Oregon DFW Airlifts Trout to 500 High Lakes

SALEM, Ore. – The Oregon Department of Fish and Wildlife took to the air last week to release 345,000 trout in approximately 500 lakes throughout the Cascade mountain range.
Rainbow, brook and cutthroat trout ranging from 1 to 2 inches in length were trucked from five ODFW hatcheries to heliports at Mt. Hood, Hoodoo Ski Area, Fall River Hatchery, and Klamath Falls so they could be airlifted to some of the state’s most spectacular fishing destinations.
“There is a lot of interest in fishing Oregon’s high mountain lakes, especially this time of year,” said Rhine Messmer, ODFW Recreational Fisheries Program Manager for Inland Fisheries. “It can be really good fishing. The thing about Oregon’s high lakes is there are not a lot of places in the lower 48 United States where you can have this kind of wilderness fishing experience.”
The trout are transported by helicopter in a custom made shuttle carrying 30 individual canisters that hold a couple gallons of water and up to 1,000 fingerlings apiece. The canisters can be opened individually by remote control while the chopper is hovering over a lake. Biologists like to use the smaller, juvenile fish because they can make the 50-100 ft. fall to the lake with less trauma than larger fish, which improves survival rates.
Data collected afterwards in ODFW sampling surveys have shown that once in their new environs the trout are able to establish themselves and grow to harvestable sizes, mostly in the 8- to 12-inch range, but some lakes do produce trout up to or larger than 15 inches.
“It can be very rewarding after a long hike to catch some nice trout and be able to cook them up for dinner or breakfast right out of the lake,” Messmer said.
High lakes fish stocking is nothing new in Oregon. ODFW has been releasing trout in the high lakes for decades. What is new is technology that is making aerial stocking more efficient. Biologists for each participating watershed district plot the flight paths and release sites on handheld GPS units, which they then use to help the helicopter pilot navigate directly to each lake with pinpoint accuracy.
High lakes fishing is very popular according to a survey of anglers conducted by ODFW in 2006. Of those anglers surveyed, 25 percent identified Oregon’s high lakes as their preferred place to fish for trout. That equates to roughly 52,000 anglers per year, according to Messmer.
“It can be a really good fishing experience,” he said. “The crowds are usually smaller, you don’t have competing activities like boats and jet skis, and it’s generally more relaxing, not to mention some exceptional scenery.”
ODFW is currently developing a database of high lakes fisheries, which the department plans to post on its website. In the meantime, anglers are encouraged to consult with local district fish biologists for information about specific lakes.

Just read your post, Is it a cause for concern when there is a restock of 7 fish per estimated visitor.If you include juvenile recruitment(if such exists)Natural predation.That still presents a question about such intensive stocking.
Just posing this question as I am fully in favour of natural recruitment perhaps aided by limited local stripping.What is your view on this as it is a worldwide salmonid problem.

Hi loughcorrib, The restocking program is a way to enhance the high lake fisheries, many people don't keep any of the fish but release them. I would believe that the actual amount that survives to catchable size is relatively small taking into consideration the shock from stocking, predation etc. The stocking program takes into many considerations to achieve the goal of having a sustainable fisheries for these high lakes. This is not a one time stocking but something that takes place every year or two to sustain these levels. Without them, those that hike in and would like to enjoy such a fisheries would more than likely be out of luck. I don't believe the the natural reproduction rate would sustain a fisheries even if these lakes were strictly catch and release due to the mortality rate of released fish and coupled with the slow natural reproduction rate. Also,some of these lakes have virtually no natural reproduction and are virtually sterile without enhanced stocking. The amount of fish planted in individual lakes also take into consideration how much traffic a particular lake will usually get thru the summer and so some lakes will get more fish than others. I applaud the ODFW for their efforts and management of the taxes and dollars from our license fees to enhance this fisheries.
