Service Description:
Surface Water Management
Surface water in our rivers, streams, and wetlands is an essential resource for people and birds. This water is managed through a complex network of dams, water diversions, canals, and other infrastructure that makes water available to people. By carefully designing and operating this infrastructure and using water more efficiently, we can ensure that surface water provides the greatest benefit to people and wildlife.

Processing
We mapped the current footprint of surface water management as a binary surface by identifying 3-km cells with high levels of river fragmentation, flow disruption, and/or dam density (combined average of 0.65 or greater on a scale of 0-1), or where highly regulated rivers are located. Highly regulated rivers are defined here as those which have a degree of flow regulation > 10 on a scale from 0 to 100 (Grill et al. 2019).

Most Relevant IUCN - CMP Unified Direct Threat Classification
7.2.2. Operation of existing dams
7.2.4. Overuse of surface water
7.2.5. Changes to natural hydrologic flow
