Alaska Monitoring and Assessment Program 2006 Tanana River
In 2004, a cooperative project between DEC and United States Geological Survey began a pilot AKMAP project to evaluate the USEPA Environmental Monitoring and Assessment Program protocols on the Tanana River Basin. This survey combined results from the 2004 Tanana River Wadeable Streams survey with results from this survey, a focus on the Tanana River mainstem. Water-quality data was collected from 84 sites in Tanana River basin during water years 2004 through 2006 (October 2003 through September 2006). A broad range of chemical analyses are presented for 93 sets of samples collected at 59 tributaries to the Tanana River and at 25 locations along the mainstem.
DEC, USGS, and UAA Environment and Natural Resource Institute collected and processed water quality, sediment, biological, and habitat measurements. Parameters included pH, dissolved oxygen, conductivity, flow, DOC, and trace elements) stream macroinvertebrates, periphyton, and physical habitat. These data are to provide a means to assess baseline characteristics and establish indicators that are ecologically important, affordable, and relevant to society.
The study area was selected because a wide variety of land uses occur within the unit. These activities include forestry, agriculture, mining, recreation, subsistence, national defense, supporting urban, suburban, and village communities. Federal and State conservation units such as national parks and wildlife refuges also are located in the Tanana River basin.
