For locations of the wetlands, see Figures 1 (Miller and Walker Creek basins) and 2 (Des Moines Creek basin). MILLER CREEK BASIN A. Runway Safety Area/North Airfield Aquatic resources located in this area include: Wetlands 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, a portion of Wetland A1, FW5, FW6, a portion of Miller Creek Water Quality Functions Some of the wetlands in this area have limited opportunity to perform nutrient/sediment trapping, due to the limited input of surface water or sediments to the wetlands (Wetlands 10,11,12,13,14,15), and therefore rate low for this function. However, the wetlands associated with the Lake Reba/Miller Creek detention facility (Wetlands 3, 4, 5, 6, 7, 8, 9 and A1 associated with Lora Lake) present substantial opportunity for moderate to high water quality functioning, given the hydrologic connectivity of the wetlands to one another, the introduction of untreated stormwater into the complex, and the slope and depressional landscape positions which this wetland complex occupies. Direct evidence of the wetlands performing trapping functions was observed in the field, especially in Wetlands 3, 4, 5, and 6, where evidence of sediment build-up was apparent. In addition to the Lake Reba wetland complex, other wetlands in this area (A1, FW5, FW6) receive untreated storm runoff from streets, lawns, or farmland, and provide biofiltration functions directly related to water quality conditions in Miller Creek, and were rated moderate to high for this function (FW5 and FW6 rated moderate, while A1 rated high because of…
