The invention provides a channel water depth and near-surface flow velocity measuring device. The channel water depth and near-surface flow velocity measuring device comprises a water depth photoelectric positioning part, a shading sleeve vertical position regulating and controlling part and a surface flow velocity measuring part. The laser lamp emits light to enable the photoelectric plates to generate current so as to enable the indicator lamps to emit light, and the distance between each photoelectric plate and the bottom end of the photoelectric plate placing barrel is certain, so that the maximum value and the minimum value of the distance between the light-emitting indicator lamps and the bottom end of the photoelectric plate placing barrel are found out, and the difference value is approximately equal to the water depth; the shading sleeve vertical position adjusting part can ensure that the bottom of the shading sleeve is always flush with the water surface, and can always shield light above the water
