Page 27 on your DeLorme Map. This section of Mount Vernon Creek is south of the town of Mount Vernon. It is the first access point on the western side of the highway, but north of the bridge just after the big bend in route 92.
From the parking lot, you must trudge through shoulder-high weeds for 300 yards in order to get to the creek. They day I visited it was misty and the weeds were soaked. As you can see from the photo, the creek was quite clear with eelgrass plentiful. I tried scuds and prince nymphs to no avail.
