SUMMARY: Staff proposes to construct the Carmel River Steelhead Resistance Board Weir Project across from the Carmel Area Wastewater District downstream of Highway One Bridge. This project involves the construction of a 75 foot wide resistance board weir and a trap (Figure 1) for anadromous adult steelhead, which will enable the District to estimate the annual run size of steelhead. The District advertised for bids for two weeks starting on July 24, 2020. Staff will present results of the bid process at the Administrative Committee meeting.

RECOMMENDATION: The Committee should recommend that the Board
of Directors:
1. Authorize the
General Manager to enter into a contract with the
lowest bidder for construction of the Carmel River Steelhead Resistance Board
Weir Project at bid cost plus 10% contingency (Not-to-Exceed $130,000). The
lowest bid will be presented at the Administrative Committee meeting.
DISCUSSION: The Carmel River has a known run of
South-Central California Coast (S-CCC) steelhead (Oncorhynchus mykiss irideus). S-CCC steelhead were listed as a threatened
species under the Endangered Species Act (ESA) by the National Marine Fisheries
Service (NMFS) in 1997 and most of the streams in the Carmel River watershed
have been designated as critical habitat for S-CCC steelhead. Data needs to be
collected to inform management of the species as well as comply with the
National Marine Fisheries Service (NOAA) requirement that Monterey Peninsula
Water Management District (MPWMD) estimate the annual run size of SH as part of
their Section 10(A)(1)(a) permit to continue the fish rescue and rearing
program until at least when California American Water (Cal-Am) will have ceased
any unauthorized diversions and be in compliance with SWRCB WRO 95-10 and
2016-0016. Cal-Am has been recording counts of passing South Central California
Coast, Distinct Population Segment Steelhead (S-CCC) at San Clemente Dam (SCD)
and Los Padres Dams since the 1950’s. MPWMD has assisted them since 1994. MPWMD
ran a DIDSON hydro-acoustic camera for three years in the lower river to
replace the historic counts at SCD, which was removed in 2015, ending that
historic data source. That method became infeasible due to the expansion of
invasive Striped Bass expanding their use of the Carmel River, which cannot be
distinguished hydro-acoustically from S-CCC. The purpose of this project is to
install a weir (array of panels that spans the river) to collect the needed
S-CCC data to comply with NOAA requirements and inform management of the
species on the Carmel River.
IMPACTS ON STAFF AND RESOURCES: Several District staff will be involved in
the project assisting with project management, inspections and permit
compliance. The work will be performed under the direction of the Environmental
Resources Manager with possible assistance from Larry Hampson.
