Hamilton Harbour water clarity response to nutrient abatement / S. Painter, L. Hampson and K. McCabe.: En13-5/90-14E-PDF
"Hamilton Harbour is one of 42 areas of Lakes concern in the Great Basin. The Provincial and Federal governments are committed to develop a Remedial Action Plan (RAP) to restore the beneficial uses of the Harbour. Swimming and fish habitat are two of the beneficial uses identified by the Hamilton Harbour Stakeholders. Both uses require improvements in the Harbour's water clarity. Beginning in 1988, the addition of a pickle liquor step at the Hamilton STP successfully reduced the phosphorus loading into the Harbour from all sources by 25%. A comparison of the 1987 and 1989 Harbour data showed that Secchi disc transparency increased between 40-50 cm, chlorophyll decreased 20 ug/L, and seston decreased 2.5 mg/L. The 1989 summer mean for Secchi disc transparency was 193 cm. The area of submerged vegetation could then increase 10 ha from its present 90 ha. The water clarity guideline for swimming is still violated in the western end of the Harbour. The data also suggest that Secchi disc transparencies in the 3 m range are attainable when chlorophyll concentrations are below 7 ug/L; With this increase in water clarity, aquatic plant distribution could then increase to 170 ha, nearly double the present distribution"--Abstract.
