Marley Cooling Technologies • • 22 July 2002 <br /> San Joaquin County <br /> Inspection Report <br /> Receiving Water <br /> The Upper Morman Slough drainage course originates from the Calveras River near Bellota. The Upper <br /> Morman Slough drainage course then flows west-southwest from Bellota, south of the Calaveras River. The <br /> Stockton Diverting Canal, which receives the discharge from Outfall 001, is an engineered drainage which re- <br /> connects Upper Mormon Slough to the Calaveras River on the east side of Stockton. From 1 October to 1 <br /> April each year, the East Stockton Water District dams the Calaveras River at its fork with Upper Mormon <br /> Slough, diverting flows through Upper Mormon Slough and the Stockton Diverting Canal. <br /> From 1 April to 1 October each year, flows are split between the Calaveras River and Upper Mormon Slough. <br /> A series of check dams are installed along the Calaveras River, Upper Mormon Slough, and the Stockton <br /> Diverting Canal to provide irrigation water for adjacent farmers. During this time, there are periods of limited <br /> or no flow in the Stockton Diverting Canal. <br /> At the time of this inspection, the discharge from the Marley facility outfall to the Stockton Diverting Canal <br /> appeared clear, with no foaming, scum, or floating materials. The Canal contained pockets of water several <br /> feet deep,with no noticeable current or flow. <br /> Yy fi�"^'y} m t .✓ pza3 Oyu '�� <br /> 4 <br /> Stockton Diverting Canal and Fremont Street Bridge Outfall 001 Discharge to the Stockton Diverting Canal <br /> Downstream of Discharge View North <br /> SUMMARY: <br /> No violations of Order No. 93-221 were identified during this inspection.
