Field notes
The map separates dry-season diversion from rainy-season storm behavior, lets readers move from the coast through border infrastructure into Tijuana’s system, and can display planned and proposed projects. At the PB-CILA station, the page lists roughly 15 MGD arriving against 23 MGD capacity and says the pumps shut off above that level to protect against sand and trash. It labels flow figures approximate averages from public reports as of September 2026.
