Cram served as general superintendent for harbor works on Lake Michigan and the construction of roads in Wisconsin Territory. He led surveys to determine the border of Michigan and Wisconsin Territory in the Upper Peninsula, to explore Oregon and Washington Territories, and to determine the feasibility of a water route to the Pacific Ocean through Central America. He served under Major General Zachary Taylor in the Army of Occupation during the Mexican-American War and conducted coastal and river surveys in Texas.
Cram participated in the United States Lake Survey and led the survey section between Green Bay, Wisconsin, and Chicago, Illinois. He conducted multiple river, canal, and harbor improvement assessments including for the Fox and Wisconsin Rivers in Wisconsin, the Ohio River in Louisville, Kentucky, and the harbor at St. Louis, Missouri, on the Mississippi River.
