Streamflow Statistics for Unregulated and Regulated Conditions for Selected Locations on the Yellowstone, Tongue, Powder, and Bighorn Rivers, Montana

Major floods in 1996-1997 on the Yellowstone River intensified public debate over the effects of human activities on the Yellowstone River. The Yellowstone River Conservation District Council partnered with the U.S. Army Corps of Engineers to conduct a cumulative-effects study on the Yellowstone. For that study, the USGS calculated streamflow statistics for unregulated (no development) and...

A review of timing accuracy across the Global Seismographic Network

The accuracy of timing across a seismic network is important for locating earthquakes as well as studies that use phase‐arrival information (e.g., tomography). The Global Seismographic Network (GSN) was designed with the goal of having reported timing be better than 10 ms. In this work, we provide a brief overview of how timing is kept across...
