File Acid Mine Drainage and Effects on Fish Health and Ecology: A Review
Acid rock drainage (ARD) is produced by the oxidation of sulfide minerals, chiefly iron pyrite or iron disulfide (FeS2). This is a natural chemical reaction which can proceed when minerals are exposed to air and water. Acidic drainage is found around the world both as a result of naturally occurring processes and activities associated with land disturbances, such as highway construction and mining where acid-forming minerals are exposed at the surface of the earth. These acidic conditions can cause metals in geologic materials to dissolve, which can lead to impairment of water quality when acidic and used by terrestrial or aquatic organisms. metal laden discharges enter waters.

Project Altamaha River Flathead Project: More than One Way to Skin a Cat: Controlling the spread of invasive flathead catfish through research, outreach and education
The Altamaha River Watershed Conservation Action Plan cites invasive species as one of the six highest ranked threats. One of the invasive species thriving in portions of the watershed is the flathead catfish, which cause environmental harm, threaten native species, and can change the recreational value of an area for anglers. User groups (general public, children, anglers, commercial fishermen) as well as watershed managers must work together to control a population by size or area of infestation.

Brook Trout Habitat Improvements to McIntosh Brook, Allegany State Park, New York
Allegheny State Park contains the most intact and widespread distribution of wild brook trout streams in western New York. Brook trout growth and abundance in McIntosh Creek are limited by a lack of large woody debris and deep water pools during summer low flow conditions. This project will add large woody debris to enhance habitat structure and deep water pools to increase wild brook trout growth and abundance, and improve the recreational fishery. Pre- and post-enhancement monitoring will be conducted and used to demonstrate this simple and low cost approach to improve brook trout habitat.

Brook Trout Restoration Lynn Camp Prong, Great Smokey Mountain National Park, Tennessee
The purpose of the project is to continue to restore the Southern Appalachian brook trout to a larger lower elevation stream within its historic range in the Great Smoky Mountain National Park. To date, park biologists have restored 17.2 miles of historic range for brook trout. The successful completion of this project will add 8 miles to this total.

Catawissa Creek AMD Restoration, Pennsylvania
An historic mine water discharge tunnel draining a deep mine is contributing 80 percent of the pollution load of acid and aluminum impairing Catawissa Creek. The objective of this project is to complete a limestone mitigation project that will treat the source of AMD and restore the pH regime of the stream. The project will enable the return of extirpated brook trout to 36 miles of the main stem of the Catawissa Creek. It will also reconnect the entire watershed including more than two dozen tributaries, many of which are not impaired and have healthy brook trout populations.
