Abstract
The Water Cherenkov Detector Array (WCDA) is one of the components of the Large High Altitude Air Shower Observatory (LHAASO). WCDA, divided into 3 separate arrays, will make survey observation on the gamma-ray sky of 100 GeV - 30TeV. The first array (150m × 150m), denoted as WCDA-1, has already be operated since April 2019 and one more array of the same size, referred to as WCDA-2, has also been in operation since November 2019. The third array, WCDA-3, with a size of 300m × 110m, has been tested at beginning of 2021 and the full array of WCDA is being in the testing since March 2021. This paper will describe the operation status of the LHAASO-WCDA since April 2019.
