Anderson Ranch Wetlands Characterization

The Anderson Ranch Wetlands (AR Wetlands), located in Taos County, north-central New Mexico, may be at risk from changes in climate patterns, from shifts in available water supply, and from agricultural groundwater pumping adjacent to the wetlands.  To help guide management decisions, the USGS is completing an initial hydrologic characterization of the wetlands.

Fountain Creek Watershed Flood and Sediment Transport Study

The Fountain Creek watershed, Colorado, is characterized by steep channel slopes and varied land use. Spatially distributed precipitation events result in varying rates of direct runoff. These dynamics contribute to large streamflows and sediment transport, which has caused periodic flooding, and sediment aggradation and deposition in Fountain Creek and its tributary streams. The U.S....

Deep Brine Layer

In 1959, a solid-fill railroad causeway was constructed across the middle of the Great Salt Lake. The construction of the causeway divided the lake into two parts; the north (Gunnison Bay) and the south (Gilbert Bay). By 2013, water flowed from one side to the other through only two culverts near the center of the causeway. In December 2013, concern about the structural integrity of the...

Pesticide Exposure to Native Bees in Agricultural Landscapes

There is a lack of knowledge and understanding of how widespread use of pesticides may affect bees as they move across a diverse agricultural landscape. Studies have shown there are impacts to honey bees due to exposure to pesticides including neonicotinoid insecticides and fungicides, but the effects of these compounds on native pollinators are largely unknown.
