Before we ever see water in Deer Creek, most of it has rained, snowed, and been stored in NID’s Mountain Division and PG&E Lakes. It’s moved from lake to lake, going through multiple powerhouses, generating electricity. It enters Scotts Flat Lake where swimmers, motor boaters, and fisherman enjoy it. Flowing into Lower Scotts Flat Reservoir, human or wind-powered boaters recreate on it.
Another portion of water entering Deer Creek comes from the watershed. A watershed is an area of land that channels water to a low point, such as a stream, river, lake, or ocean.
History of Water Management in Nevada County: 1850 Water Business is Born
Placer miners needed water for rockers; hydraulic miners needed it to move mountains.
The first miner’s ditch, to which PG&E traces its tap root, was built in 1850 by The Rock Creek Water Company. Historians locate this ditch is near Coyote Hill. Constructed by Charles Marsh, William Crawford, John & Thomas Dunn, and C. Carol at a cost of $10K, the ditch was nine miles long.
After only two weeks of operation, The Rock Creek Water Company investment paid off.
Successful, and profitable, water transportation soon spread to neighboring counties— Placer, Eldorado, Amador, Calaveras, Stanislaus, and Tuolumne County.
Before water management, Deer Creek was seasonal.
An 1854 drought caused local economic hardship. Mines stopped working, miners couldn’t pay debts, and real estate values crashed.

After assessing the lakes in the Yuba Watershed, water companies understood that gravity and elevation would work in their favor. They built systems to move water to the mines using flumes, tunnels, high-pressure pipes, siphons, and trestle bridges.
The water transportation system was an engineering marvel of its time.
Early engineers and savvy businessmen realized the potential of a year-round water supply for ranching, mills, and establishing towns.
When the Sawyer Decision washed-up hydraulic mining in the mid 1880s, the South Yuba Water Company, and its subsidiary, the Central California Electric Company, was poised to capitalize on a new industry—hydroelectrisity.

“There’s very little natural water in Deer Creek,” says Les Nicholson, retired Nevada Irrigation District Hydroelectric Manager.
Burlington Ridge, the apex of the North and South Fork of Deer Creek isn’t high enough to maintain a snowpack (4,160 ft elevation).
“Most Deer Creek water is imported,” Nicholson says. “Imported water means it comes from another drainage.”
In Deer Creek’s case, that drainage is the Yuba Watershed.
Nicholson generously shared his time to explain the complicated route water takes before we see it in our ditches, creeks, and rivers.

Run-off and gravity always show the direction water is flowing.

Nevada Irrigation District
Since 1921 the Nevada Irrigation District has supplied domestic, irrigation, and domestic water for Nevada and Placer Counties. It is an independent California special district governed by an elected board.
