We don't really know how many swans were on pool 8 just south of Brownsville, Minnesota on Saturday Nov. 9.  We have been there many times and estimate that there were at least 6000 in that area.  We have seen a maximum of about 20,000 there on one occasion. Their numbers should increase over the next week or so.  They will pull out for the East and South when the backwaters freeze over.  Most will winter in the Chesapeake Bay area.
