This story map depicts the initial point of the Gila and Salt River meridian in Arizona. There are two georeferenced plats along with a description of the significance. The Gila and Salt River initial point was set in 1851 by John R. Bartlett, originally to mark the boundary of the United States and Mexico under the treaty with Mexico of Guadalupe Hidalgo at the junction of the Gila and Salt Rivers. It was re-monumented in 1984 and again in 2006.

As part of the ongoing effort to engage the public in the General Land Office and the BLM, and to increase interest in historic land records, the GLO Record of the Week Story Map Project (ROWSMP) was created. What was once just infrequent emails with interesting records and stories to BLM employees, the ROWSMP wants to further engagement by improving the regularity of publication and increasing the amount of information presented with an emphasis on interactivity while also broadening the audience to the public. This story map is a special edition of the regular GLO ROTW Story Map. This webapp focuses on Halloween and presents GLO records that fit within the theme.

This project will create a targeted and easily understandable guide to tools that support landscape-level planning in the face of climate change for NPLCC partners. The guide will build on previous NPLCC research on decision support needs with an emphasis on tools currently in use in the region. A survey of NPLCC partners will discover who is currently using or planning to use tools in the region, tools they are using, how well these tools are meeting their needs, and regional and outside experts engaged in tool use. Additional tools research will provide information on tools not currently in use in the region that could also provide needed functionality.

In large river ecosystems, the timing, extent, duration and frequency of floodplain inundation greatly affect the quality of fish and wildlife habitat and the supply of important ecosystem goods and services. Seasonal high flows provide connectivity from the river to the floodplain, and seasonal inundation of the floodplain governs ecosystem structure and function. River regulation and other forms of hydrologic alteration have altered the connectivity of many rivers with their adjacent floodplain – impacting the function of wetlands on the floodplain and in turn, impacting the mainstem river function. Conservation and management of remaining floodplain resources can be improved through a better understanding of...

The Alabama Department of Transportation (ALDOT) and the U.S. Geological Survey (USGS) studied several sites in the northern East Gulf Coastal Plain of Alabama to investigate effects of newly installed box culverts on the natural conditions of the streams they are traversing (Pugh and Gill, 2021). Data collection for the study spanned approximately 10 years and included before-, during-, and after-construction phases of box culvert installations at selected stream sites. The objectives of the project were to (1) assess the degree and extent of changes in geomorphic conditions, suspended-sediment concentrations, turbidity, and benthic macroinvertebrate populations at selected small streams following box culvert installation...

The Crystal Darter (Crystallaria asprella) requires large, clear-water streams with clean sand and gravel bottoms and moderate to swift currents. It is intolerant of siltation and other forms of pollution from various land use practices. Direct habitat degradation from damming, channelization, and dredging has also reduced habitat for this species. Remaining populations have become isolated from one another by dams and impoundments. The Mississippi River most likely no longer serves as a usable corridor for the Crystal Darter because of the silt load. The isolated local populations are then vulnerable to single destructive events such as toxic chemical spills.

Partnerships - Atlantic Coastal Fish Habitat Partnership, Eastern Brook Trout Joint Venture, Reservoir Fisheries Habitat Partnership, and Southeast Aquatic Resources Partnership Removed four barriers that opened access to six mile of streams and restored 21 miles of streams to improve habitat for Eastern Brook Trout and other fish species. A shoreline restoration demonstration area was constructed near the U.S. Army Corps of Engineers Visitors Center in North Carolina. Native vegetation was used to stabilize 175’ of shoreline to be used as a showcase for other lakeshore property owners. Planted 0.2 acres of tidal marsh and installed 0.1 acres of oyster reefs in Stump Sound, North Carolina. Also planted 0.15 acres...

Available data for the American Eel (Anguilla rostrata) indicate that, overall, there have been declines in recruitment, population, and escapement during three generations (36 years). A recent report indicated that barriers to migration (dams and weirs), passage through turbines at hydropower dams, habitat degradation or loss, and overharvest were likely the greatest threats by humans across the species’ range. Although eels are able to ascend many smaller barriers, recent studies have documented a tenfold reduction in eel density above each potentially passable barrier. For example, the number of juvenile eels migrating to Lake Ontario passing over hydropower dams fell from 935,000 in 1985 to approximately 8,000...

The habitats of the Southeast Atlantic states range from the mountains and uplands in the Blue Ridge and Piedmont areas in the western portion of this region to the Southeastern and Coastal Plains. Fish habitats in the higher elevation regions are typically fast-moving, clear, coldwater streams originating from seeps and springs, while warmwater rivers of the plains carry more organic material and sediment. This diversity of habitats along a very long period of stable geologic activity produces one of the most diverse assemblages of aquatic species in the nation. The Altamaha, Chattahoochee, Flint, Savannah, Catawba, Pee Dee, Broad, and Neuse are major rivers of the region. There are a large number of dams on waterways...

Partnership - Hawaii Fish Habitat Partnership Anchialine pools represent an inland waterbody type that is widespread but threatened throughout the Hawaiian Islands and is a key habitat type of concern to the Hawaii Fish Habitat Partnership. Anchialine pools, also known as fishponds in Hawaii, are near the coast and are land-locked bodies of water that have connections both to the sea, typically by high tides, as well as to local freshwater. These systems have been used for thousands of years for fish production by Native Hawaiians. The majority of remaining fishpond pools are located on the Kona coast and southern coastlines of the Big Island, the southeast coast of Maui, and on several small and widely separated...

State-wide data on fish populations were limited in Alaska for use in this assessment, as was a detailed spatial (mapping) framework that fully characterizes watersheds throughout the state at the time this assessment was conducted. Because of these factors, we modified our assessment methods to account for these limitations. Twenty-one landscape disturbance variables were assembled from medium-sized watersheds throughout the state (i.e., 12-digit hydrologic unit code watersheds). Variables were then assigned to one of six categories based on their disturbances to stream habitats. Categories include: urban land use, agricultural land use, point source pollution and water quality, barriers to fish movement, human...

The Waccamaw Silverside (Menidia extensa) has a very limited distribution confined to Lake Waccamaw in North Carolina, a lake with neutral pH levels from underlying limestone formations in an area of acidic natural waters. This species is found in large schools and often over dark-colored substrates. Its limited habitat is threatened by nutrient loading caused by the runoff of organic matter and agricultural chemicals.

The Ironcolor Shiner (Notropis chalybaeus) is found in deep pool areas of creeks and small rivers and is often associated with aquatic vegetation. This species needs clear sandy areas for spawning. Populations of Ironcolor Shiner are in decline due to increased turbidity, siltation, and pollution.
