The final report for the Portland General Electric (PGE) Lower Deschutes River Macroinvertebrate and Periphyton Study was presented on April 6th and 8th at meetings hosted by PGE. R2 Resource Consultants of Redmond, Washington conducted the study, which was completed under contract to, and funded by, PGE. You can download a copy here.

This is a two-year study conducted over two months (April and October) each year starting in October 2013. The study was a required condition of the Federal Energy Regulatory Commission licensing of the Pelton-Round Butte Hydroelectric Complex. The study described finding, “post-Selective Water Withdrawal conditions similar to pre-Selective Water Withdrawal, or improved.”
While landowners and recreational users of the river may have a different view of the condition of the river, it will take some time to digest PGE's study results. The Deschutes River Alliance is currently reviewing PGE's findings and comparing them to the extensive data that the DRA has compiled. There seems to be differences between studies and interpretation of results. Look for more information about these findings from the DRA in the future.
This Selective Water Withdrawal is PGE's only plan for the operation of the Dam complex on the lower Deschutes at this time. Those of us who know the river have seen the changes this SWW has brought about and they are not good for the longterm health of the river. Anglers, boaters, hikers, birders, landowners and other user groups need to be aware of this issue and get involved with this effort to save the Deschutes. The Deschutes River Alliance needs our help to make sure the Deschutes is a strong and healthy river for generations to come. Please donate your time and money to help save this very important part of Oregon.
