Portage River Kayaking Guide: Launches, Dams & Flows
A historic trade-route river through southwest Michigan farm and wetland country, finishing on the St. Joseph River in downtown Three Rivers.
River History
The Portage takes its name from the French word for carrying canoes overland. Potawatomi, Ojibwa, Ottawa and French traders used it as a trade route, and in 1802 a battle under Chief Elkhart was fought on its banks, now marked by a plaque in Three Rivers.
In 1831 John Vickers dammed Portage Creek for a gristmill, founding Vicksburg. After the Civil War, Dutch and Low German farmers drained wetlands for celery, and paddle-wheel steamboats carried goods on the river into the early 1900s.

River Overview
The river rises at Portage Lake east of Kalamazoo and flows about 39 miles past Vicksburg and Parkville to the St. Joseph River in Three Rivers.
The lower river averages about 50 feet wide and 1–3 feet deep, with a sand and gravel bottom and some deeper holes. Banks are lined with hardwoods through farmland and scattered swamps.
USGS Flow & Water Conditions
Check the Vicksburg gage. Low water leaves multi-channel sections south of South Fisher Lake Road shallow and easy to run aground.
If the USGS map doesn't load on your device, use the live gage links below.
