I. Project Goal

To preserve the genetic variability and enhance the population size of the depressed spring chinook salmon populations in Catherine Creek and the Upper Grande Ronde River using a hatchery program based on the indigenous stock.

RPA 177: In 2002, BPA shall begin to implement and sustain NMFS-approved, safety-net projects.
Deliverables: All of the deliverables contained in this statement of work will apply to this RPA.

II. Background

The ceded lands and usual and accustomed fishing sites in northeast Oregon of the Confederated Tribes of the Umatilla Indian Reservation (CTUIR) include areas where fish and wildlife populations have been negatively affected by construction and operation of mainstem Columbia and Snake River dams. CTUIR is seeking restoration of these populations. CTUIR, Nez Perce Tribe (NPT), and Oregon Department of Fish and Wildlife (ODFW) are cooperating in a Grande Ronde Endemic Spring Chinook Salmon Supplementation Program (GRESCSP) to increase natural production and eventually allow harvest of spring Chinook salmon in the Grande Ronde River basin. Grande Ronde Basin tributaries currently being targeted for spring Chinook supplementation include the upper Grande Ronde River, Catherine Creek and the Lostine River. The focus of this project is directed at Catherine Creek and the upper Grande Ronde River, within the ceded lands boundary of CTUIR. Adult spring Chinook salmon are captured at weirs on these tributaries operated by CTUIR and spawned at Lookingglass Hatchery. CTUIR also operates juvenile acclimation facilities for spring Chinook salmon in the upper Grande Ronde River and Catherine Creek. This project is the M&E portion of the project formerly numbered 199807003.

III. Location of Project

The project is located in the Blue Mountains of eastern Oregon. The Catherine Creek Acclimation Facility is at river mile 29 (rkm 47.5) of Catherine Creek (HUC 17060104). The Catherine Creek Adult Collection Facility is at river mile 20 (rkm 33.0) of Catherine Creek (HUC 17060104). The Grande Ronde Acclimation Facility is at river mile 199 (rkm 319.4) of the Grande Ronde River (HUC 17060104).

VI.  Summary of Major Accomplishments for the Program and Project:
This proposal is listed as new.  However, work is actually ongoing from Project 199800703.  Beginning in 2002, this project was split into two components (Operations and Maintenance and Monitoring and Evaluation) for contracting purpose.  This proposal severs the ties under project 199800703, thus resulting in this new project proposal number, even though project activities are ongoing.

1997  Adult traps were installed late in the spring Chinook salmon spawning run on Catherine Creek and the upper Grande Ronde River.  One unmarked male (729 mm FL) and one unmarked female (680 mm) were caught at Catherine Creek from July 22-26.  Five unmarked spring Chinook (2 males, 800-904 mm and 3 females, 710-760 mm) were caught at the upper Grande Ronde River trap from June 27-July5.

1998 Adult traps sampled the spring Chinook salmon spawning run more effectively in 1998 due to earlier installation.  The Catherine Creek trap captured 28 spring Chinook from June 13-Sept 28.  Peak catch (17.8% of the total) occurred June 13.  Thirteen females (mean FL 822 mm, range 690-870) and fifteen males (mean FL 839 mm, range 698-920 were collected.  The upper Grande Ronde River trap captured 33 spring Chinook from June 4-July 19.  Peak catch of 4 fish (12.1% of the total) occurred June 16.  Nineteen females (mean FL 848 mm, range 740-910) and fourteen males (mean FL 883 mm, range 710-985) were collected. All spring Chinook captured in both traps were unmarked.

1999 Extremely low escapements of spring Chinook salmon occurred in 1999.  The Catherine Creek adult trap captured 16 unmarked spring Chinook from May 13-August 25.  Peak catchers ( 2 fish, 12.5% of the total) occurred on July 2 and July 17.  Seven females (mean FL 719 mm, range 610-768), three males (mean FL 742 mm, range 730-757, and six unkown sex (mean FL 742 mm, range 665-805) were collected.  Overall mean FL for 16 fish was 732 mm and the range 610-805.  Only one unmarked spring Chinook (no data taken) was captured at the upper Grande Ronde River adult trap.

Ten unmarked summer steelhead were captured at the Catherine Creek adult trap from May 11-20.  Mean FL was 712 mm and the range was 610-805.  Three (all female) ad-clipped (hatchery-origin) summer steelhead were collected from May 19-21.  Mean FL of ad-clipped fish was 605 mm and the range 580-650.  Three unmarked summer steelhead were collected as mortalities on the weir (2) or kelt (1) at the upper Grande Ronde River adult trap.  Mean FL was 532 mm and the range was 450-600.

2000 Juvenile spring Chinook acclimated and release at both Catherine Creek and the upper Grande Ronde River facilities were significantly larger and heavier than outmigrating naturally-produced fish of the same brood year.  Median arrival dates at Lower Granite Dam were later for hatchery fish than naturally-produced fish from Catherine Creek, but the reverse was true for the upper Grande Ronde River. Minimum PIT tag detection rates in the hydropower system were higher for hatchery fish than naturally-produced fish from both streams.

The adult trap at Catherine Creek captured 24 unmarked spring Chinook salmon from May 22-July 21.  Peak catches (3 fish, 12.5% of the total) occurred on June 3 and June 26.  Five females (mean FL 741 mm, range 705-800), nine males (mean FL 747 mm, range 665-840), and ten fish of unknown sex (mean FL 732 mm, range 665-790) were collected.  Two age 3 males (“jacks”, 485 and 535 mm) were caught.  

The adult trap at the upper Grande Ronde River captured 17 unmarked spring Chinook from June 10-July 27.  Peak catches (3 fish, 17.6 % or the total) occurred on June 16 and June 28.  Nine females (mean FL 701 mm, range 658-775), seven males (mean FL 744 mm, range 660-785) and one fish of unknown sex (680 mm) were caught.

Ten unmarked summer steelhead were caught at the Catherine Creek adult trap from April 1-4.  Six females ranged from 600-745 mm FL (mean 687), and four males from 605-776 mm FL (mean 690).  Eight ad-clipped (hatchery-origin) summer steelhead were caught (7 from April 2-4, 1 kelt on May 10).  Mean FL of 5 females was 624 mm (range 570-680).  Mean FL of 3 males was 611 mm (range 595-619).

Twenty unmarked summer steelhead were caught at the upper Grande Ronde River adult trap from April 5-June 4.  Peak catches (2 fish, 10% of the total) occurred on April 27, May 4, May 16, and June 4.  Fourteen females ranged from 595-763 mm FL (mean 655) and six males from 568-715 mm FL (mean 614).  Six unmarked fish were kelts (4 females and 2 males) collected from May 26-June 21.  Four ad-clipped (hatchery-origin) males were captured from April 8-May 4.  Mean FL was 613 mm (range 597-638).

Water temperatures and stream flows were monitored at acclimation and adult trapping sites on both streams.  Below weir surveys were conducted during the adult trapping period on both streams.  Project assistance was provided to ODFW for PIT-tagging of juvenile spring Chinook salmon at Lookingglass Hatchery, collection of captive brood parr, spawning of spring Chinook salmon at Lookingglass Hatchery, and spawning ground surveys for spring Chinook salmon.

2001  Juvenile spring Chinook acclimated and release at both Catherine Creek and the upper Grande Ronde River facilities were significantly larger and heavier than outmigrating naturally-produced fish of the same brood year.  Median arrival dates at Lower Granite Dam were earlier for hatchery fish than naturally-produced fish from both Catherine Creek and the upper Grande Ronde River. Minimum PIT tag detection rates in the hydropower system were more than three times higher for hatchery fish than naturally-produced fish from Catherine Creek.  Too few naturally-produced fish wree captured from the upper Grande Ronde River to facilitate a comparison..

The adult trap at Catherine Creek captured 71 age 4 and 7 age 5 unmarked spring Chinook salmon from May 21-Sept 4.  Peak catch (10 fish, 12.8% of the total) occurred on June 10.  Forty-two females (mean FL 714 mm, range 621-856), thirty-four males (mean FL 733 mm, range 621-930), and two fish of unknown sex (mean FL 782 mm, range 682-882 mm) were caught.  Twelve unmarked age 3 fish (11 males, 1 female) were caught from June 5-July 3.  Mean FL was 536 mm (range 419-617).  Twenty-nine ad-clipped (hatchery-origin) age 3 spring Chinook were caught from June 10-Sept 4.  Peak catch (6 fish, 20.7% of the total) occurred on June 14.  Mean FL was 474 mm (range 370-546).  Fifteen unmarked spring Chinook salmon from Catherine Creek were spawned at Lookingglass Hatchery in August.  Mean FL of females spawned was 715 mm (range 617-805) and mean fecundity was 3,978.

The adult trap at Catherine Creek captured 60 age 3, 556 age 4, and 19 age 5 ad-clipped (hatchery-origin) spring Chinook salmon from May 17-August 12.  Ages 3, 4, and 5 made up 9.4%, 87.6%, and 3.0%, respectively, of the total caught.  Peak catch of pooled ages 4/5 fish (100 fish, 17.4% of the total) occurred on June 14.  Peak catch of age 3 fish (14 fish, 23.3% of the total) occurred on June 21.  Age 3 fish were caught from May 28-Aug 4.  Mean FL and ranges (in mm) for females were 705 and 621-798 (age 4) and 824 (age 5).  Mean FL and ranges for males were 518 and 418-620 (age 3), 713 and 635-800 (age 4), and 886 and 803-1000 (age 5).  Females comprised 0% of age 3 fish, 49.3% of age 4, and 5.3% of age 5.  Smolt-to-adult survival of the 1999 brood year was 0.002.

Unmarked prespawn summer steelhead captured at the Catherine Creek adult trap from March 9-June 5 totaled 181.  Peak catch (24 fish, 13.3% of the total) occurred on March 19.  One hundred and two females ranged from 505-775 mm FL (mean 635) and seventy-nine males from 515-830 mm (mean 636).  No ad-clipped (hatchery-origin) fish were caught.  Twenty-one kelts were collected from April 19-June 23.  Peak catch (5 fish 23.8% of the total) was on May 3.  Mean FL (mm) of 9 female kelts was 649 (range 561-790) and mean FL of 12 male kelts was 649 (range 547-820).  Nineteen kelts were recaptures of fish previously marked and passed above the weir.  Age composition of the run was approximately 59% 1-salt and 41% 2-salt.

The adult trap at the upper Grande Ronde River captured 5 age 3 and 28 age 4 unmarked spring Chinook salmon from May 28-July 20.  Ages 3 and 4 made up 15.2% and  84.8%,  respectively, of the total caught.  Peak catch of age 4 fish (5 fish, 17.08% of the total) occurred on June 21.  Age 3 fish were caught from May 26-July 20.  Mean FL and range (in mm) for age 4 females were 683 and 621-763.  Mean FL and ranges for males were 531 and 409-613 (age 3), and 715 and 645-791 (age 4).  Females comprised 0% of age 3 fish and 39.3% of age 4.

The adult trap at the upper Grande Ronde River captured 60 age 3, 369 age 4, and 4 age 5 ad-clipped (hatchery-origin) spring Chinook salmon from June-July 31.  Ages 3, 4, and 5 made up 13.9%, 85.2%, and 0.9%, respectively, of the total caught.  Peak catch of pooled ages 4/5 fish (80 fish, 21.4%% of the total) occurred on June 18.  Peak catch of age 3 fish (15 fish, 25.0% of the total) occurred on June 21.  Age 3 fish were caught from June 15-July 12.  Mean FL and ranges (in mm) for females were 702 and 628-782 (age 4).  Mean FL and ranges for males were 525 and 380-620 (age 3), 707 and 623-784 (age 4), and 821 and 805-846 (age 5).  Females comprised 0% of age 3 fish, 55.0% of age 4, and 0% of age 5.
