Oct. 3, 2005, Columbia, SC – The work being done by SCE&G to construct a fish passage, or "fish ladder," at the eastern end of the Columbia Canal diversion dam near Columbia Canal Riverfront Park will get a little louder this week. Excavation work at the site will involve some controlled blasting beginning tomorrow. SCE&G expects that the work will require one blast per day – probably between noon and 1 p.m. – for about four days.

Overall work on the fish passage is expected to last approximately 8 months. The goal is to create a concrete structure with a series of pools (think of a staircase) that will allow fish to cross over the diversion dam into the Broad River upstream of the diversion dam. While the fish passage is designed specifically for American shad and blueback herring – two migratory fish species – other species of fish may also utilize the structure.
