BULL SEEP -CAMAS WETLAND DELINEATION REPORT <br />Area 5 <br />' This site is located in a pasture east of McKay Road and south of 104' Avenue. Active ground <br />water seeps supply hydrology to these wetlands and aze located along McKay Road. Several <br />agricultural ditches drain this area and aze used to irrigate neazby pastures and cropland. The <br />pastures in which the seeps aze located aze periodically flooded during the growing season with <br />water from off site to irrigate upland areas. These factors have complicated the determination of <br />the natural wetland boundaries in this azea. Boundaries were based on observations made <br />during several field visits over afour-month period from January through April of 1999. <br />Two major irrigation ditches; the Ford Seep Ditches, A and B, originate from this azea then <br />proceed east across the property. The origins of these ditches aze located at the north and south <br />- ends of the wetland azea. Both seeps are dominated by cattail with the presence of prairie cord <br />grass. <br />Three square and hydric grasses with the occasional cattail dominate portions of the pasture that <br />were included in the delineation. Grass identification was complicated in this azea by grazing <br />activities. <br />' Soil in this area is a layer of clay roughly 12-18 inches thick on top of sand and gravel, which is <br />saturated. This layer of clay acts as a cap, which sepazates ground water from surface runoff. <br />- When this clay layer is breached water flows up from the sand and gravel layer and floods the <br />surface. The seeps in this azea have natural origins but aze frequently enhanced and altered by <br />agricultural practices. Trenches and the seep origins aze periodically cleazed of sediment and <br />- vegetation to ensure they continue to flow at moderate to high volume. <br />No fiuther seeps appeaz to originate north or south of this location along McKay Road. <br /> <br />Sections 16, I7, and 9 of Township 2 South, Range 67 Wes[. 3 <br />39° 53' 15" Latitude and 104° 53'50" Longirude, UTM ('0870'" E. 4014800o''N.). <br />15 <br />
