In 2011, construction began to build a new dam here and today crews reached a major milestone. They completed the spillway, an important safety feature, to control the release of water from the reservoir which it had to be kept at a low level because the old dam wasnt quake safe. Thats the biggest reservoir in the bay area right here locally. And so bringing it back to full capacity means that extra water supply in drought. But building the new dam has not been smooth sailing. The final project has been delayed three years and will cost a whopping project. Crews discovered several ancient landslides too unstable to build on so the dam had to be redesigned. Another challenge, making sure the asbestos in the rocks here doesnt pose a concern to workers and the public. The San FranciscoPublic UtilitiesCommission Says the additional costs will not be passed on to customers. Construction of the entire dam is expected to be completed in spring 2019.

The International Olympic committee is now sending two of its top officials out to help them whip themselves into shape. They got it done. Do not call it pingpong. This will be the second trip to the olympics for this woman and shes coming clean on how she discovered the sport. Heres joe rosato jr. Reporter a faculty laundromat is where she tumbled into the sport. My dad was a professor there. Any time i did laundry, there was a table there and i played with my parents for fun. Reporter a future olympian was born. Soon things did get serious and she traded up from a laundry room to a tennis club. It was so fast and so physical.

Walking in the open arena, it was mind blowing. Reporter and though she didnt take home a medal, she went home with more fire for the sport. Her path winds back to the Table Tennis Center in milpitas. Long hours every day. You have to really have this gift. Reporter a lot of people dont really know the sport of table tennis. They think its pingpong where you stand in a garage and swing your arms around. Reporter along with raising the visibility of table tennis, shes inspiring other players.

Look at you now. Look at me. Across the bay area, 60s and 70s. Very comfortable but hang on. Were expecting to see another warm day, especially for the trivalleys. 83 degrees there. 80 for the peninsula and the south bay and not as hot at the coastline today. 72 degrees for San Francisco and the north bay. And thats a sign of some changes headed our way. In fact, were going to be undergoing major cooling as we head towards the weekend. Today, still warm across the trivalley, south bay, widespread 80s. The north bay and coastline, San Francisco down through the peninsula, youll see 70s today. The 70s move towards the trivalley tomorrow and towards the south bay and then youll see San Francisco back into the 60s tomorrow and look at this, were not done there just yet. 50s at the coastline by friday. So not the kind of weekend weve had last weekend where we had the 80s and 90s. Kind of a cool weekend coming our way. Now, we have the rip current into half moon bay, pacifica and through monterey because of the strong rip current as the storm systems make their way in and chop up the ocean. Were very excited about the sharks taking on the kings. Temperature is 72 degrees and they are in the playoffs. Go sharks. All right. Also the giants taking on the diamondbacks this evening. Temperatures are cool and comfortable. Back into the 60s. 65 degrees for first pitch. Right around 7 15. Its breezy this evening. Clouds start to return and were actually expecting to start the day tomorrow with mostly cloudy skies because of this storm system sitting off the coastline. This thing, not going to give us any rain. Its just going to cool us a little bit. The next storm system on the heels of that one, that moves in after the morning commute and its expected to be with us for at least the first half of the day. We may get another shot of rain as we head towards sunday, primarily across the north bay. It looks like we may get a trailing light showers and then as far as the computer model goes, its not believable at this point. Weve been going back and forth. The thing that is believable, the rain that is coming for friday. Were talking about a quarter of an inch for the south bay. More than that as you head towards San Francisco and even more than that, half of an inch to close to an inch across the north bay. Again, that would come friday before all of the showers wrap up friday evening. Also, sierra snow being tracked. That moves in towards sunday and monday and then were expecting to see 3 to 6 inches of new snow above 7,000 feet. Not a big storm system but give you a heads up if youre traveling that way. This weekend looks delightful, just like it in the bay area. No 80s and 90s. Not the perfect beach weather. It will be comfortable and not intolerable. Back over to you. All right. Delightful indeed. Up next at 11 00, a special look at the northern lights. And im sam brock. Cash, clinton and clooney. The star actor says most of the money he helped raise this weekend did not go to the president ial candidate. This fact check explained, next. Only on nbc bay area. Late last night we have confirmed Hillary Clinton will be returning to San Francisco for a fundraiser. But this time with a twist a low cost event. Unlike last weeks San Francisco fundraiser well, Hillary Clinton will be returning to San Francisco for a fundraiser and it will be a lowcost event. Hosted by George Clooney, it was 32,000 a ticket. This time, the tickets will start at 45 bucks. Shell be here on may 5th. Interested to see. It will be fun to see. They are trying to get big money out of politics. Thats what Bernie Sanders said, shouted outside a Hillary Clinton fundraiser with those expensive tickets. Right. That event, most of that money isnt even going to Hillary Clinton. So is that true . Sam brock has todays reality check. This home is my land reporter camping out in l. A. And San Francisco at Hillary Clintons fundraisers casting criticism at the events host, George Clooney, for flexing his hollywood might and raising cash for clinton. Clooney pushed back on meet the press. The overwhelming amount of money that were raising, and it is a lot of money, is not going to hillary to run for president. Its going to the down ticket, to the congressman and senators to try to take back congress. Reporter that claim is about half true. The rules say a person can only give up to 2700 in a president ial primary. So that money is earmarked for clinton. These are mandated rules. Daniel newman is president of a Nonpartisan Group tracking money in politics. He says the larger contribution gets divvied up among state democrat parties at least for now. If you look at the ticket prices for that George Clooney event at 30,000 and up, the majority of the money from the ticket didnt go directly to the hillary for president committee. It went to various Democratic Party committees. Vote for me on tuesday. Reporter but heres the real reality check. Those democratic parties can then spend the money right back on Hillary Clinton if she captures the nomination. Even George Clooney acknowledged were talking about obscene amounts of money here. But its also true, exclusive fundraisers aside, most of the donations raised by the Hillary Victory Fund fall in the 2 to 3,000 range, which means most of the money generated by that committee is going straight to hillary. For reality check, im sam brock, back to you. Thank you, sam. You can watch sam along with laura and chris and me and kari and mike every day. Today in the bay coverage starts at 4 30 every morning.
