IV_ <br />EXHIBIT G-Water Information <br />Existing Environment <br />The project is located 1,056 feet (.2 miles) north of the Crystal River. The Crystal River is a tributary to <br />the Roaring Fork River, and is part of the greater Roaring Fork watershed. There are no drainages, <br />streams, or other water features within the proposed rock harvesting area. The Crystal River water <br />influence zone (WIZ) is the riparian buffer that includes its floodplain, riparian vegetation, inner gorge, <br />unstable areas or highly erodible soils. The minimum width of the buffer on each side of a stream is the <br />greatest of 100 feet, or the mean height of mature dominant late-several vegetation (FSH 2509.25, zero <br />code). The project area is approximately 160 feet above the WIZ of floodplain of the Crystal River and <br />contains no riparian vegetation or wetlands. <br />Water Quality <br />There are no known water quality issues in the project area. The State-designated beneficial use of the <br />Crystal River below the project area is for "Aquatic Life Cold 1, Recreation la, Water Supply and <br />Agriculture" ) CDHPE 2008). The Crystal River is not on the State of Colorado 303 (d) list, meaning <br />that it has never been identified as having any water quality problems and that it meets is beneficial use <br />classification above. The closest water quality monitoring station with a long term data set is near <br />Redstone (HUC 14010004), although a U.S. Geological Survey (USGS) station is located near Marble as <br />well (USGS 1988 and 2008) <br />From EA htt ://www fs fed us/r2/whiteriver/urojects/conger-rock-harvesting- <br />area/Conger%20EA FINAL%20022509.pdf
