Nor shall this act be so construed as to affect the validity of any district heretofore organized under the laws of this state for the purpose of cooperation with the United States under the federal reclamation law or other federal laws, or its right in or to property or any of its rights or privileges of whatsoever kind or nature; but said districts are hereby made subject to the provisions of this act so far as applicable; nor shall this act be construed to affect, impair or discharge any contract, obligation, lien or charge, for, or upon which such district was or might become liable or chargeable had not this act been passed; nor shall it affect the validity of any bonds which have been issued and sold, or issued but not sold; nor shall it affect any action which may now be pending.
