Table 3. General limnological information for Kitlope Lake. The 1978–1980 data are means from weekly sampling through the growing season taken from Stockner et al. (1993); our 2005 data are means from four sampling events (7/05, 8/02, 8/23, 9/26) for nitrogen (N) and phosphorus (P) and two additional sampling events (5/30, 6/18) for all other variables. Originally published in Hill et al. 2009 by NRC Research Press.
