Transect - relates to the transect number on the map 
Distance from Shore - distance from the shoreline to the sampling location in metres 
Depth - surface samples taken approximately 50cm below the water surface 
Sample Type - samples taken within the lake 
EC - Escherichia coli (counts/100 mL) 
EC_RL - Escherichia coli lab reporting limit 
P - Total phosphorus (mg/L) 
P_RL - Total phosphorus lab reporting limit
