Montana's Clark Fork River Basin Task Force: a vehicle for integrated water resources management?

This article examines what is generally considered to be an unattainable goal in the western United States: integrated water resources management (IWRM). Specifically, we examine an organization that is quite unique in the West, Montana's Clark Fork River Basin Task Force (Task Force), and we analyze its activities since its formation in 2001 to answer the question: are the activities and contributions of the Task Force working to promote a more strongly integrated approach to water resources management in Montana? After reviewing the concepts underlying IWRM, some of the issues that have been identified for achieving IWRM in the West, and the Montana system of water right allocation and issues it faces, we adapt Mitchell's IWRM framework and apply it to the analysis of the Task Force's activities in the context of IWRM. In evaluating the physical, interaction, and protocol/planning/policy components of IWRM, we find that the Task Force has been contributing to the evolution of Montana's water resources management towards this framework, though several factors will likely continue to prevent its complete realization.

Air toxic emissions from snowmobiles in Yellowstone National Park.

A study on emissions associated with oversnow travel in Yellowstone National Park (YNP) was conducted for the time period of February 13-16, 2002 and February 12-16, 2003. Whole air and exhaust samples were characterized for 85 volatile organic compounds using gas chromatography. The toxics including benzene, toluene, ethylbenzene, xylenes (p-, m-, and o-xylene), and n-hexane, which are major components of two-stroke engine exhaust, show large enhancements during sampling periods resulting from increased snowmobile traffic.

Blowing smoke in Yellowstone: air quality impacts of oversnow motorized recreation in the park.

Snowmobile use in Yellowstone National Park has been shown to impact air quality, with implications for the safety and welfare of Park staff and other Park resource values. Localized impacts have been documented at several high-use sites in the Park, but the broader spatial variability of snowmobile emissions and air quality was not understood. Measurements of 87 volatile organic compounds (VOCs) were made for ambient air sampled across the Park and West Yellowstone, Montana, during 2 days of the 2002-2003 winter use season, 1 year before the implementation of a new snowmobile policy.
