Fig. 11. Sampling stations for long-term bass lake monitoring.
The Bioaccummulation Oversight Group (BOG) Bioaccumulation Monitoring Program is implementing a long-term plan to track the status and trends of bioaccumulation in 190 bass lakes throughout California. The 190 lakes have been divided into five subsets (or “panels”), and one panel is sampled every other year. After 10 years all of the panels will have been sampled, and the cycle will begin again so that timely information for each lake is generated once every 10 years. This is a shapefile of all 190 sampling stations as classified by panel group.
