90.14 RCW, deeds, documents related to issuance of a land patent, aerial photographs, decrees of previous water rights adjudications, crop records, records of livestock purchases and sales, records of power use, metering records, declarations containing testimonial evidence, records of diversion, withdrawal or storage and delivery by irrigation districts or ditch companies, and any other evidence to support that a water right was obtained and was not thereafter abandoned or relinquished. The evidence filed may include matters that are outside the original adjudication claim filed, and within the date set by the court for filing evidence, the claimant may amend the adjudication claim to conform to the evidence filed. Thereafter, except for good cause shown, a claimant may not file additional evidence to support the claim.

90.03.160(3) provide for a later date. Simplified procedures for claimants of small uses of water under RCW
