In my quest to find why we use so much water for domestic needs, I
measured our shower head output this morning. It measured exactly
2-gallons in 1-minute. Seems high. What is the recommended flow rate
for water conservation?

The water conservation issue is a hoax. First, there is plenty of
water in the world. Second, more is being made every day as a result of
fossil fuel combustion. Third, using water in toilets and laundry
machines doesn't destroy it. Fourth, by putting water in your septic
system or sewer, you are returning it to nature. Evaporation, cloud
formation, precipitation, collection and use continue the cycle.
