Osborne Township also contains the majority of the northwest part of Jocko Rivers Provincial Park. Within the park borders are Jocko Lake, the source of the Jocko River, and two tributaries of the Jocko River (in downstream order): Black Duck Creek and (via Little Sucker Lake) Sucker Creek. Other lakes all or in part in the township are Little Sucker Lake, Malone Lake and Sucker Lake. All are in the Saint Lawrence River drainage basin.
