Fishes of Missouri River, chute, and flood plain habitats: Chapter 4 in Initial biotic survey of Lisbon Bottom, Big Muddy National Fish and Wildlife Refuge Fishes of Missouri River, chute, and flood plain habitats: Chapter 4 in Initial biotic survey of Lisbon Bottom, Big Muddy National Fish and Wildlife Refuge
The Lisbon Bottom Unit of the Big Muddy National Fish and Wildlife Refuge (Refuge) is approximately 2,200 acres and is the first complete unit of the Refuge. Primary objectives of the Refuge are to create and restore diverse riverine aquatic habitats and reconnect the Missouri River to its flood plain where feasible. Management seeks to accomplish these objectives by encouraging natural...

Development of a 14-digit Hydrologic Unit Code Numbering System for South Carolina Development of a 14-digit Hydrologic Unit Code Numbering System for South Carolina
A Hydrologic Unit Map showing the cataloging units, watersheds, and subwatersheds of South Carolina has been developed by the U.S. Geological Survey in cooperation with the South Carolina Department of Health and Environmental Control, funded through a U.S. Environmental Protection Agency 319 Grant, and the U.S. Department of Agriculture, Natural Resources Conservation Service. These...

Embryotoxicity of Great Lakes lake trout extracts to developing rainbow trout Embryotoxicity of Great Lakes lake trout extracts to developing rainbow trout
Planar halogenated hydrocarbons (PHHs), such as polychlorinated dibenzo-p-dioxins, dibenzofurans, and biphenyls are present in aquatic systems, and are known to produce adverse effects in fish. This study investigated the embryotoxicity of PHH mixtures through the nanoinjection of environmental extracts into newly fertilized eggs from two strains of rainbow trout. Organic extracts were...

Stormwater runoff for selected watersheds in the Edwards Aquifer recharge zone, Bexar County, Texas, 1996-98 Stormwater runoff for selected watersheds in the Edwards Aquifer recharge zone, Bexar County, Texas, 1996-98
The Edwards aquifer is one of the most productive carbonate aquifers in the Nation. The dissolution-modified, faulted limestone aquifer is the sole source of public water supply for San Antonio, Texas (fig. 1) and is the major source of water for Bexar County. In addition to providing public water supply to more than 1 million people, the Edwards aquifer supplies large quantities of...

Texas Texas
In 1997, the Texas Legislature passed a comprehensive revision to the Texas Water Code. This legislation (Senate Bill 1) changed water planning in Texas from a statewide to a regional activity. By September 2001, the 16 regions created by Senate Bill 1 must produce water plans to address their water needs during drought-of-record conditions, and must identify water-management strategies...

The relationship between species density and community biomass in grazed and ungrazed coastal meadows The relationship between species density and community biomass in grazed and ungrazed coastal meadows
Previous studies have indicated that the relationship between community biomass and species density can be represented by a multivariate model in which abiotic variables influence species density both through effects on biomass and through effects on the species pool. In this paper, we use data from grazed and ungrazed coastal meadows in Finland to evaluate and extend this general...

Physical setting: Chapter 1 in Initial biotic survey of Lisbon Bottom, Big Muddy National Fish and Wildlife Refuge Physical setting: Chapter 1 in Initial biotic survey of Lisbon Bottom, Big Muddy National Fish and Wildlife Refuge
Lisbon Bottom consists of approximately 875 ha of river bottom along the Missouri River in Howard County, Missouri, from approximately river mile (RM) 213 to RM 219. As used in this report, the Lisbon Bottom area also includes the main channel of the Missouri River adjacent to the Lisbon Bottom and portions of the adjacent flood plain in Saline County, Missouri.
