Some 102,000 spring Chinook salmon smolts destined for the Imnaha River by way of a tanker truck unsuccessful to reach their destination on March 29 when the tanker crashed future to Lookingglass Creek in close proximity to the Lookingglass Hatchery in northeastern Oregon, the Oregon Section of Fish and Wildlife reviews. The spot of the crash was, in a way, serendipitous. Pretty much 75 p.c of the smolts landed in the creek, which is a tributary of the Grande Ronde River. Another 26,000 died in the incident.
An ODFW employee was driving the 53-foot truck when it rolled onto the passenger aspect following heading all-around a tight curve in the road. The Union County Sheriff’s department responded to the incident, during which the driver received small accidents. Responders have been also capable to have small quantities of diesel fuel from moving into the waterway.
Both of those the Grande Ronde and Imnaha Rivers are tributaries of the Snake River, which lessens the severity of the misplaced salmon smolts. But when a compact proportion of those people smolts return as grown ups in 2026 and 2027, ODFW biologists assume them to return to Lookingglass Creek rather than the Imnaha. This could lead to between 500 and 900 much less adult chinook coming back to the Imnaha throughout these a long time, in accordance to ODFW. On the vivid facet, the agency expects all over 350 to 700 of the 77,000 smolts spilled into Lookingglass to return to the creek all over the very same time.
The truckload of spilled smolts also represented only about 20 p.c of scheduled hatchery releases on the Imnaha this 12 months, meaning that some 400,000 a lot more Chinook smolts are destined for the very same location. (This determine matches the 2023 hatchery smolt launch intention for the Imnaha, in accordance to the release program’s 2023 once-a-year working approach.)
The Nez Perce Tribe and the Confederated Tribes of the Umatilla Indian Reservation are co-professionals of the fishery. NPT also responded to the scene and assisted ODFW gather, depend, and scan each and every a single of the 26,000 dead fish for “Passive Integrated Transponders.” PITs are microchips that in essence give an person animal a barcode for simplicity of tracking.
“Information collected from PIT tags, together with those that weren’t launched, will support assure the finest probable estimates of survival and long term grownup returns,” the ODFW push release reads.
The Imnaha spring Chinook run is frequently impacted by early fishing closures to secure dwindling wild populations. For illustration, an early closure occurred in the initial 7 days of July 2023. The Imnaha is preferred with anglers, for this reason the intense stocking software to dietary supplement figures. That supplementation strategy has transpired due to the fact 1982 as aspect of the Reduced Snake River Payment Plan system.

All explained to, the incident will not have as well serious of an effects on the general overall health of hatchery Chinook runs in the Decreased Snake.
“We are thankful the ODFW worker driving the truck was not seriously wounded,” reported ODFW’s japanese Oregon fish hatchery coordinator Andrew Gibbs. “This should not effects our capacity to collect future brood inventory or sustain total production objectives in the long run.”
