Abiotic factors include: Sunlight, Rainfall, Sedimentation, Weather, Minerals, Temperature.

Changes that would impact the biotic factors include:

Pollution: pollution such as water pollution and air pollution will adversely impact the biotic factors.

Human activities: such as overfishing, rechanneling of the water for purposes such as irrigation, domestic or industrial use, or dredging of the bottom of the lake.
