In any lease, easement, or right of entry agreement entered into whereby the department leases real property or obtains a grant of easement, right-of-way, or right of entry in real property for the purpose of exploration for, or construction, operation, or maintenance of, water projects, or for other investigations or data collection, the department may agree to indemnify and hold harmless the lessor or grantor and may agree to repair or pay for any damage caused by reason of the uses authorized by such lease, easement, right-of-way, or right of entry. Insurance may be purchased by the Department of General Services, upon request of the department, to protect the department against loss or expense arising out of such a lease, easement, right-of-way, or right of entry.
