Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Ecological Responses to Fish Reclamation Treatments

Piscicides have been used in Rocky Mountain stream and lakes to restore native fish populations. In the last two decades concerns over piscicide effects to non-target organisms, primarily aquatic invertebrates, has increased. Although piscicides have been used for more than 70 years the impact to invertebrate assemblages has not been well studied and is largely unknown. Given the importance a...

Potential Toxicity of Multiple Metals Associated with PGE Deposits

Water quality and aquatic life standards that are set by Federal and state regulatory agencies are used to evaluate the quality of our nation’s water and the health of aquatic ecosystems. These standards currently are based on hardness of the water and are determined for single metals, not for mixtures of metals that are typically found in natural systems. Metal mixtures can potentially be...
