Bar graphs depicting spring flows from 1979 to present have been included for the 1986 Annual Hydrology Report and are contained in Appendix D. Springs were monitored when accessible and the records for the most part are good. In early spring G-25, G-28a, and G-31 were made inaccessible by landslides in Lone Pine Gulch and on the road to the springs. 1.3 Ground Water Monitorin4 ' During Water Year 1986 water levels were monitored monthly at 30 wells when weather permitted. The location of these wells are shown on F~chibit I. Wells included in the hydrology monitoring program for water year 1986 are shown ' in Table 1.2-2 along with monitoring frequency, type, and sampling. Groundwater well tronitoring data such as water level (if present), quality, ' dates, and other pertinent information is contained in the Quarterly Hydrology Monitoring Reports. Well hydrographs for the 1986 water monitoring quarters are also contained in the reports. These hydrographs are cumulative for the year. ' Monthly water level records were near complete at all locations. There has been a constant problem over the last 2 years with an obstruction in well 38-H-2 which has caused sane lost data as the electric level probe will not always go ' past the obstruction and gets hung up on the way out. Wells 38-H-1 and 38-H-3 also are problematic in than crorulensation of moisture inside the casing acts as a water level and causes the electric probe to malfunction before it reaches the ' water. This has caused considerable lost data in well 38-H-3 and to a much lesser extent in 38-H-1 Nbnitoring of wells WR-2 and WR-3 was discontinued upon approval from the ' Division in the 3rd quarter of 1985. Water cascading down the casing in well SCM-13 caused a "no-reading" in April. ' This has happened several times during spring runoff in previous years. Well GP-2 at the lower refuse pile area was inadvertently destroyed by construction in late December or Farly January as it was covered with snow. There are no ' plans to replace this well as it is located in the interior area of the refuse pile and was drilled as a test hole. 1.4 Mine Water Monitoring I As in 1965 a mine inflow survey was conducted during water year 1986. An underground mine map with inflow areas and sample locations delineated is I included as FSChibit III. The mine inflow survey was conducted June, 1986 to more closely assess peak inflows from spring runoff. The mine inflow survey looked at all previous inflow areas as well as all area mined since the last survey in December of 1985. The three main areas from the previous survey which 1 had produced sustained inflows in excess of 3 gpm remained active in 1986 but at (4)
