Widgeon slough is located right by widgeaon creek at the mouth of Pitt Lake. If you canoe across from the boat launch in Garabaldi Park you are at the entrance to the creek. Follow the creek up stream (or down depending on the tide) until you come to a fork in the creek. if you take a left you will be in widgeon slough, if you go right you will follow the creek toi the campsites. The slough allows motorboats at a speed restriction while the creek does not. The other entrance to the slough is south of the widgeon creek entrance (about 300 yards or so). I have had some fun with the bass in there on my fly rod but you can also catch lots of pike minnows and there are some cutties/bows/dollies that can be found in and around the slough/creek/mouths.
