The soil at the dam removal site is tested for possible contaminants to prevent leaching or erosion into the stream bed when removing the dam. The site is also being searched for any significant archeological remains before the final digging begins. The scientists and archeologists determined through the testing that it was safe to proceed with the dam removal. |

The restoration site - post restoration. Here the site is seen on an outgoing tide. The restoration increased the tidal range of the upstream side of the creek so that it was roughly equivalent to the downstream side. The culvert measured approximately 5' x 8' and was designed to provide appropriate hydrologic conditions to increase productive fish habitat. |

Looking upstream at the original culvert. The culvert was approximately 36" in diameter. Before placement of the new culvert there was an 18" tidal height differential between the up and down stream sides of the marsh. This restriction reduced available fish habitat and allowed non-native plant species to invade the marsh. |
