In this quarter, no discharges were observed at <br />Points 005, 009, 011 and 014. Intermittent flows were observed at Point <br />013. Construction of Pond 014 was completed in September 2001, no <br />discharge has occurred as of the end of this quarter. <br />Vehicle access to Points 004, 005, 008, 009, 010, 015, 016 and 017 was <br />closed starting in November due to snow. Monthly visits (at all sites <br />except 015) were performed by snowmobile or snowshoe. Exceptionally <br />deep and light snow prevented safe access, even with a snowmobile, to <br />Point 015 in January and February. The snow had set up enough in March <br />for snowmobile access to Point 015. <br />No excursions of effluent limits occurred this quarter. Please contact <br />me at 970-276-5209 if you have any questions. <br />Sincerely, <br />~~~~ <br />Dennis Jones <br />Hydrologist I <br />cc: Division of Minerals and Geology <br />Attn.
