Section 80. Supplying deficiencies of water

Whenever the navigation of any
  part of the canal system is endangered by  reason  of  a  deficiency  of
  water, the corporation shall, without delay, supply such deficiency. For
  that  purpose it shall resume the temporary use of all the surplus water
  leased, licensed or withdrawn under revocable permit from  the  part  of
  the  canal  system  where  such  deficiency  exists. If there still be a
  deficiency of water, it may enter upon and use all  lands,  streams  and
  waters  which, in its judgment, may be necessary or proper to be used to
  procure a temporary supply of water for such part of the  canal  system.
  The  corporation may enter into an agreement with the owner or owners of
  any property used for such temporary purpose under this section covering
  the amount of damage sustained. Such  agreement  when  approved  by  the
  attorney-general  shall become an obligation of the corporation and paid
  from moneys available therefor. In case no agreement is consummated  the
  amount of damages sustained may be determined as provided in section one
  hundred  twenty of this chapter. No damages shall be allowed in any case
  for resuming the use of any surplus water which has been withdrawn under
  lease, license or revocable permit.
