Runoff from the majority of the Lake Owasso watershed is routed through <br />stormwater ponds and /or natural wetlands prior to discharge into the Lake. <br />Therefore, the watershed runoff was identified being less important than other <br />sources of phosphorous to the Lake. <br />Lake water quality can benefit from watershed wide implementation of infiltration <br />BMPS. <br />Internal loading and the export of phosphorous occurs at the Central Park's east <br />and west wetland complexes (5 to 9% of the external phosphorous loading comes <br />from these two sites. Further study is needed to determine why and how to <br />address this issue. <br />Recommendations: <br />• Further study and monitoring the water quality of the Shallow areas of the Lake to <br />better understand the water quality and mixing dynamics as the result of wind and <br />motorboat activity, etc. <br />• Incorporate infiltration BMPS throughout the watershed. <br />• Manage Curlyleaf pondweed through herbicide application. <br />• Further study the Central Park west and east wetlands, including core samples, to <br />determine why the export phosphorous. <br />• Study Carp and their impact on the Lake's water quality. <br />• Implement "non - structural BMPS" throughout the watershed. <br />Fall street sweeping <br />Discourage waterfowl feeding <br />Encourage vegetated shoreline buffers and restoration <br />Continue to educate the public about yards and household BMPS <br />Evaluate Road salting practices <br />
