On October 1, 2021, the U.S. Geological Survey Colorado River streamflow gaging site (USGS 09380000) at Lees Ferry will mark its 100-year anniversary of recording continuous streamflow data. As the gage of record for the apportionment of the Colorado River between the Upper and Lower Colorado River basins, the Lees Ferry site is arguably one of the most important

Harmonized Landsat and Sentinel-2 (HLS) data are here!

The LP DAAC and the HLS Science Team are pleased to announce the release of Harmonized Landsat and Sentinel-2 (HLS) version 2.0 surface reflectance products. HLS data are composed of observations from Landsat 8 and Sentinel-2 and provide a set of seamless data products that can be utilized as if all

RestoreNet is partnering with the Gornish lab at the University of Arizona to better understand how a plant’s source location (provenance) influences its performance in a restoration setting. This greenhouse experiment will be conducted by PhD student, Sierra Lauman. Sierra will use locally collected and commercially purchased seeds of eight commonly used restoration

The United States is developing renewable energy resources, especially solar, at a rapid rate. Although renewable energy development is widely perceived by the public as “green technology,” construction, operation, maintenance, and eventual decommissioning of facilities all have known and potential negative impacts to natural resources, including plant communities and

Connecting powerline rights-of-way vegetation management to improve pollinator habitat. A USGS RAMPS technician samples pollinating insects along the Salt River Project powerline that crosses through Apache-Sitgreaves and Tonto National Forests. This fall, baseline plots were established in areas that will be treated with mechanical and chemical vegetation management

For five days in March of 2021, the Glen Canyon Dam released a historically low flow of 4,000 cubic feet per second into the Colorado River. The USGS took this opportunity to collect data in an attempt to verify the measurements being reported by the Lee’s Ferry gaging station, which showed a discrepancy between the amount of water being released at the dam and the water
