In the first phase of restoration, the park service installed the bridge and culvert so the water and fish could flow freely with the tides. And that has made all the difference.
Initially, before they put in the bridge. They found 10 salmon total. And then then when we came back the next year, we found 122 salmon.

Salmon in particular, they are an anadromous fish, and they are dependent on the fresh water and the salt water. So having these habitats here in the lower estuary in particular gives them a place for refuge to rear and to feed on their way out to sea, and that can be very important.
