Nitrogen in the Chesapeake Bay watershed—A century of change, 1950–2050

ForewordSustaining the quality of the Nation’s water resources and the health of our diverse ecosystems depends on the availability of sound water-resources data and information to develop effective, science-based policies. Effective management of water resources also brings more certainty and efficiency to important economic sectors. Taken together, these actions lead to immediate and long-term e

How will baseflow respond to climate change in the Upper Colorado River Basin?

Baseflow is critical to sustaining streamflow in the Upper Colorado River Basin. Therefore, effective water resources management requires estimates of baseflow response to climatic changes. This study provides the first estimates of projected baseflow changes from historical (1984 – 2012) to thirty-year periods centered around 2030, 2050, and 2080 under warm/wet, median, and hot/dry climatic condi

Substantial declines in salinity observed across the Upper Colorado River Basin during the 20th century, 1929 to 2019

Salinity in the Colorado River Basin causes an estimated $300 to $400 million per year in economic damages in the U.S. To inform and improve salinity‐control efforts, this study quantifies long‐term trends in salinity (dissolved solids) across the Upper Colorado River Basin (UCRB), including time periods prior to the construction of large dams and preceding the implementation of salinity‐control p

Great Salt Lake Elevations

Great Salt Lake Elevations The United States Geological Survey (USGS) has been collecting water-surface-elevation data from Great Salt Lake since 1875 and continuously since October 1902. The north part of the lake has been monitored since April 1966. In July 2021, the southern portion of the Great Salt Lake reached a new historic low, with average daily water levels dropping about an inch below...

Quantifying Nutrient Mass and Internal Cycling in Great Salt Lake

The Great Salt Lake (GSL) is an indispensable economic and ecological resource. It provides critical habitat and food for millions of migratory birds, and generates nearly $200 million per year from recreational activities and the brine shrimp harvest industry (Bioeconomics, 2012). These uses, habitat and aquaculture, rely on a balanced supply of nutrients in the Great Salt Lake to support...
