Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Debris-flow and Flood Video Files, Chalk Cliffs, Colorado, USA, 2019 Debris-flow and Flood Video Files, Chalk Cliffs, Colorado, USA, 2019
Chalk Cliffs, located 8 miles southwest of Buena Vista, Colorado, is a natural laboratory for research on runoff-initiated debris flows (Coe et al., 2010). In 2019, there were two monitoring stations operating at Chalk Cliffs. The Upper Station drains an area of 0.06 km2 and was used to monitor flow properties and triggering conditions in the headwaters of the study area. It was equipped...
Geomorphic Monitoring Associated with the 2020 Pilchuck Dam Removal Geomorphic Monitoring Associated with the 2020 Pilchuck Dam Removal
The Pilchuck Dam, a low-head dam previously used for water-supply diversion in Snohomish County, Washington was removed from the Pilchuck River in the summer of 2020 after having blocked upstream fish migration for over a century. That removal effort was led by the Tulalip Indian Tribe; the USGS, in collaboration with the tribe, monitored sediment evacuation from the impoundment and...
Handling times: tagging vs photos, Boreal toads in WY/CO 2020 Handling times: tagging vs photos, Boreal toads in WY/CO 2020
Individual identification is required for investigations that examine population-level changes (e.g., decreased survival, increased disease prevalence) and the mechanisms associated with these changes in wild populations. Such identification generally requires the application of a unique mark, or the documentation of characteristics unique to each individual animal. Marking strategies...
Assessing the Status and Trends of Seabirds and Forage Fish in Lower Cook Inlet, Alaska Assessing the Status and Trends of Seabirds and Forage Fish in Lower Cook Inlet, Alaska
This data release is composed of seven datasets regarding colonial seabirds and forage fish at two seabird nesting colonies on Gull and Chisik Islands in lower Cook Inlet, Alaska. These data were collected to detect changes in the breeding population of Black-legged Kittiwakes and Common Murres on two nesting colonies in lower Cook Inlet and to compare those counts to baseline counts...
Multi-objective Modeling as a Decision-support Tool for Feral Horse Management Multi-objective Modeling as a Decision-support Tool for Feral Horse Management
Decisions related to controversial problems in natural resource management receive the greatest support when they account for multiple objectives of stakeholders in a structured and transparent fashion. In the United States, management of feral horses (Equus caballus) is a controversial multi-objective problem because disparate stakeholder groups have varying objectives and opinions...
Assessing the Northeastern Gulf of Mexico Microtidal Wetland System Change in the Apalachicola-Big-Bend Region Under Sea-Level-Rise: Model Inputs and Outputs Assessing the Northeastern Gulf of Mexico Microtidal Wetland System Change in the Apalachicola-Big-Bend Region Under Sea-Level-Rise: Model Inputs and Outputs
Using the Hydrodynamic-Marsh Equilibrium Model (Hydro-MEM), the wetlands system within the Apalachicola-Big-Bend region of Florida (FL) (Fig. 1) was assessed using three sea-level rise scenarios of intermediate-low (50 centimeters [cm] by 2100), intermediate (1 meter [m] by 2100), and intermediate-high (1.5 m by 2100) from the National Oceanic and Atmospheric Administration (NOAA).
