Module
Please note that these materials have not yet completed the required pedagogical and industry peer-reviews to become a published module on the SCORE Network. However, instructors are still welcome to use these materials if they are so inclined.
Introduction
Each year, the Raisin Region Conservation Authority (RRCA) holds the Raisin River Race. This race is one of the longest races in Eastern Ontario, spanning almost 19 miles (30 km) on the Raisin River, from St. Andrews West to Williamstown. Paddlers compete against each other to achieve the fastest time in their class. Classes vary by the years and are split up based on boat type and paddler/s.
The Raisin River Race can be paddled by canoes or kayaks, but stand-up paddleboards are not permitted.

Data
This activity uses the data set: raisin_river_DNF.csv
The raisin_river_DNF.csv
data set includes data from Paddlestats and the Raisin River Race website about the Raisin River Race from the years 2015-2025 (excluding 2020 and 2021 as no race was held due to the COVID-19 pandemic and 2019 due to incomplete finish status data). Each row contains the year, the flow from that year, and the proportion of DNFs from that year (calculated by dividing number of DNFs by total number of participants).
