| Abstract: | 2015 marked the 14th year of milfoil control in Lake Colby using hand harvesting and limited benthic matting. Control was initially focused on limited areas of the lake, while untreated areas grew unabated. Thus a whole-lake control effort initiated in 2006 resulted in a large increase in milfoil removed compared to the first 4 years. Whole-lake control has been conducted annually since 2006 and the data suggests that this effort has produced a more or less stable milfoil population beginning in 2009. We believe this demonstrates that the control program has been successful in achieving maintenance control, however sustained control will require annual diver hand harvesting in perpetuity. Note: data are included in final report. |
