Consider a proposal to invest $8.55 million into a stretch of wild river preservation in Wyoming. The project would require periodic capital expenditures as well as annual maintenance expenditures. Benefits from river restoration range from current recreational use to flood prevention to potential future fishing and floating benefits as well as societal benefits from knowing wild stretches of river exist and will be passed on to future generations. Following current best practices for benefit estimation, the following set of costs and benefits are reported for the project.

Year	Time Period	Capital Costs	Maintenance Costs	Recreation Benefits	Flood Prevention Benefits	Reserve the right to fish the river benefits	Reserve the right to float the river benefits	Benefits from knowledge the stretch of river system is preserved	Benefits from leaving preserved river system to future generations
