Controls on the size and occurrence of pools in coarse-grained forest rivers

Publications Posted on: August 01, 2018
Controls on pool formation are examined in gravel- and cobble-bed rivers in forest mountain drainage basins of northern California, southern Oregon, and southeastern Alaska. We demonstrate that the majority of pools at our study sites are formed by flow obstructions and that pool geometry and frequency largely depend on obstruction characteristics (size, type, and frequency).

Vegetation patterns and abundances of amphibians and small mammals along small streams in a northwestern California watershed

Publications Posted on: August 01, 2018
Our goal was to describe and evaluate patterns of association between stream size and abundances of amphibians and small mammals in a northwestern California watershed. We sampled populations at 42 stream sites and eight upland sites within a 100- watershed in 1995 and 1996. Stream reaches sampled ranged from poorly defined channels that rarely flowed to 10-m-wide channels with perennial flow.

Forest management to protect Colorado’s water resources: A synthesis report to support House Bill 16-1255

Publications Posted on: December 14, 2017
The Colorado Water Plan is a collaborative framework that sets forth objectives, goals and actions by which Coloradans can collectively address current and future water challenges through feasible and innovative solutions.

Stream water quality concerns linger long after the smoke clears: Learning from Front Range wildfires

Publications Posted on: December 14, 2017
Large, high-severity wildfires alter the ecological processes that determine how watersheds retain and release nutrients and affect stream water quality. These changes usually abate a few years after a fire but recent studies indicate they may persist longer than previously expected.

Air, soil, and water resources and quality

Pages Posted on: February 06, 2017
Air, soil, and water resources and quality provide the foundation for ecosystems and ecosystem services. These publications and tools include valuable information in these areas, including spatial modeling tools and publications specific to certain regions.

A rapid response database in support of post-fire hydrological modeling

Publications Posted on: January 06, 2017
Being prepared for an emergency is important. Every year wildfires threaten homes and lives, but danger persists even after the flames are extinguished. Post-fire flooding and erosion (Figure 1) can threaten lives, property, and natural resources.

Soils [Chapter 5]

Publications Posted on: May 12, 2016
This report describes the soils of the Lost Lake, West Glacier Lake, and East Glacier Lake watersheds of GLEES and presents the methods used in conducting both the field and laboratory work. In addition, general statements about the nature of the mapping units used in making the soil maps are provided.

Meteorology [Chapter 7]

Publications Posted on: May 12, 2016
GLEES is contained within the Snowy Range Observatory. This Observatory consists of many weather stations, precipitation monitors, and stream gages scattered throughout the Snowy Range. These sites have been operated by the Wyoming Water Research Center (WWRC) since 1968. Data from the sites are available from the WWRC and were last summarized by Wesche (1982).

Introduction [Chapter 1]

Publications Posted on: May 12, 2016
Wilderness ecosystems in the United States are federally mandated and set aside by the Wilderness Act. They are managed to minimize human impact using methods that leave these systems, to the extent possible, in their natural state uninfluenced by manipulation or disruption by humans.

Hydrology [Chapter 9]

Publications Posted on: May 12, 2016
Three Parshall flumes were installed within East and West Glacier Lakes watersheds during the summer of 1987. Each Parshall flume was prefabricated fiberglass construction fitted with a hypolon liner to bring as much groundwater flow as possible to the surface so that it could be measured by passing the water through the flume.
