Corps of Engineers Low Water Meeting, Thursday, may 20, 12:00-1:00


 

Lane County Parks passed this on to me. You gotta install a special program to attend. <sigh>

"PLEASE SHARE THIS INFORMATION WITH OTHERS:

"As warm, dry weather continues, the U.S. Army Corps of Engineers, Portland District is seeing a worsening water year as it strives to refill 13 Willamette Valley reservoirs for the upcoming recreation season. The Willamette Valley Project depends on spring and early summer rainfall to refill and lack of precipitation is making it difficult to fill multiple reservoirs. To help explain the situation, Corps staff will host a virtual public information session, Thursday, May 20th from 12-1 p.m.

"The Corps invites the public to attend the session to learn more about current operations, future forecasts and potential impacts to the Willamette Valley System.

"Date: Thursday, May 20, 12-1 p.m.

"The Corps encourages questions but asks participants to send any questions in through the “chat” function in the WebEx during the call.

"Year-to-date precipitation across the Willamette was 76% of normal, as of May 17. The snowpack is 51% of median for the Willamette. Snowmelt helps keep reservoir elevations up in the summer if it lasts and matches outflows – but it only accounts for roughly 10% of the system’s storage.

"The Corps manages reservoir inflows based on a “rule curve,” or the authorized maximum elevation on a given day to balance flood risk and storage for authorized purposes. The Willamette Valley Systems’ reservoirs are kept lower in the winter to reduce downstream flooding and refilled in the spring to prepare for recreation and adequate flows for fish.

"Portland District encourages the public to visit its “teacup diagrams” before heading out to recreate. Willamette River Basin teacup diagram: https://www.nwd-wc.usace.army.mil/nwp/teacup/willamette/ or http://pweb.crohms.org/nwp/teacup/willamette/.

"The Willamette Valley Project’s 13 reservoirs are currently 67% full. System-wide reservoir storage are 33% below the rule curve. Year-to-date precipitation in the Valley is 76% of normal. Willamette Basin snowpack is currently 51% of median."
