July 2018 Dredge Update

April 9, 2014 Google imagery shows the 16-acre permitted pond before the Amphibex 400 work. Orange lines represent future or existing containment and the limits of the work area. The small-dredge acre was completed and growing.

January 16, 2016 Google imagery, 2 months after the NFWF project filled the remaining pond by the Amphibex 400 small dredge.

The most recent drone imagery on July 18, 2018 revealed a well evolved marsh restoration area after 2.5 years with new habitat and naturally developed waterways. The surrounding marsh benefited by sediment overflow and is more cohesive and vibrant. The reduced tidal prism (water trying to move in and out with the tide) has reduced the amount of scour and allowed the substrate to accumulate sediment and vegetative cover. A wet spring combined with low water levels was conducive to widespread marsh expansion throughout the area. The remaining, shallow and sheltered pond within the project area are highly utilized by a variety of birds and wildlife.
