Authorized structures include staff gages, tide and current gages, meteorological stations, water recording devices, and biological observation tools. It also covers devices for water quality testing and improvement, provided they are used for data collection purposes.\n\nThe permit allows for the construction of small weirs and flumes primarily intended to record water quantity and velocity. However, these specific structures are subject to a strict volume limit: the discharge of dredged or fill material cannot exceed 25 cubic yards. All devices and associated structures, such as foundations and anchors, must be removed and the site restored to its original elevation once the data collection period ends.","During the public comment period, some commenters recommended that the Corps require a Pre-Construction Notification for all weirs and flumes to prevent harmful sedimentation and flow impacts. Others suggested modifying the permit to strictly prohibit any device that cannot be entirely removed .\n\nThe Corps declined to add a PCN requirement for weirs and flumes, noting that the 25-cubic-yard limit and general conditions regarding aquatic life movement and erosion control are sufficient to minimize impacts. They also maintained the 'maximum extent practicable' standard for device removal, explaining that in some cases, full removal might cause more environmental damage than leaving a portion of a structure, such as a buried piling, in place.","This permit is typically used by scientific researchers, environmental consultants, and government agencies involved in hydrology, meteorology, or aquatic biology.
