The few artificial drains that would be required would be relatively short and inexpensive. Construction Considerations Enlargement of Savery Dam is not expected to present any urusual geological or construction problems. Special consideration would be re~uired in the design and construction of the upper portions of the Two Bar, Lily, and Deerlcdge Canals as these sections would encounter steep slopes consisting of sandstone ledges and shale cliffs. The Two Bar unit is expected to require a construction period of about 1 year. No additional construction camps would be required as camp facil- ities for the potential projects on which the unit is dependent would be available. Cost estimates Construction costs of the Two Bar unit arz estimated at $1,445,000 or ;~;;40 for each acre of land to be served. Annual operation, maintenance, and replacement costs are expected to amount to ~12,500. The estimated costs are s~rized below.
