Today Te Kinga went for a walk down to the lake to learn what Mike (Solomon's dad) did for his job. Mike once a month goes to Lake Brunner and does some tests to see if the water isn't contaminated and is safe for the environment. Some of the tests are testing the temperature and also doing a Black disc visibility check, which is seeing how far he can see under the water. There is another test to see how much dissolved oxygen is in the water. The reason Mike sees how much dissolved oxygen is in the water is to see if the fish can breathe under water or not.
Here is a picture of today:
