- Description
- This dataset features the NetMap processed streamlines for Prince of Wales Island, providing a comprehensive representation of the island's stream network. The streamlines are derived from advanced geospatial analyses, offering critical insights into the hydrological landscape of this ecologically rich region. Regionally derived intrinsic potential models have been developed and summarized, highlighting the potential habitat quality for anadromous fish species. These models assess the upstream effects of various geomorphic and hydrological attributes, providing valuable information for habitat restoration and conservation efforts. This layer is intended for use by resource managers, conservationists, and researchers involved in aquatic habitat assessments, restoration planning, and watershed management. It serves as a vital tool for identifying priority areas for conservation and understanding the ecological dynamics of Prince of Wales Island's stream systems.

There is no guarantee or warranty concerning the accuracy of the data. Users should be aware that changes may have occurred since this data set was created and that some parts of this data may no longer represent actual conditions. Users should not use this data for critical applications without a full awareness of its limitations. Regardless of the types of predictions made by the TerrainWorks/NetMap software, and including any and all applications by anyone, no warranties, express or implied, are made and in fact are disclaimed. Applying shallow landslide, gully, surface erosion and debris flow models and predictions requires careful consideration of other factors including the applicability of any models to diverse landscapes (e.g., is model appropriate), other important factors such as climate, vegetation characteristics, soils, land-use activities, wildfire history, and landslide history (at any particular site and in the larger landscape). Model users should have expertise in geotechnical disciplines in order to appropriately interpret landslide and debris flow hazards. Using models to predict erosion is never a substitute for field work and analysis. Models only provide an approximation of on the ground conditions. It is recommended to use both modeling, to provide a coarse level screening of erosion potential, followed up by field verification of model parameters (such as slope) and actual erosion conditions. The boundaries between erosion potential map elements predicted by NetMap/TerrainWorks software (e.g., digital landscapes and analysis tools) are approximate. Actual boundaries between mapping elements in any specific location need to be determined in the field, on site. In addition, not all small-scale landslide-prone features will be mapped and other features may be encountered during field inspections. Moreover, the sediment delivery potential (to streams and to other identified locations) of predicted erosion features, as well as any other erosion-prone landforms, should be verified in the field, on site. The erosion predictions in the TerrainWorks/NetMap software are based on scientific information. However, any erosion prediction will contain inaccuracies and limitations because of 1) the relatively short and unique history of storms that triggered erosion and that are used to create the science (e.g., longer and different time periods and larger storms may yield different scientific results, models and understanding) and 2) the incomplete scientific understanding of all erosion mechanisms. For these reasons, all erosion predictions made by the TerrainWorks/NetMap software will not completely identify all of the potentially erodible areas. Regardless of the types of predictions made by the TerrainWorks/NetMap software, and including any and all applications by anyone, no warranties, express or implied, are made and in fact are disclaimed.
