571—90.4(456A) Infested waters.

1. 90.4(1)  Designation of infested waters. The department will designate infested waters of the state and publish the names of infested waters in the fishing regulations brochure and on the department webpage, www.iowadnr.gov/programs-services/aquatic-invasive-species, and will provide notice through other available means where practical. At any time, the department may designate additional waters or remove from designation those waters that are no longer infested.

2. 90.4(2)  Restricted activities on infested waters. The department may restrict boating, fishing, swimming, and trapping in infested waters of the state. When determining when to restrict activities in infested waters, the department will consider:

   1. a. The extent of a species’ distribution within the state;
   2. b. The likely means of spread for a new species; and
   3. c. Whether restrictions specific to infested waters containing a specific species will effectively reduce that species’ spread.
