Moored All-Season Vertical Temperature Arrays in Lakes on Kodiak, Togiak, and Alaska Peninsula/Becharof National Wildlife Refuges The primary purpose of this project is to acquire long-term data series ontemperature of selected lakes to support management of nursery habitat of lakerearingjuvenile sockeye salmon (Oncorhynchus nerka) in relation to climatechange. We adopted protocol developed by the National Park Service (NPS) toestablish moored all-season vertical temperature monitoring arrays in eight lakesof Kodiak, Togiak, and Alaska Peninsula/Becharof National Wildlife Refuges(NWR) in summer and fall 2011. We recorded lake temperature at a resolution of0.02°C on an hourly basis at various depth strata between lake surfaces and lakebottoms. Monitoring sites were visited annually or biannially to extract data andto service monitoring equipment....

The capacity and surface-area tables describe the relation between the elevation of the water surface and the volume of water that can be impounded at each given water-surface elevation. The capacity and surface area of Grand Lake O’ the Cherokees were computed from a Triangular Irregular Network (TIN) surface created in Global Mapper Version 21.0.1.

Freshwater ecoregions provide a global biogeographic regionalization of the Earth's freshwater biodiversity. These units are distinguished by patterns of native fish distribution resulting from large-scale geoclimatic processes and evolutionary history. The freshwater ecoregion boundaries generally, though not always, correspond with those of watersheds. Within individual ecoregions there will be turnover of species, such as when moving up or down a river system, but taken as a whole an ecoregion will typically have a distinct evolutionary history and/or suite of ecological processes (Abell et al. 2008).

We examined all connected stream networks in the Northeast and Mid-Atlantic for seven characteristics correlated with resilience. These included four physical properties (network length, number of size classes, number of gradients classes and number of temperature classes), and three condition characteristics (risk of hydrologic alterations, natural cover in the floodplain, and amount of impervious surface in the watershed).

Climate models project even drier summers in the future. This could pose a problem for migrating fish that must be able to move back and forth from breeding and summer feeding areas to scarce overwintering sites. This work uses the best available long-term hydrologic data set for the North Slope (in the upper Kuparuk River watershed) to develop a model to assess the vulnerability of stream systems to periodic drought, and the vulnerability of migrating fish to a loss of stream connectivity.

These fish migrate to spawning grounds just after breakup in the spring, then migrate to feeding sites in early summer, and finally in the fall migrate back to their overwintering sites. The Kuparuk River is a perennial stream originating in the northern foothills of the Brooks Range on the North Slope of Alaska. Sections of the Kuparuk are periodically intermittent in that, during low flows in the system, these channel reaches appear dry.
