<br />"Watercourse," "river" or "stream" means any portion of a stream or river channel, bed, bank, or bottom
<br />waterward of the ordinary high water line of waters of the state. Watercourse also means areas in which
<br />fish may spawn, reside, or pass, and tributary waters with defined bed or banks that influence the quality of
<br />habitat downstream. Watercourse also means waters that flow intermittently or that fluctuate in level during
<br />the year, and the term applies to the entire bed of such waters whether or not the water is at peak level. A
<br />watercourse includes all surface-water-connected wetlands that provide or maintain habitat that supports
<br />fish life. This definition does not include irrigation ditches, canals, stormwater treatment and conveyance
<br />systems, or other entirely artificial watercourses, except where they exist in a natural watercourse that has
<br />been altered by humans.

<br />created from nonwetland sites, including, but not limited to, irrigation and drainage ditches, grass-lined
<br />swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and landscape amenities, or
<br />those wetlands created after July 7,1990, that were unintentionally created as a result of the construction
<br />of a road, street, or highway. Wetlands may include those artificial wetlands intentionally created from
<br />nonwetland areas created to mitigate conversion of wetlands.
