Title

Milburn Pond Isolation Project

Description

The project site is bounded by the San Joaquin River to the north and the City of Fresno to the south. The project would isolate the abandoned gravel pit known as Milburn Pond from the San Joaquin River channel to increase native fish survival by reducing movement of non-native warmwater fish species from the pond to the river and movement of native salmonids from the river to the pond. This would be accomplished by modifying the existing berm to fill existing breaches, strengthen weaker berm sections, and raise elevations of low-berm sections to minimize the potential for future breaches. Other improvements would include constructing an equalization saddle with modified French drain within the berm to equalize Milburn Pond with the river during flow fluctuations and creating a high-flow side channel. In addition, rock slope protection and biotechnical erosion protection would be installed to minimize erosion, and an existing access route along the southern and eastern boundary of Milburn Pond would be improved. North Milburn Avenue adjacent to the site may need to be raised approximately 1 foot in low areas to avoid premature overtopping during flood releases from Friant Dam.
