After weeks of stormy weather earlier this month, California's Department of Water Resources is getting a better idea of how the state's water supply may be shaping up for the coming spring and summer.The department is planning to increase certain water deliveries, which is a good sign.Water managers with the Department of Water Resources say they are "cautiously optimistic" about the state's water supply heading into the second half of the winter season.On Thursday, DWR announced that the state water project will be able to deliver 1.27 million acre-feet of water to requesting agencies in Central and Southern California. That is about 30% of the total requested water supply.At the start of winter, water managers were expecting to send just 5% of the requested water supply.Last year at this time, at the height of the state's drought, no water was projected to be delivered. The state water project is designed to deliver water from Northern California reservoirs to agencies in Southern California, the San Joaquin Valley and the Bay Area where about two-thirds of the state's population lives. Two of the state water project's largest reservoirs, Oroville and San Luis, have risen considerably in the last month, allowing water managers to plan to send more water south, while simultaneously storing enough water for people in Northern California. As of Thursday, Lake Oroville is at 63% of capacity and water continues to steadily flow in from the surrounding watershed.It should be noted that the water supply forecast for the state water project is a conservative one and does not take into account the Sierra snowpack. The statewide snowpack is at 216% of the average for Jan. 26 and 128% of the April 1 average. DWR will conduct three more snow surveys this season and use that information along with data from aerial snow surveys to potentially adjust state water project deliveries as we get closer to the spring. The final allocations will be decided in May or June.
