BURDEN OF PROOF. A properly filed

Statement of Claim for Existing Water Right is prima facie proof of its content pursuant to § 85-2-227, MCA. This prima facie proof may be contradicted and overcome by other evidence that proves, by a preponderance of the evidence, that the elements of the claim do not accurately reflect the beneficial use of the water right as it existed prior to July 1, 1973. This is the burden of proof for every assertion that a claim is incorrect including for claimants objecting to their own claims.
