        481A.14  DAMS -- FISHWAYS.         It shall be unlawful for any person, firm, or corporation to      place, erect, or cause to be placed or erected, any dam or other      device or contrivance in such manner as to hinder or obstruct the      free passage of fish up, down, or through such waters, except as      otherwise provided in this chapter.  Dams for manufacturing or other      lawful purposes may be erected across the waters of the state.  No      permanent dam or obstruction across such waters shall be erected or      maintained which is not provided with a fishway, except by written      approval of the director, nor shall any pumping station or plant      except sand pumping and dredging machines, in or connected with such      waters be constructed or operated except by written approval of the      director, which is not provided with screens to prevent fish from      entering the pumping station or plant.  Such fishways and screens      shall be constructed and used according to the plans and      specifications prepared and furnished by the director.  Any dam,      obstruction, or pumping plant which is not so constructed is a public      nuisance and may be abated accordingly.
