Hey, hold it right there.
What makes you think the Yahoo! imagery and/or the contour lines shown on
the Cycle Map(these  contours are from SRTM data, not OSM) are more up to
date or more accurate/precise than the existing water body drawn in OSM?

Also, posting a map url or link to the object of the reservoir in question
could be helpful.
