Multimetric Index macroinvertebrate values from the Fountain Creek Basin, Colorado 2005 to 2016 These data have been collected as part of a cooperative project in between the U.S. Geological Survey, Colorado Springs Utilities, and Colorado Springs City Engineering. This project began in 2005 and has collected macroinvertebrate samples from Fountain Creek and its tributaries to monitor the biological condition of this watershed. Provided in this data release are Multimetric Index (MMI) values of aquatic macroinvertebrate assemblages using four different sampling methods. There are two subsets of these data included: (1) MMI values of macroinvertebrate data collected from 2010 to 2012 at 15 sites as part of an invertebrate sample method comparison Scientific Investigations Report (SIR) titled “Comparability...

Data were compiled from State and Federal agencies. This data table contains raw concentration data, as well as standardized concentrations corrected for differences based on sample type (i.e., tissue type), species-specific bioaccumulation rates (Table S1), and fish size (Table S2). The data were used in linear mixed effects models to estimate average mercury and selenium concentration in fish species and in fish assemblages, including fish total length (cm), sampling location (Sub basin name and GPS coordinates), and sampling year (Figures 2,3, and 4...

We used grass carp that were implanted with acoustic transmitters. The position data was generated in Fathom Position from receivers that composed several VEMCO Positioning Systems (VPS). We also queried the Great Lakes Acoustic Telemetry Observation Network (GLATOS) to obtain non-VPS position detections from receivers made from multiple projects across Lake Erie and associated tributaries. Sampling data was downloaded from the grass carp capture database hosted on ArcGIS Online These data contain information such as location of event, time gears were deployed and retrieved, and number of grass carp caught.

The detection data also includes information about the receivers that recorded the detection of acoustic telemetry tags implanted in walleye and grass carp from from 2014 to 2021. Receiver attributes include location and deployment history of each receiver. Detections indicate where and when an individual fish implanted with a unique acoustic telemetry tag was recorded by a receiver. The attributes for each individual fish implanted with a tag and detected by a receiver include biological characteristics, tag details, and post-tagging release location.

The powered vessels overtook the USVs in Lakes Huron and Michigan to study fish avoidance of survey vessels during traditional acoustic surveys. The water column was divided into three depth groups (epilimnion, metalimnion, hypolimnion) for analysis. Each drone transect was binned into 30-sec intervals and measured hydroacoustic values were averaged in this region. To compare vessels and drones, parallel overtakes (overtakes where vessel and drone followed the same path) which were ~2 km long, were measured by both platforms and the differences between acoustic measures compared.

Selenium bioaccumulation in aquatic organisms is primarily the result of trophic transfer through food webs and is poorly predicted by dissolved concentrations in freshwater bodies. To better understand the hydrologic and biological dynamics that control selenium accumulation into fishes of the Lower Gunnison River Basin (Colorado), ecosystem scale selenium accumulation models were developed from data collected between June 2015 and October 2016.

In the Southern Rocky Mountains, greenback cutthroat trout (Oncorhynchus clarkii stomias; GBCT) are listed as threatened under the ESA, and few populations remain, in part because of the invasion of nonnative fishes (for example, brook trout, Salvelinus fontinalis). In an effort to restore GBCT to their native range, chemical treatments (piscicides) are often used as a tool to remove nonnative fishes prior to reintroducing native fish. However, the influence of the piscicides on nontarget organisms, such... Categories: Data; Tags: Aquatic Biology, Browns Lake, Colorado, Dry Gulch, Ecology, All tags...

Data was primarily collected from 22 sites within the Pictured Rocks National Lakeshore. The number of sites sampled each year as well as the types of data collected and sampling methods varied during each visit. This data release includes data collected between 2021 and 2022.
