| Abstract: | ABSTRACT: Samples were collected upstream and downstream of Schwatka Lake, Yukon Territory, to examine nutrient transport through a small northern impoundment. Annual loads were estimated for total phosphorus, nitrate plus nitrite, total dissolved nitrogen, silicate, total inorganic carbon, and total organic carbon. Transport of these materials out of the impoundment was greater than estimated for the upstream location. Results of a short term temporal study confirmed that the output exceeded the input to the lake. There are several processes which might be responsible for this occurrence, of these, ground water contributions appear to be the active process. |
