Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Statistical and groundwater-flow models of the Fountain Creek alluvial aquifer near Colorado Springs, Colorado Statistical and groundwater-flow models of the Fountain Creek alluvial aquifer near Colorado Springs, Colorado
The U.S. Geological Survey (USGS), in cooperation with the Air Force Civil Engineering Center, created a numerical groundwater-flow model for the Fountain Creek alluvial aquifer using the finite-difference MODFLOW code with the Newton formulation solver. This numerical groundwater-flow model simulates water-budget components, groundwater-flow directions, and groundwater-flow paths of the...
Data and Code Release: Determination of Larval Sea Lamprey (Petromyzon marinus) Seasonal Sensitivity Differences to Lampricide Treatment Data and Code Release: Determination of Larval Sea Lamprey (Petromyzon marinus) Seasonal Sensitivity Differences to Lampricide Treatment
Controlling larval sea lamprey (Petromyzon marinus) in Great Lakes tributaries with 4-nitro-3-(trifluoromethyl)phenol (TFM, a pesticide) stream treatments reduces the number of spawning-phase sea lamprey, an invasive species capable of collapsing Great Lakes fisheries. An important component of stream treatments is ensuring that the proper amount of TFM is applied that will effectively...

Fish sampling data in La Grange Pool of the Illinois River during 2015 to determine largemouth bass and silver carp population size structure and size-selective largemouth bass piscivory Fish sampling data in La Grange Pool of the Illinois River during 2015 to determine largemouth bass and silver carp population size structure and size-selective largemouth bass piscivory
Dataset contains sampling information (site, location, and date of sampling) for largemouth bass and silver carp captured in La Grange Pool of the Illinois River during 2015 used to determine the population size structure of both species for analyzing size-specific feeding of largemouth bass on young-of-year and Age-1 silver carp. The dataset also contains information on fish prey items...
