Dworshak Fish Hatchery receives Station of the Year Award
You may remember back in
August that the main water line from Dworshak Dam to Clearwater State Fish
Hatchery was damaged (see October
15, 2012 post for details). The water line needed to be shut down in order
to investigate and repair the damage. This left Clearwater Hatchery in short
water supply. In order to save their 2011 brood of Spring Chinook, 2.5 million
fish, Clearwater needed to find some water. Since Dworshak Fish Hatchery is
right across the river from Clearwater Hatchery it was the logical place to
look.

Both hatcheries can share
reservoir water, but most of Dworshak’s water comes from the North Fork
Clearwater River, about a mile below the Dam. The river water comes with its
share of problems- the biggest is IHNV, a virus that can be deadly to
steelhead. This is why Clearwater Hatchery uses disease free reservoir water as
its sole water source. Pumping river water to Clearwater Hatchery was not an
option, but moving their fish to Dworshak was.

Planning and preparing for
the fish move was tough and took a lot of teamwork. With help from the Nez
Perce Tribal Hatchery, the Idaho Department of Fish and Game, the Lower Snake
River Compensation Program, the Environmental Protection Agency, and the Army
Corps of Engineers, we were able to prepare 25 Burrow’s ponds, improve our
waste water system to accommodate the additional fish, modify our drain lines
to handle the additional water use and move 2.5 million juvenile Spring Chinook
from the Clearwater Hatchery to Dworshak in less than two weeks.

Over the winter there has
been a cadre of IDF&G staff at Dworshak taking care of their Chinook and
helping out with a continuous list of projects and daily maintenance. They have
become part of the Dworshak team helping trouble shoot our ever changing
cleaning operations; always willing to lend a hand.
This week the Clearwater Chinook
smolts are being trucked off-station for release as they begin their long
migration downriver to the ocean. Mark Drobish,
Hatchery Manager at Dworshak Fish Hatchery said, “It’s all about rearing
healthy fish at our hatcheries and this effort was truly one of team spirit, quick
action and cooperation between state, federal, and tribal agencies to take a
crisis and turn it into a success story.

The Lower Snake River Compensation Program (LSRCP) recognized
Dworshak Fish Hatchery’s efforts by awarding them the Station of the Year Award.
Without the coordination, cooperation and effort from multiple agencies
Clearwater Hatchery would have lost all those salmon. That not only would have
been tragic for the hatchery, but for the Tribal and sports fishermen that
utilize this resource, and for the countless animals that depend on these fish.
