No sooner had the EPA established the Superfund program in 1980 to clean up the nation’s toxic waste dumps and other abandoned hazardous waste sites, than a little Montana town found itself topping the new program’s National Priority List. Milltown, a place too small to warrant a listing in the U.S. Census, sat alongside a modest hydroelectric dam at the confluence of the Clark Fork and Blackfoot Rivers. For three-quarters of a century, arsenic-laced waste from some of the world’s largest copper-mining operations had accumulated behind the dam. Soon, Milltown became the site of Superfund’s first dam removal and watershed restoration, marking a turning point in U.S. environmental history. The story of this dramatic shift is the tale of individuals rallying to reclaim a place they valued beyond its utility. In Restoring the Shining Waters, David Brooks gives an intimate account of how local citizens—homeowners, university scientists, county health officials, grassroots environmentalists, business leaders, and thousands of engaged residents—brought about the removal of Milltown Dam. Interviews with townspeople, outside environmentalists, mining executives, and federal officials reveal how the everyday actions of individuals got the dam removed and, in the process, pushed Superfund to allow more public participation in decision making and to emphasize restoration over containment of polluted environments. A federal program designed to deal with the toxic legacies of industrialization thus became a starting point for restoring America’s most damaged environments, largely through the efforts of local communities. With curiosity, conviction, and a strong sense of place, the small town of Milltown helped restore an iconic western river valley—and in doing so, shaped the history of Superfund and modern environmentalism.

Presents a literature review summarizing the spawning and rearing habitat requirements of bull trout, Salvelinus confluentus, during the stream phases of the fish's life history. The literature search focused primarily on literature that is difficult to obtain for most fisheries biologists. The data from 42 articles that contained information pertaining to rearing and spawning habitat use are summarized in a tabular format. The habitat variables summarized for rearing bull trout are: water temperature, water depth, water velocity, cover, and substrate. Measures of habitat use that are summarized are: water depth, cover water velocity, and substrate.

Loss of connectivity among populations and interactions with nonnative species can negatively influence abundance of bull trout Salvelinus confluentus. Connectivity among bull trout populations and trophic relationships among native and nonnative fishes in Glacier National Park (GNP), Montana, were examined. Competition between juvenile (or equal to 80 mm) bull trout and lake trout S. namaycush for cover habitat was examined in a laboratory environment. Connectivity among bull trout populations was inferred from genetic data. Barriers (i.e., waterfalls or equal to 1.8 m) reduced genetic diversity and increased genetic differentiation among populations. Genetic differentiation was positively related to the length of tributary stream sections between populations and populations within the same drainage were more similar than populations in different drainages. Competition between bull trout and nonnative lake trout for prey is a potential mechanism for declines in bull trout abundance. Stable isotopes analyses were used to examine trophic relationships among fishes in GNP lakes. Bull trout and lake trout were top-level predators among lakes (Delta15N analysis), lake trout occupied a higher trophic position than bull trout (Delta15N analysis), and bull trout and lake trout likely used different foraging habitats (Delta13C analysis). These data do not support the prediction that these species are complete competitors for prey resources in GNP. Cover habitat protects fish from predators and is competed for if limiting. Habitat use by juvenile bull trout and lake trout was experimentally evaluated. Bull trout and lake trout differed in habitat use. Lake trout avoided bottom habitat, bull trout avoided water column habitat when lake trout were present, and neither species selected cover habitat. The hypothesis that bull trout and lake trout compete for cover habitat was not supported. The landscape in GNP allows connectivity among bull trout populations that are not isolated by barriers and one-way dispersal past waterfalls is likely. This connectivity allows dispersal and colonization by nonnative fishes into GNP lakes. Bull trout and nonnative lake trout are not complete competitors for prey resources in GNP or cover habitat; however, future studies should examine trophic shifts by these species associated with prey limitation and diel variability in habitat use by these species.
