Sheet Harbour Consolidated School, formerly located in Sheet Harbour, as well as Lakefront Consolidated School in
Tangier, used to be feeder schools of DMHS, but were closed in 2017 and 2019 respectively as a part of the plan to replace the schools in the Sheet Harbour area. Eastern Consolidated School, in
Moser River, used to be another feeder school of DMHS, but was closed in September 2015 as a consequence of a very low student population. The school's official mascot is Eddy the Eagle, the team name is the Eagles and the school's official colours are gold and black.
