By all means, allow boats.. Even private boats.
SF still needs to filter the water. Guess what everyone has done along the Tuolumne river for years. It all washes down.
I'd rather see the valley restored and even if it becomes Yose valley North, It would be better managed in that form.
Don Pedro is big enough to take the water; at least we get a valley back.
They can leave the dam and still allow water to be released after a bit of engineering.

Hetch Hetchy was built before the downstream dams. The water went directly to San Francisco, and was not required to be treated, which saved SF money. As an untreated water source they did not want people swimming or boating in it. That rationale is now a moot point, because the water now goes through Don Pedro which does allow boating including motor boating. I do not know exactly when, but at some point, water treatment was required regardless of boating on Hetch Hetchy or not. Some reservoirs are privately owned and the owner can set their own rules. Don Pedro is a federally funded dam/reservoir. I believe Hetch Hetchy is still private (correct me if I am wrong).
No. The Hetch Hetchy Aqueduct passed beneath Don Pedro Reservoir with no connection to the lake. The water in Hetch Hetchy Reservoir is delivered to Bay Area Customers directly from Hetch Hetchy through 150 somthing miles of tunnels and pipes including a pipe suspended on a bridge over SF Bay, with no filtration, just some chlorination. Don Pedro is owned by a regional irrigation district and is not part of the Hetch Hetchy system.

Thanks for that correction. It makes sense.
