A third consideration <br />is the quality of the discharge from point sources and its compliance with <br />the applicable regulations. The NPDES permit sampling requirements address <br />this issue so it is possible to provide detailed information on this <br />subject. This report will describe the results of the monitoring done <br />during 1984 with special emphasis on the constituents of most interest. <br />The report is organized in five sections: A discussion of the <br />hydrology monitoring program; a discussion of the hydrology monitoring <br />results; the crop productivity monitoring results; wildlife monitoring <br />results; and appendicies containing the hydrology data and figures. <br />I1. HYDR~LnGY MnNITnRr~iG ~Rnl:RAt4 <br />Samvling Locations <br />The present monitoring network is a modification of the network used <br />during baseline monitoring for the initial SMCRA permit application. The <br />modifications are mostly simplifications justified by the monitoring <br />records from 1978 to 1983• Continuous streamflow records are made for <br />Trout Creek above the mine (TR-a), and for the Koll Ditch and Homestead <br />Ditch during ice free periods (usually t4ay through Tlovember). Instant- <br />aneous streamflow is recorded on Trout Creek below the mine (TR-b). <br />Instantaneous streamflow is recorded on yak Creek near the Edna Mine tipple <br />(OK-a). Surface water samples are collected above and below the mine on <br />Trout Creek (TR-A, TR-B, and TR-D), above and below the tipple on yak Creek <br />(nK-A, and nK-B), and at the NPDES discharge points near the tipple and at <br />the ponds below Center Ridge and West Ridge. Groundwater samples are <br />
