0.5 Gallon/Minute= 720 Gallons Per Day (Average daily water consumption is <500 gallons/day). Pumps can draw from 3-300 gallons/minute and more than one pump on at the same time in a stream can result in fish kills.
Little Browns Creek, 2010
Pumps draining water tanks do not rapidly draw down a creek and do not require coordination
with other water diversions in the stream.

RECLAIM USED WATER
“It's easy to follow the guidelines required for a no-permit system from the new California plumbing code. The system needs to have a way to switch back to the sewer/septic, not have any pooling of greywater, be discharged under 2 inches of mulch, and a few more basic guidelines.” http://greywateraction.org/projects/greywater-recycling

Weaverville Rainfall Average
If the winter rainfall is well below average reduce crop size, install rainwater catchments, use conservation techniques. Don’t truck water in to supplement. You are just robbing “Peter to pay Paul” * As of January 20th
RETHINK WATER DEMAND
RETHINK WATER DEMAND
Time stream pumping to match natural diurnal flow patterns. A single mature Douglas-fir tree can transpire (pump) up to 100 gallons of water from the soil per day. Most of this pumping occurs during the afternoon hours An acre of mature conifer forest can transpire up to a million gallons per growing season. Mountain streams flow goes down in response to soil water pumping actions (at the same time that temperatures go up).
