Official sources
A South Dakota fishing license is required. Missouri River reservoir rules for Lake Oahe differ from inland lake rules and from Black Hills trout waters. North Dakota fishing rules do not apply on this South Dakota water. Check the official Missouri River regulations for seasons and limits.
Monitoring limitations
- No direct water-temperature gauge is assigned to this reservoir, so pool temperature is not part of a live station report for the lake.
- Live discharge is not published for the reservoir pool, so river-style flow is not a lake reading here.
