A Point Sampler Used at the Bonnet Carré Spillway

Detailed Description

A point sampler for measuring sediment. It has tail fins to orient the sampler so that the intake nozzle in the head points directly into the approaching flow. The sampler head is hinged to provide access to the pint or quart bottle sample container located in a cavity in the sampler body. Once the sample container is filled, the sampler is raised, and the water and sediment are taken to the lab for analysis. Learn more about the point sampler here:

In late 2015/early 2016 unusually large rainfall in the Upper Mississippi River Valley led to significant flooding in Arkansas, Illinois, Louisiana, Mississippi, Missouri, and Tennessee. USGS crews responded to the flooding by collecting streamflow and water quality information and providing it to emergency responders.
