These two-day old Atlantic salmon were hatched at the USGS Tunison Lab and will eventually be released in Lake Ontario tributaries.
A new, sophisticated fish rearing facility in Cortland, N.Y. will help restore Atlantic salmon, bloater, and lake herring to Lake Ontario, strengthening the local ecosystem and economy.

Researchers use a net to pull an endangered wild manatee onto the beach in order to conduct a physical examination. Information on manatee biology in Crystal River enables biologists to better understand the complex issues confronting this fragile species.

This image of a dusty plume produced by rocks collapsing from the wall of the eruptive vent within Kīlauea Volcano’s Halema‘uma‘u Crater was captured by a USGS time-lapse camera on December 21, 2011. Vigorous spattering on the lava lake deep within the vent created the orange glow visible at the base of the plume.

Constructed channel features and changes in the Phase 1A side channel restoration area of the Kootenai River near Bonners Ferry, Idaho. The Kootenai Tribe of Idaho is managing a large-scale, ecosystem-based river habitat restoration effort that will be implemented over a period of 10 to 15 years across a 55-mile reach of the Kootenai River in northern Idaho.
