Los Angeles Plain

July is the month when Ballona Creek — its estuary and wetlands — shows the full cost of being a federally impaired system. Low flows concentrate whatever water remains; heat strips away dissolved oxygen; and nineteen facilities currently operate in violation of their discharge permits. The creek's own recovery trajectory remains unclear, with six nearby waters still without finished remediation plans.Western sycamores stand in full summer leaf along the banks — their canopies now among the few buffers the system has left. They offer shade where the creek itself can no longer offer sanctuary. It is a portrait of ecological triage: what survives here does so partly because it has learned to live in a place that was never meant to be this compromised.

Elegant Terns have been sighted 14 times since April hunting these waters, dispersing north from Isla Rasa where nearly the entire global population nests. The birds follow fish migrations — a sensible ecology — but the fish themselves carry a hidden cost. The hunting grounds here have been formally listed as impaired for more than two decades, and no cleanup effort has been completed.This creates a direct pathway for contaminants to reach the colony. Elegant Terns are trophic foragers; they concentrate whatever toxins accumulate in the small fish they prey on. When they return to Isla Rasa to feed their chicks, those same contaminants arrive in the food the young birds consume. The colony's resilience depends entirely on the ocean remaining relatively clean—a condition that has not held for at least twenty years.
