Da-Ku-Be-Te-De Tr940 to Payette Tr970 is a popular shoreline ride which is not as flat as the water it surrounds...just enough terrain to keep it interesting.
The elevation profile looks scary/wrong until the scale is considered. The trail traverses just above the high water mark of Applegate reservoir, passing through mixed conifer, vine maple, black oak, and Madrone forest.
The most significant ascent is about 450' at a 1% incline, although the entire trail is a typical shoreline ride, with repeated small climbs.
The brief 50' climbs add up to a 4600' ascent but most of it does not disrupt the flow of the ride.
