The old GNIS import (source of the node you merged) labeled every body of water as a 'reservoir', which the wiki defines as "An artificial body of water", which this isn't. Assuming you're doing many of these, lean toward distrusting the older elements, the only data of value on them is the 'gnis:feature_id' tag.
