Hydrologic Outlook
None

ESFPDT Temperatures in the 60s and 70s through Wednesday will increase snow melt of the mid and high elevation snow pack. This will be followed by mountain rain Wednesday night through Friday. Saturated mountain soils will allow for efficient runoff and will increase water levels on mountain rivers, creeks and streams. The primary concern is the John Day River at Service Creek which is forecast to reach minor flood stage Thursday morning through Friday afternoon, peaking early Friday morning. The Grande Ronde River at Troy and the Naches River at Cliffdell and Naches are expected to reach action stage Wednesday afternoon through at least Friday morning but have a low probability of reaching minor flood stage. Several other rivers are forecast to approach but not quite reach action stage. Smaller creeks and streams may also have significant rises but at this time they do not appear to reach levels that would cause flooding. People with activities near creeks and streams should exercise caution as flows will be swift and very cold water can quickly lead to hypothermia if someone were to fall into the water. Those with interests along rivers, creeks and streams should continue to monitor forecasts as there is some uncertainty in the expected water levels. Stay tuned to for the latest forecast updates along with any flood warnings or advisories that may be issued.

The Hells Canyon Dam to Pittsburg Landing section of the Snake River in Oregon is a challenging river run with Class III-IV rapids and beautiful scenery. The best time to float this section is in the spring when the river is high with recommended CFS of 10,000 or higher. There are several river obstacles to navigate, including Granite Creek Rapid, Wild Sheep Rapid, and Devil's Tooth Rapid. Experienced rafters and kayakers will enjoy the technical runs and stunning canyon views along this 22-mile stretch.
