The lake receives a high phosphorus loadingfrom the natural weathering of apatite. Before the lime treatment, less than half of the epilimnetic phosphorus precipitated with calcium carbonate. In 1983, the addition of 23 tonnes of Ca(OH)2 removed 80% of the chlorophyll a and 97% of the soluble reactive phosphorus (SRP) from the epilimnion. In 1984, the addition of 16 tonnes of lime removed more than 90% of the chlorophyll a and 60% of the SRP from the epilimnion. Most of the precipitated phosphorus dissolved in the hypolimnion. Several changes in lake chemistry indicated that lime treatment would produce more than a seasonal improvement in water quality"--Management perspective. |
