pH = deep water: 7 ppm
shallow water: greater than 8 ppm
Phosphate = less than .2 (x4.4) ppm
Stream Depth:
Point A = .12m
Point B = .53m
Point C = .32m
Point D = .23m
Average Stream Depth = A + B + C + D = .30m

Volume of Flow = wdvc
w = width
d = depth
v = velocity
c = constant (.8 for rubble bottom or .9 for mud or sand bottom)
Time at A = 17 sec.
Time at B = 18 sec.
Time at C = 17 sec.
Time at D = 20 sec.
A + B + C + D = 18 Average Time

Stream Velocity = 5m = .28 m/sec.
Average Time
Gallons/second = 264 x .4364
Gallons/minute = gallons/sec.
60
Gallons/sec. = gallons/sec.
3,600
Gallons/day = gallons/sec.
86,400
Average Person in the United States uses 200 gallons of water per day.
