Summary This paper describes the design, construction and use of a portable battery‐powered, submersible spectroradiometer. The distribution of energy underwater is determined by measuring successively through six sensors fitted with interference filters which partition the underwater spectrum. This system also contains a quantum sensor which detects the photosynthetically active radiation under water. The instruments’ small size and battery operation make it especially useful for studying small lakes or reservoirs from small boats. Measurements taken from Pawnee and Wagontrain, two of the Salt Valley Reservoirs in eastern Nebraska, are given as examples of the use of the instrument.
