There shall be in each river improvement district an association to be
  known by the name of the district, as..................River Improvement
  Association. It shall be the object of this association to represent the
  interests  of  its  members  before  the department and elsewhere and to
  serve as a channel of communication between the members thereof and  the
  department.  Each  public  corporation and each owner of land within the
  district and each lessee of such land shall be a  member  of  and  shall
  have  an  equal  vote in the association. Such association may be formed
  voluntarily as soon as the department has filed its first description of
  the boundaries of the district. As soon as practicable  after  recording
  the  final  order  creating  the  district  the  association, if already
  formed, shall call a meeting of  the  members  of  the  association  and
  perfect  a permanent organization. If no association has been formed the
  department shall call a meeting for  the  purpose  of  forming  such  an
  association and a representative of the department shall preside thereat
  until  a  temporary  chairman  is  elected. Such association shall adopt
  by-laws for the transaction  of  its  business.  The  association  shall
  choose  from  among  its  members  a  president, secretary and executive
  committee and such other officers and  committees  as  the  by-laws  may
  provide.  It  shall  be  the duty of the secretary to keep a list of the
  members and their addresses and to furnish the department with a list of
  such members on request. The association  may  require  the  payment  of
  annual  dues or contributions to the association treasury, the amount of
  such contribution and the manner of collecting the same to be decided by
  the association. The annual meeting of the  association  shall  be  held
  during the month of February in each year, at which meeting the officers
  shall  be elected and the association shall determine what further work,
  if any, it desires during the ensuing year. Immediately after the  close

  year and a petition setting forth the desires of the association.
