The Upper Etowah River watershed is in northern Georgia, bounded on its downstream end by the Lake Allatoona Dam and covers approximately 1,120 square miles. Although the dam is only 35 miles from downtown Atlanta, forested land cover and a small percentage of scattered pasture, residential, and commercial/ industrial land uses dominate the watershed. The monitoring plan is intended to i) be comprehensive, ii) help address multi-jurisdictional watershed management objectives, iii) focus on ecological condition at multiple spatial scales, in response to the 1972 Clean Water Act emphasis on biological integrity, and iv) to help meet the State of Georgias requirements for watershed management plans. The purpose of this project, thus, is the development of a valid and technically defensible, long-term monitoring design for the Upper Etowah River watershed. The set of objectives developed by the Lake Allatoona/Upper Etowah River Watershed Partnership required an approach that incorporates sites selected based on expected problems or issues (targeted), as well as sites from which data could be aggregated for assessments at broader spatial scales (probability-based). In addition, the site selection and data collection efforts have three broad components: water quantity, water quality, and water resource quality. The resulting network design is a set of sites that will, in part, be sampled annually; intermittently; and as part of a regular, rotating-basin schedule. Constituents to be sampled include selected laboratory and field chemistry, various aspects of flow and physical habitat quality, benthic macroinvertebrates, and fish. Over a 6-year period, these data will be gathered from approximately 400 locations throughout the upper basin. Implementation of the program will require training, tracking of data quality characteristics, and performing analyses focused on answering, with known confidence, the stated objectives of the program.
