Dropping the Bass: Stopping the spread of smallmouth bass in Grand Canyon
On a scorching day in June 2022, the summer Lake Powell reached its lowest water level in five decades, National Park Service staff caught baby smallmouth bass in the lower Colorado River.
B-Roll of Lees Ferry
A collection of video for use in products related to the USGS's streamgage at Lees Ferry. The USGS installed the Lees Ferry gauge 100 years ago, and the data collected since have become critical to monitoring water availability in the West.

WHAT YOU TAKE AWAY - A Colorado River Reflection
Meet Katie, one of the 40 million people who depend on the Colorado River. Pondering life after high school, Katie finds comfort in reflecting on her time in one of the Nation’s most iconic National Parks.

Animal Interactions at Wind Energy Facilities – Gray Fox
There were two documented gray fox visits at the burrows, making them the third most documented predator. Gray foxes are implicated predators of various life stages of desert tortoises, but it is difficult to catch them in the act. In this case, a gray fox approaches a burrow, and thoroughly investigates the burrow mouth.

Animal Interactions at Wind Energy Facilities – Western Spotted Skunk
There was one documented skunk event captured on camera - the least documented predator. Here, a western spotted skunk is thoroughly investigating the burrow of one of the marked female tortoises in the study population. Western spotted skunks are known predators of turtle eggs.

Animal Interactions at Wind Energy Facilities – Bobcat
In this video, a bobcat approached a desert tortoise (a marked female in the study population) that was sleeping on the apron of her burrow. Bobcats are known predators of various life stages of the desert tortoise. In this case, the bobcat bent down to sniff the tortoise, and then touched its paw to the top of the tortoise's shell.

Animal Interactions at Wind Energy Facilities – Coyotes
Coyotes were the second most frequently observed mammalian predator on the trail cameras. Coyotes are considered one of the primary predators of desert tortoises. In this instance, a coyote is passing by a burrow when it suddenly has a change in attention as it is passing by.

Animal Interactions at Wind Energy Facilities – American Black Bear
This American black bear and cub duo was seen simply investigating a tortoise burrow, and although it is surprising to see a black bear so low in elevation, it isn't impossible. The study site, Mesa, sits at the intersection of multiple ecosystems (Sonoran Desert, Mojave Desert, montane, and coastal sage scrub).
