In this quarter, no discharges occurred at Points 005; 009 and 014. Intermittent flows were observed at Points 002,;010, 011, 012 and 015.. Point 013 has not been constructed yet. Construction of Pond 014 was completed in September 2001, no discharge has occurred yet. Construction of Pond 017 was completed in November 2002. Due to a lack of a safe access road and deep winter snow, this site was not visited this quarter. No mine related disturbance has occurred in the Pond 017 drainage basin yet. This site will be visited. in May, once the snow melts off. A better access road will be built to this pond this summer. Vehicle access to Points 004, 008, 009, O15 and 016 was closed in mid-November due to snow. Monthly visits were performed by snowmobile or snowshoe, except to Pond 015. Snow pack was not solid enough to run a snowmobile on this steep narrow road until March. Due to the low water level in this pond noted last quarter, no flow was likely in January or February. No excursions of effluent limits occurred this quarter. Please contact me at 970-276-5109 if you have any questions. $\ncerely, Dennis Jones Hydrologist I ~c: Division of Minerals and Geology Attn.
