Here are some additional data from the CDR Shoreland Management Policy (1998):
|Lake Evaluation Summary|
||borderline mesotrophic to slightly eutrophic (chlorophyll α = 7.1 mg/m³)|
||62.2 years (low additional nutrient assimilation rating)|
||17.0 m (high additional nutrient assimilation rating)|
|Volume:||595 million m³|
|Water Quality Indicators:
||well mixed at spring overturn|
winter profile - anoxic in some areas.
|Nitrogen (total)||0.543 mg/L (eutrophic)|
|Phosphorus (total)||0.031 mg/L|
|Nitrogen:Phosphorus||17.5:1 (phosphorus limiting)|
|Water Clarity||Secchi depth = 7.17 m|
||Watershed Area = 15,900 ha
Low lying, poorly drained forests of interior douglas-fir have been subject to logging and clearing. South and west shores contain most of the housing development. New development occurring along south shore. Agricultural activity on north and west shores.
||Borderline mesotrophic to slightly eutrophic state, but water clarity relatively high. Has relatively long flushing period, but mean depth is quite high allowing for moderate assimilation of additional nutrients. High sensitivity, particularly in localized areas along the shoreline, such as in isolated bays.
