A divisive proposal to put a marina at Bolding Mill Park in northwest Hall County is at a legal standstill. “Nothing is occurring with the marina proposal until we can determine” how a provision in a new federal water law applies to talks between the Army Corps of Engineers and Hall County over a possible park lease, said Pat Robbins, spokesman at the corps’ Mobile (Ala.) District. The Mobile District governs federal projects in the Apalachicola-Chattahoochee-Flint River basin, including Lake Lanier.
