Precipitation-based flood-inundation maps for the East Fork Little Blue River and tributaries at Lee’s Summit, Missouri, 2024 Precipitation-based flood-inundation maps for the East Fork Little Blue River and tributaries at Lee’s Summit, Missouri, 2024
The U.S. Geological Survey, in cooperation with the City of Lee’s Summit, Missouri, assessed flooding of the East Fork Little Blue River and tributaries for varying precipitation magnitudes and durations, varying antecedent runoff conditions, and projected climate-change conditions. The precipitation scenarios were used to develop a library of flood-inundation maps for a 2.95-mile reach...
Drift and dispersion of silver carp (Hypophthalmichthys molitrix) eggs and larvae for hypothetical spawning scenarios in the Upper Mississippi River Drift and dispersion of silver carp (Hypophthalmichthys molitrix) eggs and larvae for hypothetical spawning scenarios in the Upper Mississippi River
Invasive carp pose ecological and economic risks to North American freshwater systems. This study uses the Fluvial Egg Drift Simulator to model the drift of invasive silver carp (Hypophthalmichthys molitrix) eggs and larvae after hypothetical spawning in Pools 1–10 of the Upper Mississippi River. Although adult invasive carps have been detected in this region, no reproduction has been...
Spatially consistent but temporally divergent changes in nitrate and phosphorus loads and yields in Illinois watersheds, 1997–2022 Spatially consistent but temporally divergent changes in nitrate and phosphorus loads and yields in Illinois watersheds, 1997–2022
Illinois contributes substantial nutrient loads to the Gulf of America, warranting watershed-scale assessment. This study estimated nitrate-nitrogen (nitrate-N) and total phosphorus (TP) loads and yields for 49 Illinois 8-digit hydrologic unit code (HUC8) watersheds draining to the Mississippi River Basin from 1997–2022, comparing recent (2018–2022) to baseline (1997–2011) conditions...

Real-Time Fish Telemetry
The USGS real-time fish telemetry network is operated in collaboration with partner agencies including the U.S. Fish and Wildlife Service, the U.S. Army Corps of Engineers, and the States of Illinois, Ohio, and Michigan. The primary function of this network is to monitor the movement of invasive carp in priority rivers. When invasive carp are detected at one of our receivers, subscribers at...

From Stream to Spider: How PFAS Move Through Aquatic and Terrestrial Food Webs
Per- and polyfluoroalkyl substances (PFAS) are persistent synthetic chemicals that accumulate in the environment and living organisms. A USGS study examined how different PFAS compounds move through a stream ecosystem and are transferred from aquatic to terrestrial food webs. The findings documented that not all PFAS behave the same once they enter the environment, leading to differences in...
