Eagle Park Reservoir <br /> Final Analytical Summary <br /> October 29, 1997 <br /> Water Quality Topics <br /> Topic 6 of the meeting notes for a Division inspection conducted on May 7, 1997 requested <br /> clarification on two topics related to water quality. The first requested that the parameters <br /> removed in the initial 1996 screening samples be reanalyzed to confirm their absence from the <br /> water body. Sample events 3-6 included the full suite of parameters resulting in the same <br /> conclusions drawn by the Titan Environmental Corp. in their September 9, 1996 letter report (see <br /> preliminary analytical summary for Eagle Park Reservoir dated April 15, 1996) <br /> The second clarification concerned aluminum as a parameter that needed to be sampled. While <br /> there is no standard for this parameter on Segment 3 of the Eagle River, several analyses <br /> showed that aluminum concentrations are at very low levels. Aluminum in Eagle Park Reservoir <br /> does not appear to be a concern with respect to water quality. <br /> Topic 7 of the above referenced meeting notes stated that hardness values for standards <br /> calculations should be determined in accordance with Water Quality Control Commission <br /> Criteria. CIVIC has included hardness data in this presentation and has evaluated-the water <br /> quality with respect to hardness dependent metal standards. Please refer to the rationale <br /> discussed in the attached September 3,1997 letter from Titan Environmental Corp. Water quality <br /> in the reservoir does not pose a threat to the standards that exist in the East Fork of the Eagle <br /> River. Dissolved forms of the contaminant were used in this evaluation (Topic 8). <br /> In response to Topic 10, CIVIC will be presenting results of the SAP to the Water Quality Control <br /> Division. The establishment of water quality criteria for the reservoir is not necessary given that <br /> • the water quality currently meets all standards for Segment 3 of the East Fork of the Eagle River. <br /> Storage and delivery of water to the Eagle River will occur as an exercise of water rights. CIVIC <br /> intends to maintain a monitoring program in the East Fork of the Eagle River. <br /> The water quality summary included with this package contains mean values of surface water <br /> samples taken at the north, south, and east shores of the reservoir between March 28 and August <br /> 22, 1997. A thirteenth sampling event occurred on September 11 in the middle of the reservoir. <br /> Samples for the final sample event were taken at the surface of the pond and at a depth of 15 <br /> feet. No significant differences exist between the two samples. Sample event 13 has not been <br /> included in the graphical comparisons provided because the samples were obtained from a <br /> separate sampling point. Sample 13 is considered representative of the water quality that <br /> currently exists in the reservoir. <br /> In August, CIVIC recognized that the reservoir water was of such quality it was capable of <br /> supporting a biotic community. CIVIC planted 55,000 fathead minnows, 1,650 cutbow trout, and <br /> 450 rainbow trout (certified whirling disease free) into the reservoir. Hay bales placed+in nearby <br /> lakes for 2 months were transported to the lake to inoculate the water with local aquatic flora and <br /> fauna. As of the date of this submittal, an aquatic community appears to have been successfully <br /> initiated in the reservoir. The presence of fish in Eagle Park Reservoir further verifies the return <br /> of this previously impacted facility to beneficial post-mining land use. <br />
