We fish a flowing river with current the level is never the same it is 7 ft one day 10 ft the next. Trying to put structure in it. We have been reading the posts most of these are for lakes with little to no current.How is the best way to anchor structure to keep the current from washing it out any suggestions.We try to locate them in the backwater out of the current. It has really been hard one day under water next day dry.Hows the best way to anchor in current? The structure we have put old tires,pallets,concrete blocks it works really good if you can keep the structure from washing out really attracts the fish espically crappie. Any sugestions thanks!!!!!
