Modifying and altering a wetland, either by natural design or by prior human intervention, is a serious crime, which can land you in prison after a hefty fine. Best to check with the local county about the modification to the existing wetland first. Don't just waltz into the office/cold calling the office, without providing aerial info. Outline the area you're planning to take action on. Ask, and make sure to note, the person's or persons' name(s) you're talking to for future reference. A business card from that person will be you alibi if things get ugly. They will have existing tracking system (by papers or computer based) to check if your pond is indeed a designated wetland.
