SUMMARY: The District completed the Carmel River Instream Flow Incremental Method (IFIM) Study and associated 1-dimensional and 2-dimensionsal hydraulic models in November 2017. Subsequently, the National Marine Fisheries Service (NMFS) conducted additional review of the study and had several comments and concerns about its use in evaluating alternatives for management of Los Padres Dam. This item is to request $20,000 to address NMFS comments, revise the IFIM study, and to allow expenditures to revise the IFIM model in response to information provided from ongoing analysis of Los Padres Dam alternatives.
If this item is adopted with the Consent
Calendar, the General Manager will be authorized to expend up to $20,000 for
support from Normandeau Associates, Inc., for
continued development of the Carmel River Instream Flow
Incremental Method Study.
RECOMMENDATION: Staff recommends approval.
DISCUSSION: The Board has authorized $251,000 over the
previous five fiscal years to develop the Carmel River IFIM Study, which was completed
in November 2017 after input on all aspects of the study and review of draft
products by California American Water, California Department of Fish and
Wildlife, and the National Marine Fisheries Service. In November 2017, NMFS chose to carry out another
review by staff who had not been involved in the project previously. Their review resulted in several comments on
the study that will need to be addressed.
The IFIM model may also need to be modified for use with some of the
alternatives that are being considered for Los Padres Dam. In particular, dam removal may result in
channel changes downstream of the dam that are outside of the range of
conditions that the present IFIM model can evaluate.
IMPACTS ON STAFF AND RESOURCES: District staff will be involved with project
management and ongoing discussion about use of and results from the IFIM model.
