General factors for reservoirs like this
These are common influences for this type of lake. They do not identify the cause of a specific current change unless an operator update confirms it.
Rainfall & inflows
Rain and upstream river inflows can raise reservoir levels, especially after storms.
Downstream releases
When an operator releases water through a dam, reservoir storage can fall and downstream flows can rise.
Published reference elevation. Not necessarily a fixed year-round target for every project.
A winter / seasonal pool elevation is published, but Lake Insights does not have verified seasonal operating dates for this lake.
