RM-RP-325: Water chemistry of Rocky Mountain Front Range aquatic ecosystems

Musselman, Robert C.; Hudnell, Laura; Williams, Mark W.; Sommerfeld, Richard A. Water chemistry of Rocky Mountain Front Range aquatic ecosystems. Res. Pap. RM-RP-325. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Forest and Range Experiment Station. 13 p.

A study of the water chemistry of Colorado Rocky Mountain Front Range alpine/subalpine lakes and streams in wilderness ecosystems was conducted during the summer of 1995 by the USDA Forest Service Arapaho and Roosevelt National Forests and Rocky Mountain Forest and Range Experiment Station, and the University of Colorado Institute of Alpine and Arctic Research. Data were collected to examine the water chemistry of Front Range high-elevation lakes and their sensitivity to atmospheric deposition, particularly nitrogen saturation. Water chemistry data from synoptic surveys of high-elevation lakes in wilderness areas of other National Forests in Colorado are also included in this report. Because of the extent, uniqueness, and potential value of the data collected, the entire water chemistry data base including over 265 samples from more than 130 lakes and streams is presented. Preliminary data examination indicates that many lakes have detectible nitrate concentrations, nitrate concentrations are higher early in the season and decrease as the season progresses, and inlets often have higher nitrate concentrations than outlets. Detailed data analysis and interpretation, its relationship to landscape characteristics, and the implications for ecosystem response and management will be presented by the authors in subsequent manuscripts in preparation.
