5a(1). EXPAND THE MARSH, USE A FIBER LOG FOR TOE PROTECTION
A low fetch (less than ½ mile) supports the formation of small waves, which is the ideal wave climate for marshes. Therefore, marsh expansion should be feasible at this site. A fiber log at the toe of the marsh may be necessary to hold fill in place, if used, until roots from the plants are fully established.
Even in low fetch areas, frequent, fast-moving boat traffic can generate erosive boat wakes. In these situations, a fiber log is necessary for marsh establishment. If the fiber log is not successfully holding the sediment in place, the fetch should be more accurately described as moderate (due to extensive boat activity), and a sill may be necessary.
