The reserve boundaries as stated in the regs are very confusing, especially if unfamiliar with the site. The huntable area is basically north of the parking lot that is on Francis Rd. and east of the slough. Most folks hunt the fields, especially when planted in barley. I've also seen people hunting the slough and pond on the northwest corner of the second field in. DFW safety zoned the whole first field and swale with alders in it last year as people were raining shot down on the house nearby. This seems to be a popular spot with a few locals but gets crazy when the birds want in there. Must have been 15 or 20 trucks there last year when it was hot, all of the guys surrounding the second field, dogs everywhere, shots every few minutes, and still ducks were coming in. It'll be interesting to see if that happens again this year as that field is in potatoes, not barley like last year.
You should stop by the DFW office on Wylie Rd. on Fir Island and ask for a map or explanation on the reserve boundaries.
