Flooding Eases in Eastern Oregon

May 16, 2011

We mentioned a week ago that flooding was possible late this Spring with the heavy snowpack in the mountains.  Then heavy rain developed Saturday and Sunday in Washington and down into parts of Eastern Oregon.  Roughly a line from about Seattle down to Burns.  Very impressive rainfall amounts…one to two inches in the desert areas of southcentral Washington and northcentral Oregon. 

In our viewing area we still have two rivers under flood warnings:  the Grande Ronde in NE Oregon and Lower John Day in northcentral Oregon.  That river caused over a million dollars damage in Grant County around John Day.  The crest has moved down below the John Day Fossil Beds now with the crest at Service Creek just about now.  It’s the 4th highest level ever recorded at that location, within 2 feet of the big 1964 flood.  That’s going to be some muddy water pouring into the Columbia River!

Farther east, as you see in the graphic above, the Grande Ronde River (at Perry) near La Grande crested earlier today at it’s highest level on record.  That’s impressive, although I haven’t seen any reports of damage or widespread flooding in the Grande Ronde Valley yet.  If you have pics send them to photos@kptv.com

For the rest of this week, pretty quiet weather with just a chance for a shower tomorrow and then probably dry Wednesday-Friday.  Looking at the maps I’d say it’s pretty typical May weather, which of course is nicer than we are used to this season.

Farther ahead…it’s back to cool and wet next week, so I’m holding off on planting any warm weather veggies.
