Local Restrictions on Personal Watercraft and/or Two-Stroke Engines

State law allows local public agencies to regulate boating in certain categories: Three of those apply here and are listed below:

  1. Speed Zone
  2. Special-use Areas
  3. Sanitation and Pollution Control

A special-use area is all or a portion of a waterway that is set aside for specified activities to the exclusion of other incompatible uses or activities. Below is a list of waterways with local personal watercraft (PWC) or two-stroke bans or restrictions: NOTE: Many of these restrictions were passed because of conflicts between PWC and other boating activities, before the advent of the environmental issues with two-stroke engines. In addition, there are many other lakes (not listed here) where boating of one type or another has never been allowed.
