**Appendix A**

**Table A1.** Documented ecosystem services and disservices of artificial aquatic systems. This list, while incomplete, provides examples of supporting, provisioning, and cultural services and disservices, including biodiversity, for a variety of ecosystems around the world. Actual monetary valuation of ecosystem services and disservices of artificial aquatic ecosystems, particularly of net effects of waterbodies and comparisons with natural waterbodies, remain lacking, and constitute an area inviting further study.
