Using a portable flume to measure streamflow on a small stream

Preparing to measure water level at Groundwater Streamgage

For the first time since it was opened in 1984, water has stopped flowing through the Great Salt Lake causeway breach, an area that allows water to travel between the southern and northern parts of the lake.

A gage to measure lake water levels stands dry in the lake bed of the Great Salt Lake. For the first time since it was opened in 1984, water has stopped flowing through the Great Salt Lake causeway breach, an area that allows water to travel between the southern and northern parts of the lake.

Determining aboveground biomass of sagebrush, grasses, and forbs is important for estimating fuel loads, measuring carbon storage, and assessing habitat quality in shrublands. Remote sensing may offer a more efficient alternative to common, labor intensive methods of measuring aboveground biomass that are difficult to apply across large areas.
