that migrating salmon near shore would be forced into deeper, colder
water by the 3000-foot causeway. Alaska State Department of Fish and
Game viewed a fish passage near to shore a3 the solution. Maintaining
salmon is important because subsistence fishing is a major element of
millenla-old Eskimo Inuplaq culture. Salmon fry need shallow water for
food, relatively warmer temperature and protection from predators.
The fish passage is located approximately 500 feet offshore in eight
feet of water, the most acceptable depth to meet Alaska Department of
Fish and Game requirements and also minimize maintenance dredging from
littoral drift accumulation. The breach has a bridge that is 98 feet
long at elevation+16 feet. The slope of the rubblemound beneath the
bridge results in a 50-foot opening at water level and 25-foot on the
sea floor.
These Issues were resolved through the Interagency review of the appli
cation to the U. S. Army Corps of Engineers under Section 10 of the
Rivers and Harbors Act of 1899.
Port Design Engineering Consultant
The City of Nome contracted TAMS Engineers (Tippetts-Abbett-McCarthy-
Stratton) to produce the design that ultimately was used In the contract
bid package. Ice modeling was done by Iowa Institute of Hydraulic Re
search at the University of Iowa. Preliminary design work was pre
viously done for the City by Tetra Tech.
