Lahontan cutthroat trout (LCT) is the only trout species native to Fallen Leaf Lake, Lake Tahoe and the Truckee River Basin but were extirpated by introduction of predatory non-native lake trout ( Salvelinus namaycush), other competing non-native salmonids, and overfishing. The wetland is also historic habitat for Sierra Nevada yellow-legged frog, as well as Lahontan cutthroat trout ( Oncorhynchus clarki henshawi), a threatened species listed on the Endangered Species Act. In addition to man-made alterations, such as an access road that runs north-south in the middle of the wetland, the influx of aquatic invasive species, such as Eurasian watermilfoil ( Myriophyllum spicatum), bull frogs and warm-water fishes have invaded both Tallac and Taylor creeks, which now compete with native species such as Lahontan tui chub ( Gila bicolor pectinifer), Lahontan redside shiner ( Richardsonius egregius), Tahoe sucker ( Catostomus tahoensis) and Tahoe yellowcress ( Rorippa subumbellata). From historic aerial photos, it appears that these swales may have hydrologically connected Taylor and Tallac creeks and follow topographic features such as historic beaches/lake levels. The valley between Taylor and Tallac creeks is dissected by a series of east-west historic lagoons (or swales) that created wetland habitat for a variety of native animal and plant species. Historically, these two wetland complexes provided approximately 400 acres of wetland and meadow habitat. Taylor and Tallack Creeks form an important wetland complex separate from Lake Tahoe by Baldwin Beach. From here it winds its way northwards, entering the Tallac & Taylor Creek wetland before entering Lake Tahoe. Taylor Creek is the only outflow for Fallen Leaf Lake, and begins at a spillway on the Fallen Leaf Lake dam on the north side of the lake. Taylor, who homesteaded 160 acres near the creek in 1864. Taylor Creek is probably named for Elijah W. To the Washoe people, Taylor Creek was known as Dawgašašíwa It was a significant Washoe Indian camping and fishing site. Taylor Creek is a 2.2-mile-long (3.5 km) northward-flowing stream originating in the Fallen Leaf Lake and culminating at Baldwin Beach at Lake Tahoe, about 1 mile (1.6 km) west of Camp Richardson in El Dorado County, California.
