Cheryl Eddy Miller
Cheryl has been with the USGS since 1989. Cheryl has studied pesticides and other water-quality issues in Wyoming's groundwater and surface water for most of her career. Her recent work has focused on groundwater/surface-water interaction, and how that interaction influences water quality. In 2013, Cheryl also became the WY-MT Water Science Center Communications Specialist.

Status: Active From Gage to Page: A Look Into How USGS Helps You Know the Flow
Knowing the streamflow of a river is important for many. For example, irrigators need to know how the water can be allocated to fields, boaters need to know if the river is safe to float, and municipalities need to know how much supply will be at their intakes.

Status: Active Creating the Rating Curve
The rating curve is a relation between stage (river level) and streamflow (discharge). Each stream channel is different and, because the stage-discharge relation is a function of the streambed material and geometry, each rating curve will be unique to that site and a particular period of time.

Status: Active Characterizing Hydrologic and Geomorphic Processes in a Spring-Fed, Cold-Desert Headwater Stream
The role of natural versus human-influenced factors in sedimentation of Littlefield Creek, a small, high-desert creek in south-central Wyoming is currently unknown. In general, there is little empirical information about both hydrologic and geomorphic processes (together described as hydrogeomorphic) in these types of streams. To develop a better understanding of hydrogeomorphic processes,...

The Blacks Fork is a stream that contributes a salinity load to the Colorado River Basin. In order to quantify the salinity load, collection of continuous streamflow and specific conductance data, and monthly sampling for total-dissolved solids will occur from April 2018 through September 2019. Calculations of monthly and annual salinity loading from the Blacks Fork will be published in 2020...

Status: Active Monitoring for Pesticides in Wyoming's Water
Wyoming's groundwater and streams are routinely monitored for pesticides. In order to balance the use of pesticides (herbicides, insecticides, and fungicides) with the protection of water resources, the Wyoming Department of Agriculture began a project to sample groundwater in 1995, in cooperation with the U.S. Geological Survey. Since the project's inception, more than 750 samples from...
