The invention relates to the field of water level monitoring devices, in particular to a reservoir water level monitoring device which comprises a tunneling structure, a sampling structure, a measuring structure, a supporting structure, a driving handle and a driving structure. The tunneling structure is arranged at the end portion of a measuring structure deviating from the most end portion of the supporting structure; and thus the measuring structure rotated helically conveniently to drive the tunneling structure to be inserted into reservoir sludge. A distance between the position, bonded to the tunneling structure, of the sludge and the position, making contact with the liquid level, of the measuring structure is equal to the water level depth of the reservoir; and the length of the position of the sludge bonded to the tunneling structure is equal to the depth of the sludge. The sampling structure is arranged in the tunneling structure and is connected to the driving structure andthus the driving structure is conveniently driven by the measuring structure to drive the sampling structure to sample the sludge in the reservoir, so that the sludge at different depths is conveniently collected. Whether heavy metal in the sludge in the reservoir exceeds the standard or not is conveniently observed, so that the reservoir is conveniently treated in time according to sludge detection data of the reservoir.
