Interior and the management team for a watershed pilot shall set and publish minimum per-unit outcome prices. The participating federal department or agency shall enter into a pay-for-performance contract to achieve outcome-based goals described in the plan developed for the pilot. Interior shall submit specified annual and five-year reports to Congress.
