distribution system.

Oswego.
Commissioner Woodard asked if ASR well no. 3 is capped and inquired if it will become
operational in the future.

Improvement Plan (CIP) list.

Mr. Goodrich replied the current water rights issues has not been resolved to date. He
went on to say if the Clackamas River is decreased by 10-percent and a water restriction
is required, Lake Oswego would issue a curtailment notice,where Tigard probably will
not (provide notice), but would activate an aquifer storage and recovery (ASR).

Mr. Goodrich replied there is 177 mg in ASR well no.2, and 77 mg in ASR well no. 1.
Commissioners Henschel and Woodard inquired on the ability to operate ASR well no.

Mr. Goodrich replied 100 million mg are available for additional storage and the cost to
complete the project may be up to $3 million.
Mr. Goodrich went on to say the current temperatures in the Clackamas River is 58-
degrees and with the lower temperatures reduces the risk of algae blooms and flow is at
697 cubic feet per second.
Commissioner Inman responded that in the previous meeting minutes, it is noted that a
flow of 750 cubic feet per second would require a curtailment.

all conditions were met with number of days the flow rate was met. He went on to say if
