The commission may pledge the municipal, rural, and industrial water supply funds authorized by Pub. L. 99-294 [100 Stat. 418] as security for a guarantee or note. A pledge is valid and binding whenever the pledge is made. The revenues or other moneys pledged and thereafter received by the commission are immediately subject to the lien of the pledge without physical delivery or further act, and the lien of the pledge is valid and binding as against all parties having claims of any kind against the commission, regardless of whether the parties have notice. Neither the resolution nor any other instrument by which a pledge is created need be filed or recorded, except in the records of the commission.
