Metal Contamination Aquatic Ecology of UCFR Waters

Improve knowledge of how metal distribution, abundance, and reactivity influence aquatic species diversity and food web productivity along the UCFR.

Objective 1

Understand sources, sinks, and spatial/temporal patterns of metals in the UCFR main channel and relevant tributaries.

Objective 2

Understand how floodplain land uses interact with irrigation practices, tributaries, and legacy mining to affect metal loads to the UCFR.

Objective 3

Determine how biological processes respond to interactions between metals and nutrients over seasonal time frames among and within Reaches A, B, and C.
