Idaho Code § 56-450: Health and welfare trust account.

The director of the department of health and welfare may receive, on behalf of the department, any money or real or personal property donated, bequeathed, devised, or conditionally granted to the department. Such moneys received directly or derived from the sale of such property shall be deposited by the state treasurer in a special account to be known as the "Health and Welfare Trust Account", which is hereby established, reserved, set aside, appropriated and made available until expended, used, and administered to carry out the terms or conditions of such donation, bequest, devise, or grant. Pending such expenditure or use, surplus moneys in the health and welfare trust account shall be invested by the state treasurer in the manner provided for idle state moneys in the state treasury by section 67-1210, Idaho Code. Interest received on all such investments shall be paid into the health and welfare trust account.

The director shall provide annually, to the legislative council through the director of legislative services, an accounting of the health and welfare trust account setting forth the sources, applications and balance of moneys within the account.
