Engineering on Coral Reefs with Emphasis on Pacific Reefs, Figure 5
The fall and rise of the estuary and coral reefs in Pou Bay, Chuuk Lagoon from 1935–1980: (a) Before
1935 Pou bay was a productive estuary, mangrove forest, seagrass bed, coral reef, and shellfish bed with adjacent villagers dependent on it for subsistence. (b) Then
the Japanese built a road causeway across the mouth of the bay that polluted and degraded the ecosystem because culverts placed through the causeway were
inadequate in size and number. (c) Mandated by U.S. environmental laws and regulation, reconstruction of the causeway required installation of larger culverts which
in turn helped restore the bay’s marine ecosystems by 1980.
