Detroit Stocking Update 9-28-2017
This years fingerlings have been planted in Detroit. 27,000 4.5-5″ smolts made their way into the lake. All these are fin clipped. Please continue to report your catches as it will be very important for us to track the progress of this project and the size and quantity of these that survive. Here is a short video of them being let go in the lake.
Kokanee Aging Project
Kokanee Power of Oregon (KPO) is looking for additional funding to support the aging of spawning Kokanee from Wickiup, Odell, and Paulina lakes. The purpose of this project is to determine if there is a difference in age at spawning between Wickiup Kokanee and the other two lakes. Currently all eggs for hatchery programs are collected from Odell and Paulina lakes. They are then reared at Wizard Falls Hatchery and stocked in several other water bodies later in the year (usually June). For the past several years, the fish at Wickiup have been significantly larger than any other lake. This could be the result of warmer water temperatures earlier which produces a longer growth period of zooplankton, or just maybe these Kokanee are spawning one year later than Odell and Paulina?
Kokanee age estimates would be produced under contract by the lab in Corvallis where other fish are aged for ODFW. KPO will share the cost which for all three lakes is approximately $1800 to age 25 fish from each lake. Aging is accomplished by collecting 10 of the largest scales off each fish, then trained technicians prepare and examine them under a micro scope to determine the age of each fish.
Once the aging is completed, and if by chance the Wickiup Kokanee are spawning at four years and the other lakes are spawning at three years, KPO will work with ODFW to collect eggs from the Deschutes Channel at Wickiup to be grown out at Wizard Falls and see if we can get a strain of larger Kokanee stocked in other lakes to increase the average size in the future.
If anyone is interested in donating some funds to accomplish this, please send funds to Oregon Fisheries Enhancement FDN, 782 SE 40th Court, Hillsboro, Oregon 97123, or contact Rick Breckel, Project Coordinator at firstname.lastname@example.org.
The KPO would like to introduce Matt Schindler’s Fly Shack as a new sponsor. Matt’s flies have been very effective at catching kokanee. See some of his flies in the picture below. See Matt’s contact information (971) 344-4543 Schindlersflyshack@gmail.com. Please support our sponsors.
Two more new sponsors we would like to introduce. Frank’s Fly Box and 2 Old Farts Tackle. Both of these tackle suppliers have proven tackle. Frank won the Chelan Kokanee Derby up in Washington with his Kokanee Kandies. Don did real good at the Odell Derby with his tackle.
Mill City Shop Class helps ODFW at Detroit Lake June 13, 2017
A non-profit volunteer group known as Kokanee Power of Oregon (KPO) has been working with ODFW to promote the enhancement of Kokanee fisheries at Detroit Lake for the past four years. The most recent accomplishment was to coordinate the development of detailed signs with attached drop boxes, where anglers can report their daily catch to ODFW. This will greatly assist ODFW in future decisions regarding fish stocking and daily catch limit regulations.
The Mill City Shop class, supervised by their teacher Chris Lindeman built 26 drop boxes last winter for anglers to place their catch records within. Last Tuesday, 18 of the shop class participants came up the Detroit State Park to begin the installation of a total of 14 of these signs located at key fishing locations. This is only one of the many projects that the shop class has accomplished during the year to not only teach the class the art of using tools, but also the benefits to many of the community organizations such as the senior center and others. The community is lucky to have a school district who can see the value of a program such as this.
When anglers are finished for the day, they are all encouraged to fill out one of the cards in the drop box at each sign. Fill it out and put it in the slot on the box. Then KPO representatives will collect them weekly and send to ODFW. This is a long term project that if successful, may be expanded to other lakes. Another way to report catch data is to log in to Kokaneepoweroregon.com and go to fishing reports. It is very quick and simple.
News Update – March 14, 2017
Brad’s Killer Fishing Gear is now an official sponsor of the KPO.
Detroit Reservoir Project Update – January 30, 2017
A correction to the stocking levels starting this year.
ODFW will ONLY be stocking the 25,000 – 30,000 fin marked Kokanee that are raised up to a size of about 5.5″ long, or 20/lb. This way, in a few years, with our monitoring program, we will be able to determine how much natural reproduction is occurring compared to the fish caught that are fin marked. There will be no non-fin clipped kokanee stocked during this project for the next few years.
Detroit Reservoir Project Update – January 9, 2017
Members of KPO met with ODFW biologist Alex Ferrand November 15, 2016 to discuss design of the signs and drop boxes which will be constructed and placed at up to fourteen locations around Detroit Reservoir. KPO members designed a draft of the sign to be posted, and Alex is working specifically with the Information and Education division at ODFW to create the final version and get it printed either on a metal sign or heavy laminated version that will be two to three feet in size and posted on a kiosk like back board sign. Then a simple drop box with catch record cards will be mounted below whereby anglers can fill out the days catch and drop the card into the slot inside the box. One of the members will then collect these cards weekly and take them to ODFW for tabulation and future decisions on stocking both Kokanee and rainbow trout. The Mill City Shop class will be starting on construction of the drop boxes mid January and once both the signs and drop boxes are complete, members of KPO will install them at each location. Coordination with US Forest Service, State Parks, US Army Corps of Engineers, both Marinas, and private camp grounds is ongoing. Our goal is to have all the drop boxes and signs installed by March 1st so that nearly all of the fish caught at the primary locations will be recorded. ODFW has told us that this is the kind of data they need to make adjustments in both the daily limits and annual stocking rates for rainbow trout and Kokanee. Depending on the results we are hoping that the daily limit can be increased and rainbow stocking will be reduced.
An update on the original project that we were planning is that for the next three years the Kokanee we raised at Wizard Falls Hatchery were planned be held over until March of the next year before stocking. Our last discussion with Hatchery Manager Luke Allen indicated that due to pond space availability, it is more likely they will only be held until October like they were this year. That only means that they will be 5.5″ long when planted instead of maybe 8″ due to slower growth rates during winter months. If results show that the 5.5″ fish are able to escape predation sufficiently, then we’ll save on food for them during winter months. Bio-Oregon recently announced that they will again donate all the fish food for the Kokanee that are raised to a larger size and stocked into Detroit. This can be a value of up to $2500. We sincerely appreciate their help!
This last year, in June, 75,000 fingerlings were stocked by ODFW. Then in October, the other 25,000 clipped fish (5.5″ long) were stocked. This concept will continue for the next 3-4 years unless results indicate a change to this plan is beneficial.
Update on the Detroit Reservoir Project
This years kokanee fry were successfully released into Detroit on Monday 10/3 and Tues 10/4. The fry were raised to 5.5″ and were in good health. There was no reported loss during the transfer to the lake. These fish have been fin clipped so please fill out the catch record report on the KokaneePowerOregon.com website. Report how many of your catch were fin clipped and in the comments state the size of the fin clipped fish. This will be important data moving forward with this project. Our hopes are that this project will produce a higher survival rate and bigger fish in the future. If all goes well and the numbers increase we may be able to lobby for a kokanee bonus limit at Detroit.
Just want to say thanks to all those that have been working on this project, Bio-Oregon for donating the feed for raising the fry, the Detroit Business Association for their generous donation to the project and the Andrew Hedesh Memorial Fund for donating the funds to cover the cost of the fin clipping.
Summary of Kokanee Power of Oregon Detroit Reservoir Project 2016
For the past three years, Kokanee Power of Oregon (KPO) volunteers have been collecting monthly zooplankton samples from Detroit and Green Peter reservoirs. The purpose of this is to determine if there is sufficient zooplankton to support a healthy Kokanee population, and at this point the data indicates there is enough.
Oregon Department of Fish and Wildlife (ODFW) has been planting 100,000 fingerling (100/lb) Kokanee in June annually for several years, but very few seemed to reach adult size. The assumption is that either predation or the turbines in the dam were taking them out.
KPO volunteers developed a written proposal to ODFW offering to pay for the food to grow the Kokanee to a larger size prior to release in the lake to see if more of them will survive to adult size over the next 3-4 years. In March, 2016 a meeting was held with ODFW, Washington Department of Fish and Wildlife (WDFW), and KPO representatives. ODFW approved the proposal and offered to raise 25,000 Kokanee at Wizard Falls Hatchery until October, 2016. Prior to release, they will be clipped to monitor success of the program in the next 3-4 years. Due to the lack of hatchery pond space this year, they will be released in October, 2016, but in future they will be held over the winter and released in March as 16 month old fish, and they may be as large as 8-9 inches. Monitoring will be accomplished by utilizing a drop box at each ramp and marina’s whereby Kokanee anglers will fill out a card reporting their catch, or via the KPO web site catch report form.
Since this meeting in March, due to the coordination efforts of KPO volunteers and ODFW staff, the company which produces Kokanee food, Bio- Oregon, has offered to donate all the needed high protein food this year, which is a value of $2500. Next, the Detroit Business Association met and after talking with KPO representatives and attending the meeting in March, decided to donate $1000 in support of this proposal and would like to assist with any future derbies held at Detroit. Lastly, to pay for the clipping of 25,000 Kokanee, the Andrew Hedesh Memorial Fund out of Bend offered to pay for all the clipping of the Kokanee, which is another $500-$1000 value. The KPO Board of Directors approved a total funding of $16,000 over the 3-4 year life of this project, but due to the donations offered, it will cost very little of anything this year.
This is only one example of likely opportunities to enhance Kokanee fisheries. KPO is dedicated to the enhancement of Kokanee in Oregon, and will continue to work closely with ODFW to develop additional projects for other water bodies as opportunities evolve. Member support in derbies and annual membership along with volunteer efforts of the board is critical to the future if this valuable fishery.
