I am not an expert on mining law - I am just trying to help. Use the information in this website at your own risk. See the Notice at the bottom of this page.
The water intake must be screened - see below.
In April 2016, Information Update No. 38 was published - Acceptable Practices for Placer Hand Mining in British Columbia.
Rule 6 made the 1.5 Inch Pump Rule official. It is about sluice boxes and highbankers, and using small portable water pumps. The rule ends...
Size of pumps shall not exceed a 38 mm (1.5 inches) suction intake.
If you have a 2-inch pump and really don't want to buy another one, you might want to contact the appropriate Regional Mining Office. Or maybe Mineral Titles. One of them may be able to help. Or maybe not - they may say that you must apply to use the pump.
The water intake must be inside a screened box or bucket. It may be weighted so that it sits on the stream bottom. The screens should be at least 12 inches above the stream bottom.
The screening requirements are the: Freshwater Intake End-of-Pipe Fish Screen Guideline from the Department of Fisheries and Oceans (DFO).
Pumping water from a watercourse is governed by the Water Sustainability Act, which came into force February 29, 2016.
There is a government Water Sustainability Act Home Page.
The Environment Ministry has its Water Sustainability Act main page.
if you plan to pump water, and you need a bigger pump or you do not qualify as a Hand Miner, you must apply for...
To get a water licence, it may be necessary to do a Notice of Work application to obtain a Reclamation Permit, even if you don't otherwise need one.

For a machine-digging operation, these are not large costs. For a modest hand-digging operation, these are significant costs, possibly comparable with the other major out-of-pocket expense - travel expenses.
|1 US gallon||= 3.785 Litres||so 50 gal||x 3.785||= 189 L|
|1 Imperial gallon||= 4.546 Litres||so 50 gal||x 4.546||= 227 L|
|1 Imperial gallon||= 1.2 US gal||so 50 Imp gal||x 1.2||= 60 US gal|
1 Cubic Metre ("m3") = 1000 L = 220 Imp gal = 264 US gal
|Pump Size||US gal/min||Litres/min||cubic metres/hr|
|1.5 inch||50 to 100||200 to 400||12 to 24|
|2 inch||100 to 200||400 to 800||24 to 48|
The stated capacity was 74 gpm which is 280 L/min
280 L/min / 1000 l/m3 = 0.28 m3/min
0.28 m3/min x 60 min/hr = 16.8 m3/hr
If you know the conversion factor, but you don't know whether you should multiply or divide, first decide whether the result is going to be larger or smaller than the starting number.An individual small-scale placer miner might run the pump at 1/3rd to 2/3rds capacity - 6 to 12 m3/hr.
At 5 hrs/day: 6 m3/hr x 5 hrs/day = 30 m3/day to 12 m3/hr x 5 hrs/day = 60 m3/day
At 10 hrs/day, double those to 60 to 120 m3/day
