AQUATIC RESOURCES A AND B (4.28 ACRES AND 2.20 ACRES) Aquatic Resources A and B are situated in the bottom of two manmade remnant reclaimed shallow aggregate pits. PEM wetland habitat has developed in the topographic lowest points within the two pits. Aquatic Resources A and B are manmade excavated wholly in uplands, recontoured, revegetated and routinely mowed. Two culverts appear to direct irrigation water into the pits (one culvert from the south in Aquatic Resource D) and one from an upland basin from the north. These culverts appear to direct seasonal irrigation water into the pits, however there is no outflow. Aquatic Resources A and B are surrounded entirely by uplands/uplands berms with no direct surface connection to other Waters of the US. Overall, the vegetation communities of Aquatic Resources A and B are dominated by species such as saltgrass (Distichlis spicata), narrowleaf cattails (Typha angustifolia), reed canarygrass (Phalaris arundinocea), common three-square (Schoenoplectus pungens), and narrowleaf dock (Rumex stenophyllus) areas contain a seasonal flooded water regime. The dominant species within the wetland areas consists of species designated as OBL-FACW. 6
