Abstract Stratification refers to the change in temperature with depth. In the lakes, this phenomenon will form due to the change in water's density with temperature. Three different layers will form due to stratification, epilimnion, metalimnion, and hypolimnion. The solar radiation will heat the upper layer, making it less dense than the lower layer, called the epilimnion. High-density water will be at the lower layer because the solar radiation won't penetrate the lower body of the water. This layer is called hypolimnion, and the middle layer is called metalimnion or thermocline.Lake Lagunita is a seasonal lake which depth varies through different seasons, perhaps (6-8) ft water depth since receiving inflow water from a stream and shallow water depth several inches or more minor due to evaporation during the warm season. (OS 200), it is a small instrument used to acquire data in oceanic and freshwater environments. The (OS 200) device was used to discover whether lake Lagunita experienced stratification. From the previous observation that the seasonal stratification does not occur in the lake, the wind and waves cause the warming water in the epilimnion to mix deeper and deeper, slowly incorporating hypolimnetic water through the metalimnion. The experiment shows the permanent stratification does not occur, but the stratified layer could appear in the lake lag during the day. The (OS 200) device was used to measure (conductivity, temperature, and depth) at nine different locations in the lake during different times. The measurement were taken at (6:45-7:20 AM), (10:00-11:00 AM), (1:30-2:10 PM), and (5:30-6:10 PM). The benefits of stratification are preventing the vertical mixing of toxic waste entering the lake; also, the dissolved oxygen level will affect as well, which directly impacts the aquatic life.
