The Solano Projects are much more than just Monticello Dam and Lake Berryessa, including Putah Diversion Dam, Lake Solano, and the Putah South Canal. Lake Berryessa is the largest body of water formed from the Solano Projects and so is the most well-known. [11] Lake Berryessa does help to manage flooding in Yolo county.
Within Excel, the goal seek function can be used to set column 15 to 0 by changing the depth estimate in column 2 instead of iterating manually. Table 1: Spreadsheet of Newton Raphson Method of downstream water surface elevation calculations Step 5: Combine the results from the different profiles and display.
Water spills over its lip when the lake reaches 1,602,000 acre-feet (1.976 km 3) and a reservoir elevation of 440 feet (130 m) above sea level. The last time the reservoir spilled through the glory hole was on February 10 2025, [ 16 ] previously a natural spill occurred on the afternoon of February 26, 2019.
Stream gradient may change along the stream course. An average gradient can be defined, known as the relief ratio, which gives the average drop in elevation per unit length of river. [4] The calculation is the difference in elevation between the river's source and the river terminus (confluence or mouth) divided by the total length of the river ...
See photos of Lake Berryessa's Glory Hole . Commonly called the "Glory Hole" by residents and tourists in the area, the spillway is officially called the "Monticello Dam Morning Glory Spillway ...
The dam and lake are part of the United States Bureau of Reclamation's Solano Project and was completed in 1957. [15] The project's purpose is to provide water for irrigation, though it also supplies municipal and industrial water to major cities in Solano County. About 32,000 acre-feet (39,000,000 m 3) is provided by the project annually.
Discharge as a function of water surface elevation for NRCS and USBR formulas. For the NRCS computations, the mean velocity of approach was assumed to be zero. For the USBR computations, it was assumed that linear interpolation could be used to obtain C from H. For a given depth at the spillway crest, the flows calculated using the USBR method ...
The above groundwater flow equations are valid for three dimensional flow. In unconfined aquifers, the solution to the 3D form of the equation is complicated by the presence of a free surface water table boundary condition: in addition to solving for the spatial distribution of heads, the location of this surface is also an unknown. This is a ...
