According to the North Dakota Game and Fish Department website, the Hehn-Schaffer Lake Boating Access is a concrete boat ramp that is 14 feet wide. It services Hehn-Schaffer Lake, which is a small lake located near the town of Steele, North Dakota. The website states that the lake is popular for fishing, and that the fish species found in the lake include walleyes, northern pike, perch, and bullheads.

As for the types of craft permitted on the water, the website states that there are no motor restrictions on the lake, but that boaters should use caution due to the lake's size and the potential for wind. The website also notes that the lake is not suitable for large boats, as it is only 62 acres in size.

Based on this information, it appears that the Hehn-Schaffer Lake Boating Access is a relatively small concrete boat ramp that services a small lake in North Dakota. The ramp is 14 feet wide, and there are no restrictions on the types of boats that can be launched from it, although larger boats may not be practical given the size of the lake.
