BULL SEEP -CAMAS WETLAND ~EATIDN REPORT Area 5 This site is located in a pasture east of McKay Road and south of 104`h Avenue. Active ground water seeps supply hydrology to these wetlands and are located along McKay Road. Several agricultural ditches drain this azea and are used to irrigate nearby pastures and cropland. The pastures in which the seeps are located are periodically flooded during the growing season with water from off site to irrigate upland areas. These factors have complicated the determination of the natural wetland boundaries in this azea. Boundaries were based on observations made during several field visits over afour-month period from January through April of 1999. Two major irrigation ditches; the Ford Seep Ditches, A and B, originate from [his area then proceed east across the property. The origins of these ditches are located at the north and south ends of the wetland azea. Both seeps are dominated by cattail with the presence of prairie cord grass. Three square and hydric grasses with the occasional cattail dominate portions of the pasture that were included in the delineation. Grass identification was complicated in this area by grazing activities. Soil in this azea is a layer of clay roughly 12-18 inches thick on top of sand and gravel, which is saturated. This layer of clay acts as a cap, which separates ground water from surface runoff. When this clay layer is breached water flows up from the sand and gravel layer and floods the surface. The seeps in this azea have natural origins bu[ are frequently enhanced and altered by agricultural practices. Trenches and the seep origins are periodically cleared of sediment and vegetation to ensure they continue to flow at moderate to high volume. No further seeps appeaz to originate north or south of this location along McKay Road.
