- On February 13, 2012, MRWC Chair Tom Whittier gave a talk at the Corvallis City Club about the Marys River Flood of 2012. The river left its banks and reached its highest stage in almost 75 years of monitoring. Flooded roads caused detours and isolated area residents while water covered farm fields and lapped under homes. These events were of particular interest to members of the Marys River Watershed Council (MRWC), which has been focused on water quality, fish passage and education since its founding in 1996. Thom discussed the historic runoff event and MRWC’s work to improve the 190,000 acre watershed. You can LISTEN to Thom’s talk and the first and last questions (all in .mp3 format).
