Marysville: Gateway to the Goldfields

In 1842, Theodor Cordua, a German immigrant and former Prussian officer, established a small trading post and ranch he called New Mecklenburg at the confluence of the Yuba and Feather Rivers. It was a quiet agricultural outpost on the northern edge of John Sutter's vast land grant. Six years later, it would become one of the most important cities in California. When gold fever erupted in 1848, Cordua's location proved to be geography as destiny. The Yuba and Feather Rivers were the natural highways to the northern mines, and the flat ground at their junction was the last easy stop before the foothills. In 1849, Cordua sold a portion of his land to Charles Covillaud, a French immigrant who had married Mary Murphy — a survivor of the infamous Donner Party. Covillaud and his partners platted a town and named it Marysville in her honor. The growth was staggering. By 1850, Marysville had a population exceeding 10,000, making it the third-largest city in California behind San Francisco and Sacramento. Steamboats navigated up the Feather River from Sacramento, unloading supplies and passengers at Marysville's waterfront. Pack mule trains departed daily for the mines at Rose's Bar, Downieville, and the camps along the Yuba. The city became a commercial powerhouse. Hotels, saloons, general stores, banks, and express offices lined the streets. The Marysville Appeal newspaper began publishing in 1860. A Chinese community — one of the largest in California — established itself along First Street, eventually building the Bok Kai Temple that still stands today. But Marysville's prosperity carried the seeds of future problems. Hydraulic mining upstream sent millions of tons of sediment downstream, raising river beds and increasing flood risk. By the 1870s, the city had begun constructing the levee system that would define — and sometimes devastate — the community for the next 150 years.
