water conditions are better.
-- Check the regulation update pages on the ODFW website
before you head out to make sure temporary emergency regulations have not been
put in place for the waters you want to fish.
Gauvin recommends anglers check the weekly Recreation Report
on the ODFW website for updates on stocking, water conditions and boating
In addition to fish and fishing related actions, the dry,
warm weather could increase the danger of wildfires. Wildland fires can destroy
hundreds, sometimes thousands, of acres of habitat. Late season fires may also
affect hunting season dates, hunting opportunities and the condition of winter
range for deer, elk and other species. Fewer water holes means wildlife will
have to travel farther for water. Leave wildlife access to water by not camping
at water sources.
Less water will also increase competition for placement of
hunting blinds amongst hunters. Setting up a blind at a water hole is a common
and lawful practice but hunters are asked to be extra considerate of other
hunters and wildlife this year. Also, follow land manager’s regulations and
don’t set up blinds too early or leave them indefinitely. BLM allows hunting
blinds to be up for 10 days. U.S. Forest Service requires a permit and also has
a time limitation.
The Bureau of Land Management does not allow camping within
300 feet of water sources; U.S. Forest Service rules vary by forest and area.
