Ecological Assessment
Habitat Observations
- Crab Burrow Intensity
- Limited (<10% banks are densely
- Ponding Depressions
- Limited(<10% of marsh platform
- Phragmites Present
- Severe (>60%)
- Ecological Impairment
- Moderate
Invasive Species
- Upstream Invasive Species
- Yes
- Downstream Invasive Species
- Yes
- Invasive Species Notes
- Large pockets of high marsh but otherwise phragmites.
- Additional Comments (2024)
- Tide gate appears to have been widened from 2 ft flapper in last inspection to 8 ft box with stop logs now. Upstream is mostly phragmites but only pockets of healthy mature phragmites exist near tide gate. Majority of phragmites is stressed, stunted and adjacent to high marsh pockets. May be an early indicator of restoration progress since redesign.

Notes & Comments
- General Comments
- Bridge replacement occured from 2005-2008. Old flap gate has been removed and replaced with 3 horizontal wooden boards. Slight tidal restriction during high tides (potentially only for astronomically high tides).
- Operation Comments
- No operating mechanism, appears to only be there for flood protection during abnormally high tides.
