Charles F Wahl
Charles Wahl is an Ecologist with the USGS Colorado Water Science Center in Lakewood, CO.
My research focus is to understand processes that structure populations and communities in freshwater habitats with an emphasis on the role of anthropogenic disturbance. A primary goal of my investigations is to provide robust science-based knowledge that can be applied to manage, restore, and conserve natural resources. I predominantly study macroinvertebrate and fish taxa, but am also interested in freshwater macrophytes, aquatic invasive species, and the physicochemical parameters of aquatic ecosystems.

Elevation Data from Fountain Creek between Colorado Springs and the Confluence of Fountain Creek at the Arkansas River, Colorado, 2024
The U.S. Geological Survey, in cooperation with Colorado Springs Utilities, has been collecting topographic data annually since 2012 at 10 study areas along Fountain Creek, Colorado. The 10 study areas are located along Fountain Creek between Colorado Springs and the confluence of Fountain Creek and the Arkansas River in Pueblo. This data release presents topographic survey data, Light...
Datasets for Evaluation and Review of Ecology-Focused Stream Studies, Fountain Creek Basin, Colorado
These data were used to describe temporal trends in fish and invertebrate communities in the Scientific Investigators Report: Evaluation and Review of Ecology-Focused Stream Studies to Support Cooperative Monitoring, Fountain Creek Basin, Colorado. This data release consists of invertebrate data collected between 1985 and 2022, fish data collected between 2003 and 2022, and the input and...
Benthic algae community composition data from the Colorado River Basin, Colorado, from 2022-23
This dataset includes benthic algae community composition data in the Colorado River near Cameo, Colorado, U.S. Geological Survey (USGS) site number 09095500, from 2022 to 2023, and from three sites in the upper White River Basin, Colorado, in 2022. Taxonomic classification of algae species is not known well in theses rivers, and this study was conducted to record different algae species...
Invertebrate, fish, and habitat data collected within the greater Fountain Creek Basin, Colorado (version 4.0, March 2024)
Invertebrate, fish, and habitat data were collected as part of a cooperative project that began in 2002 between the U.S. Geological Survey, Colorado Springs Utilities, and Colorado Springs Engineering. Other entities have contributed to the project over the years including Colorado Parks and Wildlife. Data were primarily collected from up to 35 sites – 33 sites within the Fountain Creek...
Evaluation and review of ecology-focused stream studies to support cooperative monitoring, Fountain Creek Basin, Colorado
The U.S. Geological Survey, in cooperation with Colorado Springs Utilities and Colorado Springs Stormwater Enterprise, synthesized previous studies and evaluated recent monitoring data to understand the distribution of fish and invertebrates in the Fountain Creek Basin and documented response to streamflow, water temperature, and water quality. The goal was to identify opportunities for...
