Are there any other pipelines under Lake Oahe?

There are currently eight other non-DAPL owned pipelines under Lake Oahe, including existing dual 42-inch pipelines that have been uneventfully operating just a few feet below the lake bed since for almost 35 years. By contrast, the Dakota Access Pipeline will be at a minimum depth of 92 feet below the lake bed, and as much as 115 feet below it at certain points.

There is also a high-voltage electrical system running across Lake Oahe.
