Addedd: Zep's way in the post below is a much better way
Try this although it may get denied.
1) Zoom to the location on Google Maps
2) In the bottom right hand corner of the window click "Send Feedback" It is is very small print next to the scale. (I am using Chrome may be different in another browser)
3) Upper left, click "Report a Data Problem"
4) Select location on map that needs changed, aka the lake/pond
At that point you should be able to tell them what to change. Good luck, I think they randomly select what to approve and disapprove, you know eeny, meeny, miny, mo.
You will have to do this for each mapping site individually; Mapquest, Bing Maps, Apple Maps, and all the companies that deal in car navigation.
