As I discussed in this post, Tumalo Irrigaion District is asking taxpayers to pay the full $42M+ cost of piping their irrigation canals. They claim in their Draft Environmental Assessment that piping will conserve about 48 cfs (page xxvii) which they will return in-stream. BUT, page D-20 of the appendix contains a table showing increased water deliveries to irrigators after piping is complete. Where does this water come from? Why is it not being returned to the river? Why is on-farm conservation not being pursued to REDUCE usage? You have until May 22 to submit your comments.
