We had a great salmon season and, as always, are sad the season is over. We caught quite a few big fish this year and it was a lot of fun. - Natalie
Chinook angler effort was lower in all upper Salmon River location codes this past week, but catch rates remained good. Once again the majority of anglers were found in location code 19, near Stanley. Anglers near Stanley averaged 20 hours per Chinook caught and 42 hours per Chinook kept. Fewer anglers were observed fishing downstream of Ellis in location code 17, but those who did averaged 33 hours per Chinook caught and 47 hours per Chinook kept which were the best catch rates of season so far in the Ellis area. Currently, the Salmon River is flowing at 1,240 cfs through the town of Salmon which is 34% of average for today’s date. As of Sunday, July 5th, 700 hatchery adult Chinook had returned to the Sawtooth Fish Hatchery and as of Thursday, July 2nd, 914 hatchery adult Chinook had returned to the Pahsimeroi Hatchery. Additionally, on Thursday, July 2nd, 86 hatchery adult Chinook from the Pahsimeroi Hatchery were released at the 11-mile boat ramp to provide anglers a second chance at harvesting them. Salmon River location codes 18 and 19, from 100 yards upstream of the Pahsimeroi River to 100 yards downstream of the Sawtooth Fish Hatchery weir and trap, are now closed to the harvest of adult Chinook. The harvest of jack Chinook salmon, those under 24 inches, will continue until further notice. Anglers may harvest up to 4 adipose-clipped Chinook salmon under 24 inches per day and any salmon 24 inches or longer must be immediately released. Any anglers who harvest 4 jacks in a day or have 12 jacks in possession must discontinue fishing. - Brent Beller, Fisheries Technician, Salmon Region
New Juvenile Fish Trap in the Lochsa!
We thought folks might be interested in why we have this new piece of equipment floating in the Lochsa at Lowell. The Lochsa River is a potential stronghold for wild steelhead in Idaho, though we have much to learn about this population.
Idaho Department of Fish and Game (IDFG) is working to better understand Lochsa River wild steelhead in order to protect and increase the population of this valuable species. The Lochsa River trap will be operated annually, from February to November (as water levels allow), and will be removed and stored offsite during the winter.
Juvenile rotary screw traps are important tools for fisheries managers to capture juvenile steelhead and other fishes. The traps capture juvenile steelhead leaving their natal streams on their journey to the ocean (outmigration). Fish enter the cone of the trap on the upstream side and are held in the live well on the downstream side of the trap. Traps are checked daily and biological data is collected on individual fish before releasing them to continue their migration to the Pacific Ocean
PIT-Tags are widely used to monitor the survival, abundance, and life history of fish populations. PIT-tags are inserted into many of the juvenile steelhead captured which allows us to track individual fishes movements downstream through the dams and back upstream as adults.
IDFG operates the Lochsa River screw trap to collect information on how many wild steelhead are leaving the Lochsa River, when they are leaving, how old they are, and how well they survive on their way to the ocean. These data are extremely useful in providing agencies the information needed to protect and perpetuate this valuable resource. - Brian Knoth, Clearwater Region Fisheries Biologist
Can I fish anywhere/anytime for salmon/steelhead with a tag and license if catching and releasing? Even if the season is closed/area is closed?
The Potlatch River is a smaller little known river that flows into the Clearwater River about 15 miles upstream of Lewiston, Idaho. For those familiar with this river, images of raging dirty water in the spring and barely a trickle in the summer often come to mind. At first appearance, this is hardly a river that one would consider to support any type of a quality fishery. Years of habitat degradation from farming, logging, grazing and human development has taken its toll on this river. However, about 10 years ago the Idaho Department of Fish and Game began surveying this river and what we learned was truly a surprise.
This river supported a thriving population of truly wild steelhead with almost no hatchery influence. Upon talking to some of the locals, they told stories of when their grandfathers caught steelhead in tributaries that are now dry. It became evident that this river had a lot of potential to produce more steelhead, and that is when it was decided to embark on a major habitat restoration program in this basin. To help direct where money is spent, we initiated a monitoring program to better understand where the steelhead occur, how many there are, and how they respond to the various habitat improvement projects.
We are currently in our tenth field season of studying the steelhead population in the Potlatch River basin. Much of our monitoring occurs in the East Fork Potlatch River and Big Bear Creek, two of the major steelhead producing drainages in the Potlatch. Our monitoring program consists of three major components. We trap adult steelhead at a weir to estimate how many spawn. We use two rotary screw traps (see picture to the right) to catch juvenile steelhead to evaluate the number of smolts that migrate to the ocean each year. And we use PIT tag arrays to learn when adult and juvenile fish implanted with a small microchip enter or leave certain streams. By using at all this data, we can assess steelhead survival and how well the habitat restoration program is working.
Adult steelhead travel over 500 miles from the Pacific Ocean to spawn in tributaries of the Potlatch River. Since 2008, we have estimated between 71-106 adult steelhead return annually to the East Fork Potlatch River to spawn. In 2014, we estimated 96 adults returned to the East Fork which is the 3rd highest return to date. In one of the strong run years, we believe around 1,000 adult steelhead entered the Potlatch River to spawn somewhere in the watershed.
Juvenile steelhead leave the Potlatch River tributaries typically from March-June as they begin their journey to the Pacific Ocean. We monitor this outmigration and estimate the number of juveniles departing from Big Bear Creek and the East Fork Potlatch River drainages. In 2014, we estimated approximately 8,356 juvenile steelhead out-migrated from the Big Bear Creek drainage and 11,126 from the East Fork Potlatch River drainage. These estimates are typical and have ranged from 7,000-48,000 in the East Fork and 4,000-20,000 in Big Bear Creek. The picture below shows our crew PIT tagging juvenile steelhead.
We will continue to monitor and evaluate the steelhead population in the Potlatch watershed as habitat restoration efforts continue. The IDFG, Latah Soil and Water Conservation District, Natural Resource Conservation Service, US Forest Service, and Nez Perce Tribe have made significant efforts to improve habitat in this watershed. These efforts help insure this steelhead population will thrive for years to come and ultimately provide new fishing opportunities for anglers. - Jason Fortier, Senior Fish Technician, Clearwater Region
The Salmon River cleared up this past week as flows began to decline, and as result, catch rates improved considerably. Angler effort was very low downstream of Salmon, in location code 16, but the few interviewed anglers that were out averaged 2 hours per steelhead caught and no steelhead were kept. Upstream, in location code 17, angler effort was approximately half of what was observed during the previous week, and interviewed anglers averaged 14 hours per steelhead caught and 20 hours per steelhead kept. Above the Pahsimeroi, in location code 18, interviewed anglers averaged 8 hours per steelhead caught and 30 hours per steelhead kept. Once again, the majority of anglers were observed above the East Fork in location code 19. Anglers in this area continued to do well and averaged 9 hours per steelhead caught and 30 hours per steelhead kept.
Currently, the Salmon River through the town of Salmon is flowing at 1,680 cfs which is 114% of average for today’s date. The river is running clear and temperatures in the low to mid 40s were recorded throughout the week.
As of Thursday, April 9th the Pahsimeroi Hatchery had trapped 3,441 steelhead, while the Sawtooth Hatchery had trapped 3,240 steelhead. Additionally, Blue Mountain Pond in Challis was stocked with 150 adult steelhead on Tuesday, April 7th. Check Harvest Report for more details. - Brent Beller, Fisheries Technician, Salmon Region
Angler effort continues to decline on the Main Stem of the Clearwater and lower Salmon River as the Spring 2015 Steelhead season nears its end. Most of effort this past week occurred on the Little Salmon River and on the South Fork of the Clearwater. The South Fork of the Clearwater produced the best catch rates of 2 hours/fish caught. Check Harvest Report for more details. - Amanda Schmidt, Fisheries Technician, Clearwater Region
Since 2010, Idaho Department of Fish and Game has been recruiting anglers to catch adult steelhead from the South Fork Clearwater River. These fish are being collected to develop a stock of steelhead that are more adapted to this river than fish used in the past (steelhead collected at Dworshak Hatchery). Our hopes are that the offspring from these fish will survive better resulting in more Steelhead returning to the South Fork Clearwater River in the future.
Typically we usually use weirs to trap adult steelhead to meet our brood stock needs. However, we don’t have this option in the South Fork Clearwater River, so we have turned to the angling public to collect the brood stock for us. Each year starting around the last week of February, IDFG personnel begin recruiting volunteer anglers and distributing tubes (see picture to the right) to capture and hold adult steelhead. Volunteers place hatchery steelhead they catch and want to donate to the program in a holding tube and place it in the river. Personnel from IDFG’s Clearwater Fish Hatchery operate transport vehicles and drive along the river collecting tubed steelhead that will be used as brood stock .
When the program began in 2010, the goal was to understand whether we could use anglers to catch steelhead from the South Fork Clearwater River, successfully spawn them, raise their offspring, and release these offspring one year later (as smolts) back to the South Fork. Initially we started with a goal of collecting 50 spawning pair. One year later (2011) we increased our goal to collect approximately 100 spawning pair to produce about 400,000 smolts. Due to our past success, this year Idaho Department of Fish and Game set a goal to collect enough spawners (225 spawning pair) to fulfill the entire 1.2 million smolt release goal in the South Fork Clearwater River.
In order to accomplish this goal, IDFG began soliciting volunteer anglers to collect brood on February 13, 2015. Idaho Department of Fish and Game with assistance from the Nez Perce Tribe was able to enlist more than 100 volunteer anglers to participate in the South Fork Clearwater River localized brood program this year. Due to the warmer weather, steelhead seemed to be more spread out than in previous years, and anglers were successful in capturing fish from Stites on highway 13 all the way upstream to Mt. Idaho on highway 14. Steelhead collected were placed in IDFG transport vehicles, and at the end of each day were hauled to Dworshak National Fish Hatchery where they were held until spawning.
We are proud to announce that the Idaho Department of Fish and Game with assistance from the Nez Perce Tribe, Dworshak National Fish Hatchery, and most notably the public were able to accomplish our goals of collecting 225 spawning pairs by March 7, 2015. These fish have all been spawned; and if all goes as planned, this will allow us to release about 1.2 million localized steelhead smolts into the South Fork Clearwater River in the spring of 2016.
As smolts from previous brood stock collections return as adults, we will be able to compare adult return success from fish produced through the localized brood stock collection and the adult returns produced through other hatchery strategies.
This project would be impossible without the participation of the angling public and the fish they collected. Many volunteers went above and beyond to help the project, some going so far as scheduling their vacation around this effort! Many thanks to all the volunteers who participated! - Jaime Robertson, Fisheries Technician, Clearwater Region
The South Fork of the Clearwater had the highest amount of effort this past week with the Little Salmon River not far behind. Both areas had good catch rates. Effort increased on the North Fork of the Clearwater from the previous week and produced good catch rates. Water levels increased over the weekend on the South Fork of the Clearwater and of the main stem of the Clearwater but the hydro graph looks like water levels may stabilize. The main stem of the Salmon River water level was continually fluctuating and from what the hydro graph shows the water level is going up again. For more details go to the Harvest Report. - Jaime Robertson, Fisheries Technician, Clearwater Region
