Evaluation and Development of Fish Passage Structures and Technologies

Dams can be found in just about every major river, and for good reason. Society has received many benefits like flood control, hydropower, water supply storage, and places to recreate. However, many fish and other life in our rivers can’t swim around these barriers. Often, the best spot for a fish to live and reproduce is out of reach because they can’t pass by a dam. This has not gone unnoticed...

Assessing the effects of chloride exposure on aquatic organisms

Increased salinization of freshwater systems is a growing concern, and can be attributed to a variety of factors including climate change, land-use change, agricultural practices, road de-icing, and brines released from fossil fuel extraction. Effects of increased salinization on aquatic organisms is little understood and may be vastly different among species and among different life stages.

Pre-listing Science Support in the Northeast

The background information required to support listing decisions is not always current or available, and additional information or tools to model potential future condition can greatly improve the confidence in Species Status Assessments. We are working closely with multiple partners to provide updated information, model potential outcomes, and identify key uncertainties relevant to amphibian and...

Quantifying Restoration Benefits to Native Stream Fishes

This project is a collaboration of scientists from the USGS and University of Georgia to collect and analyze data describing how small-stream fishes use habitats created through stream restoration activities. The USFWS Region 4 requested this Science Support Partnership (SSP) project as a means to evaluate the effectiveness of stream restoration (primarily in north Georgia, and potentially in...

Life History and Migration of Sturgeons in New England Waters

Sturgeons appear in the fossil record as early as the Triassic, 200 million years ago. Although most populations could once tolerate harvesting pressures, most populations have collapsed and nearly all of the 28 species alive today are listed as threatened or endangered. In New England, dams and water regulation challenge population recoveries of the two resident species, the shortnose and...
