The state land surveyor or any and all employees of the department of agriculture have the right to enter upon private property for the purpose of making surveys, or for searching for, locating, relocating, or remonumenting land monuments, leveling stations, or section corners. Should any of these persons necessarily damage property of the owner in making the surveys or searches or remonumentations, the department of agriculture may make reasonable payment for the damage from funds available for that purpose. However, department of agriculture employees are personally liable for any damage caused by their wantonness, willfulness or negligence. All department of agriculture employees are immune from arrest for trespass in performing their legal duties as stated in sections 60.510 to 60.620 and section 60.670.
