They didn't have big equipment like so they would run a pipe up hill into a dammed up spot in the river and the pressure would wash away the banks of the hill and leave the heaver gold then they would sluice it and pan it they were able to move allot of earth that way and scared the land.

Why was hydraulic mining in the mid-80s started?
Hydraulic mining in the mid-1800s was primarily initiated during the California Gold Rush as a method to extract gold from riverbeds and hillsides. This technique involved using high-pressure water jets to dislodge soil and rock, allowing miners to access gold buried deeper than traditional methods could reach. The promise of substantial gold yields drove many to adopt this method, leading to its widespread use despite eventual environmental concerns and regulatory restrictions.
How does hydraulic mining work?
Hydraulic mining is a technique used to extract gold and other minerals from soil and rock by using high-pressure water jets. The process involves directing a powerful stream of water onto the surface of the mining site, which erodes the soil and dislodges the desired materials. The slurry created is then collected and processed to separate the valuable minerals from the sediment. This method was particularly popular during the California Gold Rush but has since faced environmental concerns due to its impact on landscapes and waterways.
What was the advantage of using hydraulic mining when mining for gold in the gold rush?
After the hydraulic giant was invented with a balance system to allow one operator to manage it, many large low and medium grade deposits of gold became feasible to mine. Heavy Equipment was extremely expensive to operate and to power, not to mention maintenance. If adequate water was in the vicinity preferably moved by gravity hydraulic mining could become profitable. If was cheaper if the water pressure was generated by gravity through a stream dammed and piped to the working face rather than by mechanical pumps due to cost. Other considerations were a area usually a river to dump the tailing's in a gouge or steep valley also works but most always lead to a river. Hydraulicking the ground was also used to remove overburden or barren ground so hydraulicking was employed to remove this layer and expose the gold bearing gravels below. Many hydraulic mining operations both large and small were forced to shut down by changes in mining laws and WWII as there was a ban on mining except for select metals and minerals shut all of the operations down the majority of which never restarted. The areas where work stopped are good areas to employ metal detectors today as the hydraulic nozzles had tremendous amounts of force but only at the nozzle contact are and directly below. The hydraulicked floor of the pit or "cut" would wash a fair amount of the fine gold down but unless thoroughly cleaned of all pay would permit larger coarser gold to settle near the surface hidden.

How many types of mining where there in the California gold rush?
During the California Gold Rush, there were primarily three types of mining techniques employed: placer mining, hard rock mining, and hydraulic mining. Placer mining involved extracting gold from riverbeds and stream deposits using simple tools like pans and sluices. Hard rock mining targeted gold embedded in solid rock, requiring more complex equipment and techniques. Hydraulic mining used high-pressure water jets to erode soil and expose gold, but it also led to significant environmental damage.
