2.1.2 Water Quality Data <br />2.1.2.1 Water Quality Analysis <br />There is no water quality data for Savage Lake. Additionally, there is no information on fishery, <br />macroinvertebrates, phytoplankton, or zooplankton. <br />2.1.2.2 P8 Modeling Results <br />The P8 Model of the Savage Lake watershed was run for wet, dry, and average climatic conditions. <br />Water and total phosphorus loads to Savage Lake were determined for each climatic period. The <br />results of this modeling are summarized in Table 2 -1. <br />Table 2-1 P8 Estimated Watershed Runoff and TP Loads to Savage (East and West) Lake under Wet, <br />Dry, and Average Climatic Conditions <br />Climatic Condition <br />(Water Year) <br />Parameter <br />Load <br />Wet (10/1/01 - 9/30/02) <br />Flow <br />ac -ft <br />217.45 <br />TP <br />Ibs <br />154.12 <br />Average (10/1/00- 9/30/01) <br />Flow <br />ac -ft <br />252.98 <br />TP <br />Ibs <br />144.58 <br />Dry (10/1/88- 9/30/89) <br />Flow <br />ac -ft <br />161.22 <br />TP <br />Ibs <br />109.08 <br />It is important to note that climatic condition periods were selected based on depths of precipitation <br />over a 17 -month period that included the summer before the water year of interest because it is <br />assumed that the water and TP load to the lake during this period affects the following year's spring <br />TP concentration. During the 12 -month period from October through September (the water year), <br />however, the water load to the lake was slightly higher during the average year than the wet year. <br />Conversely, the TP load was higher in the wet year than in the average year over this 12 -month <br />period due to the fact that higher TP loading is often associated with the smaller, more frequent storm <br />events like the ones that occurred between October 2001 and September 2002. <br />2A.3 Recommendations <br />2.1.3.1 Water Quality Goals <br />As previously mentioned, Savage Lake is actually not a district- managed lake but rather a wetland. <br />Therefore, no preliminary District water quality goals have been established for Savage Lake.
