The Grande Ronde River is a tributary of the Snake River, located in the northeastern part of Oregon. It is approximately 182 miles long and has a drainage area of 6,113 square miles. The river's name comes from the French phrase "grande ronde," meaning "great circle," describing its meandering path through the mountains. The hydrology of the river is characterized by a snowmelt-dominated flow regime, with the highest flows occurring in late spring and early summer. The river is not dammed, but several small reservoirs exist for irrigation purposes. The Grande Ronde River is a popular destination for fishing, kayaking, and rafting, and its surrounding area is used for grazing and hay production. The river has historical significance, as it was a site of conflict between native tribes and settlers in the mid-1800s.
