[Talk-ca] Lake Simcoe - two versions?

[Me (Gmail)]

I've been working on improving the Barrie, Ontario area, and I'm
trying to figure out what is going on with/what to do about Lake
Simcoe.

There are multiple CanVec-imported ways that together make up a fairly
detailed, accurate representation of the lake. A single low-detail way
[1] is overlapping these, and obscures the accurate detail in many
places when rendered [2].

[2]: http://dl.dropbox.com/u/2398828/lake-simcoe-josm.png

Not having much experience dealing with large or tiled objects in OSM,
my question is if the low-resolution object is serving a purpose, and
whether I should bother editing it so as to not overlap with the
high-detail version, or whether it can just be deleted.
