The upper Raisin river, along with the lower section, is the venue for the annual Raisin River Canoe Race, scene of much Coleman canoe carnage. There are several small rapids that do require some manouvering to avoid the odd rock, or stuck canoe. Nothing really requires scouting, unless you are planning to run the dam chute at the takeout. This is usually run in the annual race, and is on the right. The dam gets hazardous in higher water.
To get to the take out; From highway 417, head south at exit 58 on the 138, signposted Saint Andrews. Turn left on county road 43, then right on county road 20 to Martintown. The river and dam should be visible on the right. If you are going to run the dam, then take a right on county road 18, then immediately left on River road. This meets the river at several places.
To get to the put in; Take county road 18 west for 10 km to Saint Andrews. Turn right at the crossroads, and there is access to the river at the bridge in 100 m. This first rapid is indicative of the rest of the run.
