New Salton Sea data hub previewed; vegetation enhancement and bale arrays cut saltation by up to 95% in pilot sites

State wildlife and water agencies and their contractors previewed a Salton Sea data hub and described integrated monitoring efforts designed to support project design and adaptive management. Panelists also presented early performance results from vegetation-enhancement and bale-array dust suppression projects that agencies say are suppressing near-surface saltation and lowering particulate-generation at treated sites.

Data hub and monitoring coordination Diego Villalobos of the California Department of Fish and Wildlife gave a preview of an ArcGIS-based Salton Sea data hub the agencies are developing to consolidate project, survey and monitoring datasets and produce public-facing dashboards and story maps. Villalobos said the hub will host project trackers, avian survey dashboards, and “story maps” to make monitoring results accessible to partners and the public. He said the hub will be an integrated platform to share standardized survey templates and visualizations; the team estimated a public launch timeframe in 2026 for a robust hub.

Air-quality and vegetation-enhancement results The Department of Water Resources and its partners presented air-quality monitoring at vegetation projects that use staggered bale arrays and irrigated planting to stabilize exposed lakebed. Senior engineer Steven Garcia summarized transect monitoring results: “We are currently seeing a reduction in saltation anywhere from 70 to 95% within treated product areas,” he told the workshop, attributing larger reductions to established vegetation.

Monitoring equipment and findings noted at the panel - Air-quality stations collect saltation (near-surface particle movement), wind direction/speed and PM2.5/PM10 concentrations in transects placed upwind, within and downwind of project footprints. - At some stations, measured saltation events were reduced from 36 minutes per event upwind to less than six minutes per event downwind after treatment; station-level reductions of 75–95% were reported as vegetation established. - Computational fluid dynamics (CFD) modeling provided a theoretical complement to field measurements, showing bale arrays could reduce PM generated from treated areas by roughly 75% under worst-case soil and wind scenarios.

Wildlife and integrated science monitoring CDFW described expanding aerial bird surveys, marsh-bird and nesting-bird monitoring, desert pupfish survey work, and plans for phytoplankton and eDNA sampling at the SCH ponds as they are filled. CDFW said fish surveys in 2024 detected few or no fish in the sea itself (consistent with recent declines) but that the agency will use aquatic surveys at the SCH ponds to guide fish introductions and management of ponds as they commission.

Discussion vs. decision - Discussion only: agencies described the data hub preview, monitoring results, modeling and next steps; no formal adoption or data-policy decision was made at the workshop. - Direction/assignment: agencies will continue to develop the hub, expand air and aquatic monitoring, and make monitoring outputs public when feasible.
