Texas Water Code - WATER § 62.074. Treasurer's Bond

(a) The county treasurer shall execute a good and sufficient bond, payable to the commissioners, in an amount equal to twice the amount of funds he will hold at any time as treasurer of the district.  The commissioners shall estimate the sum to be used as a basis for computing the amount of the required bond.  The bond shall be conditioned for the faithful performance by the treasurer of his duties for the district and must be approved by the commissioners.

(b) When any bonds are voted by the district, the county treasurer, before receiving the proceeds from the sale of the bonds, shall execute an additional good and sufficient bond, payable to the commissioners, in an amount which is twice the amount of bonds issued.  This additional bond shall be conditioned and approved in the same manner as the first but shall not be required after the treasurer has disbursed the proceeds of the bond issue.
