Notes:

1. Lake height is based on a zero discharge elevation of 70.8 meters above sea level.

2. Lakelse is a high flushing lake with a turn-over of about 6 times per year.  This occurs roughly twice in the spring and fall and once in summer and winter.

3. High lake levels occur each spring usually peaking in May due to snow melt. Lake heights of 250 cm are not unusual.

4. Extreme levels can occur in the fall usually from rain on snow events: Nov. 2/1978 Lake level 4.20 m = 340 cm. They can also occur from unusual rain events alone: Sept. 29/1992 Lake level of 74.10 m = 330 cm.

5. See also the Lakelse Lake Management Plan Addendum (MoE March 2004) for a graph of seasonal
level behavior.

6. The 1/200 year flood height is 74.48 m Above Sea Level.

7. Lake Temperatures are measured at the deepest part of the lake which is in mid lake between BC Parks Campground and BC Parks Picnic site and is approximately 30 meters (100 feet) deep.
