Some of the hydraulic mining pits employed dozens of men and covered hundreds of acres. These were major mining operations and obviously they were finding a lot of gold. There are also small hydraulic operations that are only an acre or less in size. They have have used just a small amount of water from a creek and may be overgrown with brush and trees now.

Open-pit mining - Wikipedia

Open-pit mining is to be considered one of the most dangerous sectors in the industrial world. It causes significant effects to miners health as well as damage to the ecological land. Open-pit mining causes changes to vegetation soil and bedrock which ultimately contributes to changes in surface hydrology groundwater levels and flow paths.

Hydraulic Mine Pit areas often contain good prospects for small-scale mining. Check the exposed bedrock floor (representing the exhumed channel base) surfaces both for cracks and weathered. cemented gravels. Gold may remain in small fractures and cracks in the bedrock.

Environmental Risks of Mining

Open pit mining. Open pit mining where material is excavated from an open pit is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations which increases the amount of ore needed to be mined.

Hydraulic mining - Wikipedia

By the early 1860s while hydraulic mining was at its height small-scale placer mining had largely exhausted the rich surface placers and the mining industry turned to hard rock (called quartz mining in California) or hydraulic mining which required larger organizations and much more capital. By the mid-1880s it is estimated that 11 million ounces of gold (worth approximately US$7.5 billion at mid-2006 prices) had been recovered by hydraulic mining in the California Gold Rush.
