TENNESSEE VALLEY AUTHORITY
Integrated Resource Plan and Supplemental Environmental Impact Statement
The 2015 Integrated Resource Plan (IRP) provides a direction for how TVA will meet the long-term energy needs of the Tennessee Valley region. This document and the associated Supplemental Environmental Impact Statement evaluate scenarios that could unfold over the next 20 years.The IRP discusses ways that TVA can meet future electricity demand economically while supporting TVA’s equally important mandates for environmental stewardship and economic development across the Valley.

The Environmental Impact Statement focuses on the potential impacts of the various IRP strategies more closely and in greater detail than do the environmental metrics presented in this IRP. The impacts of actions to implement the IRP, such as building and operating a new generating facility, will be the subject of action- and site-specific NEPA reviews.

Frequently Asked Questions on Removal of Obsolete Dams
In support of efforts to remove obsolete dams and in response to an increase in the number of inquiries regarding EPA policies, regulations, and potential funding opportunities as they relate to removal of obsolete dams, the EPA has provided the following answers to Frequently Asked Questions.

U.S. FISH AND WILDLIFE SERVICE
Geospatial Fisheries Information Network
The GeoFIN mapper is an interactive mapping tool that allows you to view barriers to fish passage across the U.S. as well as model their removal in your watershed. It also generates profiles and reports for a given geographic area and can search the Fish and Wildlife Service's fish passage barrier database.

Migration Station
This webpage contains educational resources on fish migration. 
 

U.S. FOREST SERVICE
Aquatic Organism Passage Program
The Forest Service is recognized as a national leader in road crossing techniques that ensure aquatic organism passage, or the ability for fish and other aquatic creatures to move up or downstream under roads. The agency also assists in projects to allow for passage at irrigation diversions and small dams. Restoration work accomplished under this program occurs on forest highways, roads, and irrigation diversions in cooperation with state and county transportation agencies, landowners and a wide range of interest groups.

FishXing
This software is intended to assist engineers, hydrologists, and fish biologists in the evaluation and design of culverts for fish passage. It is free and available for download.

National Inventory and Assessment Procedure for Identifying Barriers to Aquatic Organism Passage at Road Crossings
This inventory procedure is designed to be a nationally applicable, consistent method of identifying crossings that impede passage of aquatic organisms in or along streams. It is a how-to manual for approaching answers to two questions: “How and where does the road system restrict the migration and movement of aquatic organisms; what aquatic species are affected and to what extent?”

Portable Electronic Presentations
A wealth of electronic interactive presentations on key scientific talks covering subjects such as fish passage culvert replacement, aquatic organism passage, watershed management, hydrology and geomorphology, riparian management, and more. 

Stream Simulation Culvert Design and Performance: A USFS Perspective
Aquatic organism passage at road-stream crossings has been the subject of engineering, fisheries, hydrology, and wildlife specialists’ concern for many decades. This webinar will introduce the concept of stream simulation design and provide an overview of the components of assessment, design and construction of a stream simulation design road-crossing structure.

Reservoir Sedimentation Database
This federal agency database is a work in progress and is maintained by USGS.

CUMBERLAND RIVER COMPACT
Dam Inventory, Removal and Stream Restoration
In Nashville, it may come as a surprise that a complete picture of the location and number of dams does not even exist. Working with area volunteers, we are walking streams and inventorying dams. In so doing, we’re taking the first steps towards the eventual removal of those dams that are outdated and unnecessarily impacting water quality. With your help we can begin to reconnect our waterways! This website includes a Metro Nashville Dam Inventory Map and highlights the benefits of dam removal.
