FGUS76 KPDT 102330 ESFPDT ORZ502-WAZ523-120300- Hydrologic Outlook National Weather Service Pendleton OR 430 PM PDT Fri Apr 10 2026 ...HIGH WATER LEVELS ON THE NACHES AND GRANDE RONDE RIVERS THIS WEEKEND AND EARLY NEXT WEEK... Moderate rain this weekend in the Washington Cascades and northern Blue Mountains combined with snowmelt from above normal temperatures will lead to river rises this weekend and early next week. Most rivers are currently running at low levels and the increased streamflows will not be a problem. However, the Naches River at Cliffdell and at Naches are expected to rise above Action Stage early Saturday through Monday. The Grande Ronde River at Troy is expected to rise but stay barely below Action Stage Monday through Tuesday morning. Only localized minor flooding is expected. Please monitor the latest river forecasts from the National Weather Service for additional information. $$ GP
