Appendix A: Resources to Understand a Catchment's Water Challenges

The stoplight system was developed for this guide and may be used for an initial high-level assessment of the site’s water challenges, if local resources are available.
Below is a stoplight approach for the Santa Ana River Watershed in California in the United States, showing the gap assessment in a visual format. Each color — red, orange, and green — were determined by a quantitative threshold.
