N.C. Gen. Stat. § 77-71
The three counties may by joint resolution create the Mountain Island Lake Marine Commission. Upon its creation the Commission has the powers, duties, and responsibilities conferred upon it by joint resolution, subject to the provisions of this Article. The provisions of any joint resolution may be modified, amended, or rescinded by a subsequent joint resolution. A county may unilaterally withdraw from participation as provided by any joint resolution or the provisions of this Article, once the Commission has been created, and any county may unilaterally withdraw from the Commission at the end of any budget period upon 90 days prior written notice. Upon the effectuation of the withdrawal, the Commission is dissolved, and all property of the Commission must be distributed to or divided among the three counties and any other public agency or agencies serving the Mountain Island Lake area in a manner considered equitable by the Commission by resolution adopted by it prior to dissolution.
