These data are providing constraints...The National Water Information System (NWIS) web application provides access to real-time and historical surface-water, groundwater, water-quality, and water-use data collected at approximately 1.5 million sites across all 50 states.Grassland bird populations have declined more than any other group of birds in North America and are of conservation concern to state and federal agencies. For example, it takes 20 quads to cover all of Richland County. The mapper displays model inputs such as aquifer recharge and hydraulic conductivity; outputs including water-table elevations, groundwater-flow directions, and stream baseflows; and the results of an analysis evaluating potential monitoring well locations.During both regulatory and routine surveillance sampling of baitfish from the states of Illinois, Minnesota, Montana, and Wisconsin, USA, isolates (n = 20) of a previously unknown picornavirus were obtained from kidney/spleen or entire viscera of fathead minnows (Pimephales promelas) and brassy minnows (Hybognathus hankinsoni). United States.

MMSD Watercourse Corridor Study ecological assessments evaluate water quality over time by pairing community assessments of aquatic organisms with chemical assessments using passive samplers.We use core descriptions and portable X-ray fluorescence analyses to identify lithofacies and stratigraphic surfaces for the Mesoproterozoic Nonesuch Formation within the Ashland syncline, Wisconsin.

Nutrient data collected from 64...The USGS partnered with the Minnesota Department of Natural Resources to collect hydraulic and water chemistry data in the lower St. Croix River for development of a model that predicts the probability of successful egg hatching and survival of juvenile invasive carp over a range of water temperature and streamflow conditions.This map shows the provinces assessed by the USGS for undiscovered oil and gas resources.The public is invited to attend a free, family-friendly open house at a local U.S. Geological Survey center for ecology research on Saturday, September 9.Land cover and land use (LC/LU), climate, and biogeochemical processing are significant drivers of water quality in streams and rivers over broad scales of space and time. To address data needs for determining the status of goshawk populations, Hargis and Woodbridge (2006) developed a bioregional monitoring protocol based on estimating occupancy.
