Description of Work USGS scientists provide expertise, capacity and support for the implementation of Lakewide Management Plans (LaMPs) and the associated goals, objectives and targets for each of the Great Lakes, including Lake Superior. The LaMPs are critical binational groups that are important for promoting Great Lakes restoration. Specifically, LaMP efforts include compiling monitoring and research information into the Great Lakes web mapper (SiGL Mapper). The Mapper’s focus is on information that will result in recognition of areas where data are being collected, missing or sparse, and on areas where ecosystems are vulnerable.

Description of Work Predictive models have been used at beaches to improve the timeliness and accuracy of recreational water-quality assessments over the most common current approach to water-quality monitoring, which relies on culturing fecal-indicator bacteria such as Escherichia coli (E. coli.)

To support research on dispersion in river channels, a tracer dye experiment was performed on the Kootenai River in northern Idaho, September 25-27, 2017. This data release provides access to hyperspectral image acquired during the experiment and the supporting field-based measurements of reflectance and dye concentration are available through related data releases. The hyperspectral image data were acquired by Quantum Spatial Inc. (QSI) using the ITRES CASI 1500H imaging system deployed from a Cessna Caravan manned aircraft from a flying height of 1000 m above ground level. Initial geometric and radiometric data processing was performed by ITRES and yielded images with 0.5 m pixels for each of 48 spectral bands...

Description of Work The Great Lakes ecosystem has undergone major changes over the last two decades related to the invasion of Dreissenid mussels, increased water clarity, increased benthic algae and associated water quality problems. For reasons not yet entirely understood, and that have bi-national significance, water column total phosphorus has not significantly increased over the last decade but the relative percent of the more biologically available dissolved phosphorus has increased. The filtering action of Dreissenid mussels has been shown to increase concentrations of dissolved phosphorus in the water column immediately above mussel beds and this had been hypothesized as one explanation for the increase...

To support research on dispersion in river channels, a tracer dye experiment was performed on the Kootenai River in northern Idaho, September 25-27, 2017. This data release provides access to digital aerial photography acquired during the experiment and the supporting field-based measurements of reflectance and dye concentration are available through related data releases. The digital aerial photography was acquired by the U.S. Fish and Wildlife Service using a Phase One iXU180-R mapping camera deployed from a Partenavia manned aircraft from a flying height of approximately 600 m above ground level. The data product included in this release is an orthorectified mosaic in JPEG2000 (*.jp2) format produced from a...

To support research on dispersion in river channels, a tracer dye experiment was performed on the Kootenai River in northern Idaho, September 25-27, 2017. This data release provides in situ field measurements of Rhodamine WT dye concentration acquired during the experiment. A pulse consisting of 72.57 kg (160 pounds) of KEYACID™ Rhodamine WT dye that was 20% Rhodamine by weight was introduced into the Kootenai River channel from a single release point at the Kootenai Tribal Fish Hatchery over a period of 90 seconds ending at 20:10:40 PDT on 9/26/2017, which is equivalent to 04:10:40 on 9/27/2017 UTC. Information on the timing and location of the dye release is available from the KootenaiDyeReleasePoints.kmz Google...

To support research on dispersion in river channels, a tracer dye experiment was performed on the Kootenai River in northern Idaho, September 25-27, 2017. This parent data release contains links to several types of field measurements and remotely sensed data acquired during this experiment: 1) in situ measurements of Rhodamine WT dye concentration; 2) reflectance spectra and corresponding concentration measurements acquired from a boat; 3) hyperspectral image data acquired from a conventional manned aircraft; and 4) digital, three-band (RGB) aerial photographs acquired from a manned aircraft. Please refer to the individual child pages for further detail about each data set. Overall, these data were used to assess...
