Idaho Code § 57-1202
All money paid to the county or counties in which such grazing district lies, shall be deposited with the county treasurer. The grazing district board of advisors may appoint a grazing district treasurer and the board shall give notice, in writing, to the county treasurer of the appointment. The grazing district board of advisors shall require a bond of the grazing district treasurer and may pay for the same from the fund of the grazing district. The county treasurer shall then pay over to the grazing district treasurer all funds accruing to the grazing district, from time to time, as the county treasurer receives such funds. After payment of the funds to the grazing district treasurer by the county treasurer, the grazing district and the grazing district treasurer shall be liable for such funds and all liability on the part of the state or county or county treasurer shall cease at that time. The grazing district treasurer shall deposit all such funds in a public depository, and shall expend such funds as provided for by law, and shall pay such funds out by checks signed by both the chairman of the board of the district advisors of the district and the district treasurer. In the event the grazing district board of advisors does not appoint a grazing district treasurer the county treasurer of any county in which a grazing district may be located, either in whole, or in part, shall be the ex officio district treasurer of any grazing district located in whole or in part within such county, and shall be liable upon his official bond for all money deposited in fund designated for that purpose. The county treasurer, as ex officio grazing district treasurer shall pay out such money in said fund upon the warrant of the grazing district located in whole, or in part, in his county, signed by the chairman of the board of district advisors of such grazing district and countersigned by the vice chairman. All moneys paid to any county having lands producing such moneys and not within a grazing district, shall be deposited with the county treasurer in a special fund to be known as "Range Improvement Fund" and expended by the board of county commissioners upon warrants for range improvements and maintenance, predatory animal control, rodent control, poisonous or noxious weed extermination or for any similar purpose in cooperation with the federal government or local livestock men's organizations.
