All <br />appropriate maps are enclosed. <br />Section 2.0 is the Annual Hydrology Report and is composed of ten subsections. <br />Subsections 2.8 and 2.9 are proposed reductions in monitoring programs. <br />2.1 Climatological Data <br />2.2 Pit Dewatering <br />2.3 Mining Advancement and Ash Disposal <br />2.4 Monitoring Points <br />2.5 Hydrological Data <br />2.6 Hydrological Trends <br />2.7 Spoil Spring Sampling <br />2.8 Monitoring Well Abandonment <br />2.9 Hydrological Monitoring and Analysis Reductions <br />2.10 Lux Application for Water Rights <br />Section 3.0 is a report on Trapper's Drainageway Reconstruction efforts 1967- <br />89. It consists of a narrative segment describing our reconstruction methods <br />and results as well as a map showing the locations of our drainageway recon- <br />struction efforts minewide. In 1989, approximately 7,600 ft of drainage <br />reconstruction was performed. The map also shows diversion ditches to be left <br />as part of the reclaimed land surface. Peak flow data from the 10-year, 24- <br />hour parshall flume located in Coyote drainage are included. Normally, as- <br />built profiles for newly reconstructed drainage segments are provided to the <br />Division, however, due to adverse weather conditions following completion, <br />this was not completed during 1989. Drainage profiles will be completed as <br />weather permits and should be_submitted to the Division by late spring 1990. <br />/ Based on t~ success of our drainage reconstruction prdgram, Trapper proposed <br />to no longer provide the Division with as-built drainage profiles in future <br />Annual Reports. <br />~ -- -- - -~~'r -' <br />.~.J. rnp~~ u>.t.~ ~i.>r' <br />~ItlW-(WI/"_,_I0.L-SO (~,J SIP/!~ W-Q <br />P.O.
