Hi, user_5359! 
My name is Oscar Medinilla and I’m a mapper in the OSM team at Lyft.
You are right, I apologize for any inconvenience caused by my edits. I really appreciate your help by bringing this mistake to our attention. 
I removed the non exist pond in this changeset (https://www.openstreetmap.org/changeset/174967691)
