BLM REA CYR 2013 Connected Small Lakes Large and small connected lakes throughout the CYR study area support a rich biodiversity of aquatic organisms and represent important foraging and breeding habitat for fish, waterfowl, and shorebirds. Additionally, lakes provide important recreational opportunities and food resources for local residents (e.g., subsistence harvest of fish and wildlife). Small and large lakes were identified based on the definition used in Arp and Jones (2009) to differentiate small (less than 0.1 sq km) from medium and large lakes (greater than 0.1 km2). Lake connections, especially for smaller lakes, can vary greatly and change throughout the open-water season, with ephemeral connections commonly occurring during high flows in...

The NHD represents the drainage network with features such as rivers, streams, canals, lakes, ponds, coastline, dams, and streamgages. The WBD represents drainage basins as enclosed areas in eight different size categories. Both datasets represent the real world at a nominal scale of 1:24,000-scale, which means that one inch of The National Map data equals 2,000 feet on the ground. To maintain mapping clarity not all water features are represented and those that are use a moderate level of detail. The NHD and WBD are digital vector datasets used by geographic information systems (GIS).... Types: Downloadable; Tags: BLM, Bureau of Land Management, CYR 2013, Central Yukon, DOI, All tags...

Stream discharge will change from surface- to groundwater-dominated flow, resulting in increased baseflows (including winter flows) and declining annual flows. Thawing permafrost along streams and rivers will decrease bank stability, which could lead to erosion and alteration of the stream channel. Shifts to deeper flow paths will result in altered stream chemistry, depending upon the soil types intersected and residence times. Observations in Alaska show that flow paths will interact with organic-rich soils and result in increased concentrations of dissolved organic carbon and nitrogen,...

Small streams are generally slow moving and freeze completely during the winter. However, some small streams may provide overwinter habitat in the form of springs and deep pools. Small stream ecosystems support extensive spawning and rearing habitat for numerous fish species in the study area. Small streams also provide important habitat for aquatic invertebrates as well as important transportation and recreational uses for local residents. Large streams are typically less productive than smaller streams due to warmer temperatures in smaller tributaries. Consequently, smaller streams are...

Watershed Boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. The intent of defining Hydrologic Units (HU) for the Watershed Boundary Dataset is to establish a base-line drainage boundary framework, accounting for all land and surface areas. At a minimum, the WBD is being delineated and georeferenced to the USGS 1:24,000 scale topographic base map meeting National Map Accuracy Standards (NMAS).

These surveys were collected over a small range of discharges using a real time kinematic global positioning system (RTK-GPS) on a motorboat traveling "on plane" along the river. These datasets were collected for equipment calibration and validation for the National Aeronautics and Space Administration’s (NASA) Surface Water and Ocean Topography (SWOT) satellite mission.

The ADEC impaired waters dataset showed all streams and lakes that did not meet State Water Quality Standards approved by EPA as of 2010. There were seven impaired streams and no impaired lakes within the Central Yukon study area. Birch, Crooked, and Goldstream creeks were listed for turbidity due to placer mining activities. Garrison Slough was listed for PCBs from military activities.

They are characterized by low temperatures, low prey densities, short open water periods, and limited overwintering habitat. Because of their depth and perennial flow, it is less likely that deep connected lakes freeze completely during winter, therefore providing important winter refuge for fish and other aquatic organisms. All lakes connected to flow lines were extracted from the USGS National Hydrography Dataset (NHD) on the North Slope, and lakes with depth greater than 1.6m were identified as deep connected lakes.

Fourteen streambank wells were installed in pairs at seven locations in August 2020 to capture the emerging groundwater from the left bank and right banks (relative to downstream-facing direction) and a synoptic sampling campaign was conducted to quantify metal contributions to the stream. A continuous, instream injection of sodium bromide (NaBr) was initiated at the head of the 5 km study reach several days prior to the synoptic sampling campaign and maintained throughout the duration of the study. Bromide concentrations...

If groundwater models can successfully simulate past conditions, they may be used to evaluate potential future pumping scenarios or climate conditions, thus providing a valuable planning tool for water-resource managers. Quantifying the groundwater-use component for a groundwater model is a vital but often challenging endeavor. This dataset includes groundwater withdrawal rates modeled for the Ozark Plateaus aquifer system (Ozark system) from 1900 to 2010 by groundwater model cell (2.6 square kilometers) for five water-use divisions: agriculture...
