As a potential next step for the Ottawa River, we recommend assessing a suitable location for a ladder at the Carillon Generating Station over the next 1-2 migration seasons coupled with a commitment to providing passage the following year. Studies conducted by Hydro QC and Milieu Inc. in 2001 and 2010 revealed that more elvers approach the southern turbines than northern ones; however, shorelines, the shipping canal, and the spillway were not assessed. It is reasonable to delay installing a permanent ladder until such assessments are completed; however, free passage should be provided by the 2019 migration season. Consideration should be given to translocating elvers captured during such assessments above the Carillon Generating Station.
