The Limnology of Two Dissimilar Subarctic Streams and Implications of Resource DevelopmentBecause of the relatively undeveloped condition of arctic and subarctic Alaska, an opportunity is presented to draw up water quality management plans before extensive perturbation. These plans cannot, unfortunately , be based upon those drawn up for more temperate regions where much is known about natural stream conditions, for in these Alaskan areas, little is known about the natural physical, chemical, and biological cycles of streams or about their ability to handle the stresses that will be exerted on them should development take place. The Chena River, in subarctic, interior Alaska, near the city of Fairbanks, has been studied to evaluate the impact of pending construction and operation of flood control structures (Frey, Mueller and Berry, 1970). This river however has already been developed, especially along its lower reaches where the city of Fairbanks is situated. The watersheds of the two streams chosen for this study roughly parallel each other, although the Chatanika River watershed is about twice as long as that of Goldstream Creek. In addition to the dissimilarity in size, these two streams also differ in regard to terrain, at least along the respective stretches that were studied. The Goldstream Creek study area runs through a bog and extensive muskeg. The Chatanika River, however, was for the most part sampled in the area of mountainous terrain. The intent of this study was to obtain comprehensive physical and chemical data, to survey the resident invertebrates, and to evaluate the assimilative capabilities of both streams.
