A system of outdoor experimental ponds for the study of aquatic life under the effect of various controlled water temperatures has been designed. The ponds were to be located near power plants in Minnesota. The purpose of the study is to determine the feasiblity of maintaining certain specified temperature regimes in the proposed ponds. This was done by considering the available heating and cooling capacity and the environmental conditions prevailing at the selected site and making design calculations for the major elements of the system. Firstly, the limits of feasible temperature control were determined. Secondly, heating and cooling systems were devised and thirdly, a method of control was developed. For cooling, use of the well water is proposed, and, for heating, the water released from the thermal power station is going to be used. External and internal heat exchange systems were examined and both were found to be feasible and adequate. The study has the character of a feasibility study. (WRSIC abstract)
