The dry conditions, summer drought, also reduced the number of active discharge sites after the spring <br />runoff season. All surface water flows were diminished. There were no storm events approaching the <br />intens'tty of a 10-year, 24-hour event. <br />Drainageway reconstruction and stabilization, plus other water channelization and velocity decreasing <br />practices have reduced the sediment loading and erosive potentials across the mined areas at Trapper. <br />2.7 Sooil Sorina Samolin <br />During 1988 we conducted the inftial spoil spring inventory across our mined land boundaries. This survey <br />is required by Section 4.8.5.2a of the permit. The survey was made April 20th through May 4th. <br />We located only one spring meeting the 5 gallon per minute reporting and monitoring criteria. That seep, <br />Cottonwood spring, is located in the Coyote Gulch drainage system below the northern limits of Derringer <br />pit. See Map M-52 and the 1988 AHR map. <br />This survey was checked wRh an on-site visd May 12, 1988. The CMLRD team visited Coriornvood Seep, <br />Colt Seep and No-Name Seep. Water quality samples and flow measurements were taken. They also <br />sampled No-name seep for baseline information even though the flow was less than the criteria. <br />WSH/jsb [CMLRD\88REPT] <br /> <br />C~ <br />
