Have You Ever Wondered What A New Concrete Stilling Well [stream gauge] Looked Like?
--
H/T Roy Socolow, USGS
"While doing research on the USGS stream gaging program for a local presentation, [he] found this beautiful image of a classic stilling well from the Kentucky archives. Intakes and valve stems in perfect condition, hand pump and flush tank ready to fill, no kerosene or funky well water smell, and the clock weights on the Stevens recorder have plenty of travel room. Makes them] think of the good old days climbing down well ladders to “muck out” wells. Many of these “tanks” of instrument shelters still exist with either working intakes or as converted bubble gages. Many others have been decommissioned due to safety issues (falling or confined space hazards). Thanks to the men of the #CCC and #WPA..."

Estimating Increased Transient Water Storage With Increases In Beaver Dam Activity
--
https://doi.org/10.3390/w16111515 <-- shared paper
--
“Dam building by beaver (Castor spp.) slows water movement through montane valleys, increasing transient water storage and the diversity of residence times. In some cases, water storage created by beaver dam construction is correlated to changes in streamflow magnitude and timing. However, the total amount of additional surface and groundwater storage that beaver dams may create (and, thus, their maximum potential impact on streamflow) has not been contextualized in the water balance of larger river basins..."

USGS Water Data Centers May Soon Close, Threatening States’ Water Management

"Across the country, the data collected at stream gauges managed by the U.S. Geological Survey are used to implement drought measures when streamflows are low, alert local authorities of floods, help administer water to users on rivers and issue pollution discharge permits required by the Clean Water Act for communities across the country."

But more than two dozen USGS Water Science Centers that house the employees and equipment to manage those gauges and equipment will soon have their leases terminated after being targeted by the Department of Government Efficiency. Data collected by the centers inform studies of the condition of the country’s water resources and shape local and state water management plans.
