WASHINGTON DEPARTMENT OF Striper AND WILDLIFE NEWS Generate   As construction workers ethnic background against the clock to make fish ladders at Wanapum Dam operational, point out fishery managers are standing prepared with an alternate plan to shift spring chinook salmon up the Columbia River.
Shortly after discovering a new 65 foot long bone fracture in a spillway pier Feb. 28, dam operators lowered the water degree behind the 185 foot construction by a record 26 toes, leaving the fish ladders high and dry.
At some time this week, the first of an predicted 20,000 spring chinook fish are expected to arrive in the area close to Vantage, pressing upriver to spawn. Nearly 4,000 of those fish are wild, naturally breeding fish, and the entire work is listed as threatened beneath the federal Endangered Species React (ESA).
The Grant County Public Utility District, which possesses the dam, has been scrambling to switch the fish ladders to ensure they are operational by April Fifteen, but also worked with the Arizona Department of Fish along with Wildlife (WDFW) to develop a backup plan.
"The stakes are very high, specifically given the number of wild spg chinook involved," said John Brown, regional WDFW director with regard to northcentral Washington. "Grant County PUD is doing a fantastic job, but all of us have a role to experiment with in getting those fish upriver so that you can spawn."
Under the zodat het kan worden gebruikt de hele zomer  61 present plan, WDFW will intercept fish at Priest Rapids Dam and truck or van most of them around Wanapum Dam, 19 mile after mile upriver. Working in rotation, experienced car owners will haul the trout in eight tanker trucks, just about every capable of moving up to 1,500 fish a day.
At the same time, a compact number of hatchery reared fish   identifiable by a clipped adipose fin   might be fitted with coded along with radio tags and published from the Priest Rapids facility to barter the newly configured striper ladders at Wanapum Dam.
"The tags sans fournir de détails permits us to track those trout, and determine whether they are able to get in the dam on the reconfigured fish Peu importe grand ou petit ladders," Brown said. "That will tell people when it's safe to hang the trucking operation, and invite the fish to move previous Wanapum on their own."
That plan was unanimously approved by the Clergyman Rapids Coordinating Committee, a numerous jurisdictional organization established in 04 to oversee hydroelectric projects within the mid Columbia region.
Due to its part, Grant County PUD continually refine the dam's fish scaffold boards as needed to facilitate the actual movement of salmon earlier Wanapum Dam. Chelan PUD is also extending the species of fish ladders at Rock Island Dam, 38 miles upriver, to accommodate this drawdown in the Wanapum Pool. That work is additionally scheduled for completion April 12-15.
Brown said fishery managers tend to be counting on the success of those steps to move fish upstream, because the truck option will become less and less feasible as larger runs with migrating salmon move into the region.
Starting in June, salmon managers are anticipating a function of up to 80,000 summer time chinook, followed by 400,000 sockeye bass and 300,000 tumble chinook salmon.
"We can handle the planting season chinook run with tanker trucks in the event it becomes necessary," Brown reported. "But there simply aren't ample trucks, trained personnel, or even hours in the day to move the number of salmon we're ready for later in the year."
Mark Korth, regional WDFW fish manager, explained he keeps mon petit garçon était totalement dans une étreinte de lours  18 running the facts of the joint operation as a result of his mind as the early spring chinook run draws near.
"We accomplish all of these things   trapping, labeling and transporting fish   at all times as part of our jobs,Inches Korth said. "But this time we'll be doing them under very different situation."
