All income realized from properties under the jurisdiction of the Department of Natural Resources shall be paid into the State Parks Fund, except that income realized from properties managed and operated principally as wildlife, forestry or fisheries areas shall be paid into the Wildlife and Fish Fund. All income realized from violations of this Act, other State laws and related regulations, or local laws within such properties, except violations of the Fish and Aquatic Life Code or the Wildlife Code, when such income is derived from fines, penalties and other actions of county or municipal law enforcement personnel, may be retained by the county or municipality where the violations occurred.
The Department of Natural Resources may, upon written authorization of the Director of the Department, establish local bank or savings and loan association accounts to temporarily hold this income. All local bank or savings and loan association accounts established pursuant to this Section shall be in the name of the Department of Natural Resources and shall be subject to regular audits. The balance in a local bank or savings and loan association account shall be forwarded to the Department of Natural Resources for deposit with the State Treasurer on Monday of each week if the amount to be deposited in a fund exceeds $500 or within 30 days after deposit.
No bank or savings and loan association shall receive public funds as permitted by this Section, unless it has complied with the requirements established pursuant to Section 6 of the Public Funds Investment Act.
