Monte Rio

Monte Rio is a boat ramp access point on the Russian River in Sonoma County, a large river system (stream order 7) that flows northward to the Pacific Ocean. The Russian River at this location is about 116 miles from its mouth and features an average flow of approximately 2,597 cubic feet per second with an average velocity of 3.23 feet per second. The river has a moderate gradient in this region, making it suitable for various types of boating activities. This access point serves as a launching location for paddlers and boaters exploring the lower-middle sections of the Russian River.

Boaters should be aware that the Russian River maintains a consistent current typical of a large river system draining a 1,426 square mile watershed. Water conditions vary seasonally, with higher flows during winter and spring months and lower flows during summer and fall. The river's character at Monte Rio is that of a flowing river rather than a lake, so paddlers should be prepared for current-assisted travel and potential navigation challenges depending on water levels and conditions.
