Alaska Monitoring and Assessment Program 2004-2005 Tanana Watershed Wadeable Streams
The Tanana River watershed, located in interior Alaska, was selected for the location of the EMAP wadeable streams demonstration project. This region was chosen because of the wide variety of land uses occurring within the watershed, including forestry, agriculture, mining, recreation, subsistence, national defense and communities with suburban, urban and village characteristics. The first sampling phase took place in the summer of 2004. The second and final sampling phase occurred in the summer of 2005.
Field sampling and logistical support was done through partnerships with Environmental Natural Resources Institute (ENRI) at the University of Alaska Anchorage (UAA) and University of Alaska Fairbanks School of Fisheries and Ocean Science (UAF SFOS). US Environmental Protection Agency (USEPA) and US Geological Survey are analyzing the water samples for various chemical parameters. Data reduction and statistical analysis support is being provided by the US EPA. Stream invertebrate identification is being conducted by UAA ENRI.
EPA coastal and wadeable stream assessments focus on indicators that are ecologically appropriate, economically reasonable and relevant to society. Due to reduced scale and ease of measuring connections with the terrestrial habitat the wadeable stream protocol conducts a more extensive physical habitat assessment than that of coastal surveys. The goal of both types of surveys remain the same, to provide aggregated assessments of water quality, typical as percent of area for coastal or stream length for wadeable streams, with a known reliability.
