WLPP Water Quality Monitoring Program
The WLPP, in cooperation with the Lake Partners Program of the Ministry of the Environment and Climate Change, will complete a significant
water sampling program in 2018. Water samples will be taken and physical measurements made at nine locations. Total phosphorous, calcium,
dissolved organic carbon, sulphate and chloride will be measured once a month and every month during the spring, summer and fall.
Secchi depth and temperature readings will also be taken. We will also be measuring specific conductivity in all parts of the lake
and feeder streams and also Lowney and Darling Round Lakes. This initiative will give us information on the hydraulics (water flows)
in White Lake and also help explain some of the trends observed and reported in our 2017 Water Quality Monitoring Program Report.
This year's work will build on the research done since 2014, and will continue to determine the year to year trends in phosphorous
concentrations throughout the lake. We will also gain important information on the relative sources of phosphorous including contributions
from sediments. Of particular interest is the monitoring of White Lake for changes in chemistry and water clarity resulting from the
presence of zebra mussels. The significant effects of zebra mussels were first noted in 2016 and it is expected that changes will
continue to occur for the next several years.
One new initiative which will be added to our program this year involves a collaboration
with Professor Vermaire from Carleton University. A graduate student under the direction of Professor Vermaire will complete a project
stuying the sediments of the lake. This student is in the process of completing a paleolimnological study of sediments taken from
the deepest point of the lake. This will provide us with a recent history of nutrient loading in White Lake. We will also continue
to monitor any changes in the amount (volume) of aquatic plants in the lake and to track changes which could be related to human activity,
climate change and the presence of zebra mussels.
Also, we will be taking accurate depth measurements to monitor lake levels
throughout the ice-free season. As part of our 'algae-watch' initiative, we will be looking for algal blooms and the presence of significant
blue-green algae populations in the lake which could result in high concentrations of toxins in lake water, which is an important
public health issue. We are also creating a photomicrographic catalog of algae found in White Lake (see new section on website).
