r <br />• Under the benchmark loading conditions, the Stubbs Bay outflow load to <br />Maxwell Bay is 60 kg. Therefore improvements to Stubbs Bay will result in <br />relatively small reductions to the Maxwell Bay load. <br />1.4 Recommendations for Feasibility Study <br />Should the MCWD Managers order a feasibility study, it should consider the following: <br />• Improvements can be made to the water quality in Stubbs Bay. Reductions to the <br />internal load are the most promising to improve the trophic state of the bay. <br />• The study should investigate various internal load controls such as alum treatment <br />or injection, hypolimnetic aeration with chemical addition, and artificial <br />circulation. Phased or gradual treatment may be preferred to a large, one-time <br />treatment which may alter the balance between algae and macrophytes towards <br />macrophyte dominance. <br />• There is some potential for external load controls to have a measurable effect in <br />conjunction with internal load controls. The existing average inflow <br />concentration of approximately 2S0 ugl. is high enough that some reduction <br />strategies may be effective. Inflow volumes and concentrations may be expected <br />to increase with future development. <br />• The feasibility study should consider projected changes in land use and their <br />effects on external phosphorus loads. <br />• The goal-setting process with stakeholder input should be followed. <br />T bU504»S^»a lUpBWSiMbtw Bay IUpatt4»B Stubbs Bay Diagnostic Report <br />—------ <br />I? <br />I <br />a tin A I’oraoin
