To original question...about the deer...how long areas are under water will dictate the long term affect on the deer. For the most part, IMO, deer are going to get out of the way just fine, and what food is available in these areas will determine how many come back to stay. Many of these areas will not get planted this year, if ever again, and so surviving mast trees become a good indicator of what the future resident deer pop's will be like.
