• <br />A-Pit at the southeast corner of the property has been filled as a lake <br />covering about 50 acres, as allowed by a County Special Use Permit and <br />a CMLRB permit. Both were approved in the 1980's.. The surrounding <br />shore areas will be graded and planted over the next 18 months. <br />B-Pit (at the southwest comer near Hygiene Road) has been a Cement <br />Kiln Dust (CKD} disposal pit for the last 10 years. It will be closed and <br />reclaimed within the next 18 - 24 months. <br />C-Pit at the center of the old quarry will remain as an active mine pit and <br />will be used for CKD disposal over the next 25 years. <br />E Pit, south of Hygiene Road, has been completely backfilled with <br />overburden and topsoiled. It will be seeded with winter wheat and dryland <br />pasture grasses this fall. This pit is the last location south of Hygiene <br />Road to be mined and reclaimed by Southdown. This property will be <br />sold to Mr. James Guercio this fall and will become part of his Caribou <br />Ranch. <br />MANAGEMENT AND MONITORING PLANS <br />The completed Dowe Flats Project Management and Monitoring Plans <br />were submitted to Boulder County on September 12, 1994. The following <br />discussion reviews each of the domains from this document and <br />incorporates other relevant events and information related to the <br />environmental studies for this project that have taken place since the year <br />one review. <br />Wi lif <br />An interim report, summarizing field work completed during the fourth year <br />of the five year winter raptor study, has been submitted to Boulder <br />County. Highlights of the report include: <br />Field work conducted this past winter sampled transitional activities in <br />both study areas. At the existing Lyons quarries, mining was being <br />completed and large scale reclamation activities were underway. In <br />Dowe Flats, quarry, conveyor and crusher construction was taking <br />place during the entire study period. <br />• The prairie dog and lagomorph (cottontails and jack rabbits) population <br />and distribution continues to gradually increase following the plague <br />epizootic of 1994. <br />Large raptor use in both study areas continues to track the prairie dog <br />prey base. <br />
