MADISON (AP) -- Wisconsin water officials are urging property owners to register large piers by spring.
The Department of Natural Resources' registration requirements are linked to a 2004 law that exempted traditionally sized piers from the agency's permit process.
State legislators passed a law two years ago that extended the exemption to most larger piers installed before 2004. However, owners of larger piers that don't qualify must register with the DNR by April 1. Owners who don't' qualify for the exemption will either have to downsize or obtain a permit.
The DNR says large piers can hurt aquatic plants by blocking out sunlight, in turn harming the fish population. The agency says large piers also can interfere with boating, swimming and property owners' neighbors.
