However, FMCC would like to pursue grant funding to construct siphon vaults and accelerate canal lining to reduce maintenance, improve safety, and reduce seepage. It is estimated that seepage could be reduced by 0.95 CFS for each canal mile that is lined. In addition, an estimated 0.5 acre-feet of water each year could be saved each year by automating the Fire Mountain Canal wasteway. Examine Alternative Water Fee Schedules Irrigation companies within the NFWCD use flat pricing structures. Water prices are determined during annual budget meetings and set on a per share basis. However, flat water rates do not accurately reflect variable costs to deliver water. FMCC experiences additional staff costs for water delivery to small users and for managing water transfers and leases. FMCC would like to examine a sliding scale pricing structure. A sliding scale pricing structure would allow FMCC to recover some of the additional costs associated with delivering water to Ismail users. In addition, FMCC would like to incorporate fees to cover additional administrative costs associated with water transfers and leases. FMCC will evaluate the feasibility of implementing varioys pricing structures. Restrict Transfer of Water Shares down the Fir<e Mountain Canal Land irrigated by the Fire Mountain Canal is not tied to specific parcels of land. Therefore, water shares can be transferred to other landowners located elsewhere on the canal. As water shares are transferred down the canal, the water delivery system runs into capacity problems. To address this issue, the FMCC would like to maintain a moratorium on future transfer of water shares. This will eliminate the problem of exceeding conveyalilGe capacity of the canal, specifically, at Roatcap siphon. , ,. Work with the D~lta County on Subdivision Review Agricultural land conversion is a growing concern within the NFWCD. Subdividing agricultural land can produce concerns for the irrigation companies. For example. homes placed near irrigation ditches can affect maintenance operations. Ditch companies would like to continue collaborating with county and city governments to minimize the impacts of subdivisions on irrigation delivery systems. While this currently may not be a pressing issue, it will only increase in the future. Irrigation companies may need to develop policies with local governments to ensure that before final subdivision plats are accepted, impacts on irrigation delivery systems are mitigated. Weed Control Noxious weed control is an ongoing concern along existing canals and laterals. The integrity of farm fields can be threatened ~s seeds of noxious weeds are transported through irrigation delivery systems. Irrigation companies also encounter resistance to herbicide application from some landowners. The private ditch companies would like to continue collaborating with the Delta County Noxious Weed Program to address outbreaks of noxious weeds. As noxious weeds are identified, private ditch companies I 3-6
