Lake Billy Shaw Operations and Maintenance and
Evaluation (OM, ME)
Project 1995-015

• Shoshone-Paiute Tribes
• Bonneville Power Administration

2
Project Overview

• 1988 - Feasibility Study
• 1998 - Construction as partial mitigation for
  loss of anadromous fish and loss resident fish
  habitat and connectivity
• To provide sustenance fishery to Tribal Members
• Constructed as a put-and-take fishery
• 1999 Initial filling to full pool

3
Project History

• Construction on the dam and structures was
  complete in November of 1998
• At the time, only capital construction project to
  finish on time and under budget
• Fish screen structures were complete in December
  of 1998
• Upon initial filling, dam structures, monitoring
  wells, fish screen structures, and lake level
  were monitored daily, with recordings being taken
  three times/week

4
History Cont

• June 1999 work included installation of road
  crossings around the perimeter, installation of
  boat launches, cattle guards, finish work on the
  spillway structure, pumphouse and well protection
• Invertebrate transplants w/Boise Fly-fisherman
  sportsman group
• Rip/rap around drainage areas
• Reseeded borrow areas

5
History Cont

• 2000 the Operations and Maintenance portion of
  the project began with monitoring of piezometers,
  water levels, biological monitoring, riparian
  plantings, protection of shorelines, and
  maintenance of structures and appurtances
• Completed signs
• Complete shoreline fenced including feeder canal
• Re-graded roads

6
History cont

• 800 hybrid poplars planted along shoreline
  (1999/2000)
• Public meetings
• OM ME followed with piezometer and water
  quality data in Annual Report to BPA

7
History cont

• Water temperatures, Oxygen levels, and food
  availability are more than adequate for species
  survival
• The Zooplankton and Algae Identification was
  completed in July with the help of the Pyramid
  Lake Paiute Tribe (B. Harry 2000)

8
2001 work

• 16,924 willows planted along shoreline
• 750 hybrid poplar trees (4-6 tall)
• Photo points established
• Exclosure fence complete on reservoir and inlet
  canal
• Limnological sampling continued
• Solar pump installed for off-site watering

2001 work

Stocking history

• This is a closed system as per the ruling of the
  NWPPC in 1998 prior to construction (June 5, 1998
  John Etchart to Chairman Paiva and Bob Lohn)
• NEPA documents state a habitat indicated to be
  suitable for the rainbow trout or other such
  adaptive game fish species (EA page 17)
• Has been void of fish since 1999

12
Stocking history

• Request to RFC for funds (April 2001)
• After deliberation with IDFG fish were not
  available, began searching private facility
• Will stock in 2002 with 10,714 lbs of sterile
  rainbow trout
• Well below ideal stocking stocking rate
• At least some fish in reservoir

13
Stocking Needs

• The Tribes will stock the reservoir to become a
  put-and-take fishery at the recommended stocking
  level of 160-200 fish/hectare (Kohler and Hubert,
  1993).
• With this stocking effort we would stock the
  174-hectare lake with 160-200 fish per hectare
  for a total population of 27,840-34,800 (10-12
  at 1.5 fish/lb) fish.

14
Stocking continued

• Stock with sterile rainbow trout pending results
  from Project 2000-079 (Assess Resident Fish
  Owyhee/Bruneau) and upon feasibility of project
  32001)
• At this time we will look at option of stocking
  native redband trout

Stocking Costs
16
OM, ME plans

• We will continue to follow OM plan and modify as
  needed with input from scientists and biologists
  from the region
• Will seek input from IDFG, NDOW, OSC, and others
  and agreement from ISRP and NWPPC on OM, ME
  plan

17
ME to include

• Monitor water levels
• Water quality monitoring
• Fishery surveys (upon stocking)
• Metals testing once/year

18
ME to include

• Creel surveys
• Macro invertebrate sampling
• Bird surveys
• Waterfowl production surveys
• Small mammal trapping (all 3 reservoirs) to gauge
  response to riparian enhancements
