Flood-inundation maps of the Blue River and major tributaries in and near Kansas City, Missouri, 2023–25 Flood-inundation maps of the Blue River and major tributaries in and near Kansas City, Missouri, 2023–25
Digital flood-inundation maps for 35.5 miles of the Blue River, in and near Kansas City, Missouri, were created by the U.S. Geological Survey (USGS) in cooperation with the City of Kansas City. Maps were also developed for a combined 7.3 miles of Brush Creek (4.4 miles) and Indian Creek (2.9 miles), two primary tributaries to the Blue River in the study reach. The flood-inundation maps...
On the importance of ichthyoplankton monitoring for invasive grass carp control in the Laurentian Great Lakes On the importance of ichthyoplankton monitoring for invasive grass carp control in the Laurentian Great Lakes
Grass carp (Ctenopharyngodon idella) is an invasive herbivore observed in small numbers in the Laurentian Great Lakes since the 1980 s with records from all lakes except Lake Superior. Identification of diploid, age-1 + grass carp from the Sandusky River, a Lake Erie tributary, in 2012, prompted targeted efforts to evaluate the status of grass carp reproduction in the Lake Erie Basin. In...
Fifty years of riverine harmful algal bloom modeling: A global synthesis of approaches, challenges, and opportunities Fifty years of riverine harmful algal bloom modeling: A global synthesis of approaches, challenges, and opportunities
This systematic literature review critically examines 162 articles on harmful algal bloom (HAB) modeling in riverine systems to uncover persistent gaps, redefine critical challenges, and propose trackable opportunities to advance future modeling efforts. Articles largely focused on site-specific applications (93%) across more than 80 rivers worldwide. Most modeled systems were large...

Land application of waste to US farmland: Understanding the scope and environmental implications to aid best practices
USGS is studying how different waste materials are reused on farmland and what they might mean for people and the environment. These wastes can offer benefits, but they can also carry substances we don’t fully understand. Because little is known about what’s in these waste materials or how they move through soil and water, more information is needed. USGS research helps fill these gaps so...
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...
