Novato Creek is a stream in eastern Marin County, California, United States. It originates in highlands between Red Hill and Mount Burdell above the city of Novato, California, and flows before emptying into San Pablo Bay south of Petaluma Point. ==History== Miwok and Pomo people were the earliest residents of the watershed. Olompali, the site of a significant Miwok village, is located at the southern base of Mt. Burdell. In 1839 Mexican land grants established Rancho Novato. Grazing brought a host of invasive annual grassland plants that eventually dominated the deep-rooted native perennial grasses and altered runoff rates. By 1856 extensive apple orchards occupied the valley floor and many of the creeks had been channelized for irrigation. The tidal marshlands had also been diked and drained for agriculture (primarily oat-hay production) by the middle of the nineteenth century. In the 1880s the creek was dredged to make way for schooners bound for San Francisco. Novato, one of the four townships in existence when Marin County formed in 1850, was incorporated in 1960. Ground was broken for Hamilton Air Force Base in 1932 and dedicated in 1935 (the base was decommissioned in 1974, and designated as a historic district in 1988).〔 Land use changes have increased sediment supply and decreased sediment transport, causing the lower reaches of Novato Creek to become shallower. In addition, the construction of Stafford Dam (starting in 1952) increased its drainage area by .〔(【引用サイトリンク】title=Geomorphic Studies by Laurel Collins )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Novato Creek」の詳細全文を読む スポンサード リンク
