Los Angeles River Restoration and Access (LLARRA) Temperature Analysis - Lower Los Angeles River - 2024-2025
Listed in California Open Data
WCB Grant 2023114: Lower Los Angeles River Restoration and Access: Data includes one (1) year of temperature analysis to inform the design and serve as a baseline for restoration efforts.
Description
Two (2) sampling locations (Imperial Hwy. and Del Amo Blvd.) with direct measurement of water temperatures recorded from submerged data loggers over that time period. Data collected from two (2) locations over the course of one (1) year to capture seasonal temperature variation in the lower Los Angeles River.
Data was collected from TidbiT data loggers that were kept submerged in the low-flow channel; both Imperial and Del Amo have bridge piers located in the middle of the low-flow channel, which makes year-round submersion of the temperature sensors possible. Data was collected in support of restoration efforts in the lower Los Angeles River, specifically the Lower Los Angeles River Restoration and Access (LLARRA) project.

The project is in the planning and design phase (9/2025) and the collected data will serve to both guide restoration priorities going forward and serve as a baseline for projected beneficial outcomes of the project. The LLARRA project area is located between Paramount and Compton, roughly equidistant from the Imperial and Del Amo sampling locations. Those locations were selected for sampling due to mid-stream bridge piers that allowed sampling and measurement in relatively safe locations over the course of the work.
Temperatures fluctuated seasonally, as expected, with colder temps dipping below 10 degrees C in the winter months, and reaching as high as 30 degrees C during the height of summer. These parameters provide a clear but challenging matrix for restoration priorities. This data and metadata were submitted by California Department of Fish and Wildlife (CDFW) Staff though the Data Management Plan (DMP) framework with the id: DMP000718.
