This calculator is primarily designed to facilitate the calculation of how much water may be protected instream though instream leases and transfers. However, the calculator can also be used to determine the rate and duty associated with other transfers and cancellations. For questions regarding its use, please contact Laura Wilke at 503-986-0884.

The transmission loss associated with this right is not transferable or protectable instream. The following tables show the amount of water that is protectable for Instream Leases and Instream Transfers, under the October 31, 1900 priority date. (Please contact the Department if you prefer to protect water instream under the combined October 31, 1900 and December 2, 1907 priority dates.) To prevent enlargement and injury, the instream use has been modified from the authorized season of April 1 through October 31, to April 1 through October 26.
