Project 3 Assessment of Steelhead Passage Barriers in Portions of Four Tributaries to the Carmel
River Main Stem
Background
The decline of steelhead in
the Carmel River Basin between the 1960s and 1990s prompted its listing as a
threatened species under the protection of the federal Endangered Species Act
(ESA). In normal and above water years,
adult steelhead can spawn in a total of 60.5 miles of stream, including 24.5 miles
of the Carmel River main stem, 30 miles of primary tributaries, and 6 miles of
secondary tributaries. A thorough,
detailed survey needs to be completed of all potential barriers to steelhead
migration. This scope of work includes
an analysis of barriers in tributary streams that are judged to be the most
important in terms of potential steelhead habitat (Figure 1). The District selected four major tributaries
for this assessment: Potrero Creek,
Cachagua Creek, Pine Creek and San Clemente Creek, and added one potential
barrier known as Flavin’s Ford.
Forty-four reconnaissance sites and a maximum of 40 sites with detailed
measurements are proposed for this barrier assessment. Of the total
reconnaissance sites, 31 are on private property and 13 are on public property.
The priorities for this
assessment will be to 1) provide a description of existing passage barriers; 2)
document and confirm the amount of stream channel accessible to steelhead in
selected tributaries under natural conditions; 3) locate, delineate, survey and
rank manmade barriers; 4) develop a prioritized list of actions/modifications
at each barrier that will ultimately maximize production of juvenile steelhead
from each tributary; and 5) recommend modifications to eliminate temporal
migration delays and any partial blockages in selected tributaries.

WORK
PLAN
Task
1: Obtain Access & Permission for
Work
Subtask 1.1 Develop parcel list and contact information of property owners along each
tributary and the main stem between San Clemente Reservoir and Los Padres Dam,
and contact each landowner for permission to conduct the assessments.
Subtask 1.2 Hold a workshop for property owners.
MPWMD will provide a parcel list and contact information of private
property owners along each tributary and the main stem between San Clemente
Reservoir and Los Padres Dam. The
Consultant is to contact each landowner and invite them to a workshop to discuss
the barrier assessments. The Consultant
will arrange for a meeting place, date, and time. MPWMD will send representatives to the
workshop to describe the project and to request that owners grant access to
MPWMD for barrier assessments.
Subtask 1.3 Negotiate agreements for access to cover the study period. If necessary, after conducting a workshop,
the Consultant will follow up with individual property owners to obtain access
permission to conduct assessments.
Task 1 Deliverables: List of property owners contacted; copies of access agreements
obtained.
Task
2: Conduct Reconnaissance Surveys and
Update Existing Information
Barrier assessment will be initiated by conducting a
reconnaissance survey of each study stream to verify previously described
barriers and identify new potential barriers.
Information collected will
include: barrier type (road crossing, steep riffle, seasonal dam, bedrock
chute, waterfall, log jam, etc.), location by Latitude/Longitude coordinates,
overall gradient upstream and downstream of barrier, initial determination of
migration constraints such as water velocity, jump height or both, and
representative photos above and below the potential barrier. To supplement previous work on the selected
tributaries, the uppermost natural barrier to fish migration will be located
and described.

Subtask
2.7 Select

Task 2 Deliverables: Geographic location data and characterization
of potential barriers.
Task
3: Detailed Barrier Assessments
This task will employ a two-staged approach based on
techniques developed by the United States Forest Service (2005 and 2008) and
the California Department of Fish and Game (CDFG) (2010). This approach will incorporate a screening
process, using site specific geomorphic and hydrologic data of barriers in each
stream, which will then be compared to a set of criteria to rank the
barriers. The protocol includes
measurements of channel profile, x-sections, substrate composition, the size
and shape of culverts or channel obstructions, flow characteristics, sketches,
and photo documentation of potential barriers.
The goal of this two-staged approach is to inventory, evaluate and rank
the sites according to the general framework recommended by the CDFG’s
California Salmonid Stream Habitat Restoration Manual. The results of the evaluation will provide
guidance on the priority for treating sites with the goal of eventually
providing unimpeded fish access to the uppermost natural total barrier in each
tributary.
