This is a photo of a dam in the lower Yakima River. Efforts to ameliorate the negative effects of diversion dams on aquatic species of concern are important in rivers where water withdrawal supports agricultural economies, and they are likely to become increasingly important with impending climate change. 

Survival probability estimates and 95% confidence intervals for yearling Chinook Salmon, juvenile steelhead, and subyearling Chinook Salmon at three diversion dams on the Yakima River, Washington.

Estimated relationship between entrainment probability and proportion of river flow entering canals at Wapato Dam, Sunnyside Dam, and Prosser Dam on the Yakima River, Washington. The relationships are shown at the mean total river flow for (A) yearling Chinook Salmon, (B) juvenile steelhead, and (C) subyearling Chinook Salmon.

These three thumbnail illustrations represent three different data visualizations about USGS research on how wildfire affects the Juneau Icefield, Alaska. The upper left image of the Juneau Icefield represents a viz about where the icefield is located and where scientists collect data.

These three thumbnail illustrations represent three different data visualizations about USGS research in the Beaufort Sea. The upper left image of an Arctic icebreaker and research vessel represents a viz about how sediment cores are collected.

Blue carbon refers to carbon captured in coastal and ocean ecosystems.

Two USGS scientists stand near a drought simulation study plot. The ~1/3 covering roof over the plot blocks rain and snow from reaching the vegetation to simulate drier conditions forecast for the Colorado Plateau.

Paul Henne develops wildfire models using records of past climate and area burned.  These models when combined with sedimentary records help scientists understand long-term interactions among climate, vegetation, people, and wildfire.
