A major undertaking was relocating 30 miles of Southern Pacific Railroad track, which ran right through the construction site. �V��)g�B�0�i�W��8#�8wթ��8_�٥ʨQ����Q�j@�&�A)/��g�>'K�� �t�;\�� ӥ$պF�ZUn����(4T�%)뫔�0C&�����Z��i���8��bx��E���B�;�����P���ӓ̹�A�om?�W=

Shasta Dam is 883 feet thick at its base, 30 feet thick at its crest, and contains 6.5 million cubic yards of concrete weighing 15 million tons. Grown here are more than 250 varieties of crops, including the almonds, artichokes, avocados and wine grapes that make California famous for more than movie stars.

At 602 feet, Shasta at the time was the second highest concrete dam in the world (behind Hoover at 726.4 feet) and was rivaled in mass only by the gargantuan Grand Coulee Dam, then under construction on the Columbia River in Washington. Shasta Dam is 883 feet thick at its base, 30 feet thick at its crest, and contains 6.5 million cubic yards of concrete weighing 15 million tons. By August 1942, four million cubic yards of concrete (or 807 million gallons) had been placed, and by the summer of 1943, the dam was taking final shape. ��w�G� xR^���[�oƜch�g�`>b���$���*~� �:����E���b��~���,m,�-��ݖ,�Y��¬�*�6X�[ݱF�=�3�뭷Y��~dó ���t���i�z�f�6�~`{�v���.�Ng����#{�}�}��������j������c1X6���fm���;'_9 �r�:�8�q�:��˜�O:ϸ8������u��Jq���nv=���M����m����R 4 � $i�X�b��A��%F;��a������Y���D>RO�ČFb�I*AED�$OA�D�tBx,#X���9,$�I�Ȍ��"�E*��%�W;}6U�˦k���>��>�n�^m4 A��z����� bz{eK���f��w��T�zMD��+�O� g�љ���fk��)�փ�BȔ�k�鉈�m�t��Z^�Qf}$bpmL��޹�U��l�U�>�����i[�O�Z�N�rK��n�jkzv�3F�r�ljM-��}%\������joڎ~s��_]���y{�MS����窙4}����l�:8�mf�xP(�I9D�$��O�A[:��^�m�� #�S"�!�eL�$��e9�QD"1���-��G��c�%>��rNr�سƒ�'�> �-w���=�v�z\�s���{ށ���c�v\�����}^l}Fq��>����2j)��6ƽ��q�Jƅ��E�`�=6a!ܦ�H����|>,�E���('��d}�p�t����% (���k�`.���{� &� ���K:��H�u�� \���c̸�\g��k3������n�]�k��p��F�#�� ?T�Ð^��7���чG�yx\N� 10dh�P�@7kn~���(�i�l\�������VCJ5�^u�)�������?�k" ���ti��� endstream endobj 389 0 obj <>/Metadata 100 0 R/OCProperties<>/OCGs[400 0 R]>>/Outlines 132 0 R/PageLayout/SinglePage/Pages 382 0 R/StructTreeRoot 181 0 R/Type/Catalog>> endobj 390 0 obj <>/Font<>/Pattern<>/Properties<>>>/Rotate 0/StructParents 0/Trans 408 0 R/Type/Page>> endobj 391 0 obj <>stream Shasta Dam is a curved gravity concrete dam (National ID No. N'��)�].�u�J�r� Development of irrigation in the valley began on a large scale in the 1850s, following the discovery of gold that brought hundreds of thousands of people from around the world to California’s mining regions. Frank Crowe and Ralph Lowery: A Dynamic Duo After securing the bid to build Shasta Dam, Pacific Constructors Inc. turned to the engineering genius Frank Crowe to head up the construction. Water storage began in Lake Shasta in February 1944, and the last bucket of concrete was poured on January 2, 1945. When Shasta’s five-generator plant came online in 1950, the project was complete.At 602 feet, Shasta at the time was the second highest concrete dam in the world (behind Hoover at 726.4 feet) and was rivaled in mass only by the gargantuan Grand Coulee Dam, then under construction on the Columbia River in Washington. The Shasta Dam was originally called the Kennett Dam, after the name of a town that would be flooded by the rising waters of Shasta Lake. Shasta Dam offered him that challenge: he would oversee 4,700 people and the construction of the second largest concrete dam in the country.

h��U�n�0��C'ɲ-( Stretching 400 miles from north to south, the valley’s precipitation fluctuates significantly. Shasta is only one of 20 dams and reservoirs on Reclamation’s Central Valley Project, but it has been a key component from the beginning.The project did not begin with the Federal Government, but with the State of California, which long recognized the benefits to be had by connecting the thirsty Central Valley with the state’s water-rich mountains. endstream endobj startxref H�L��n�0E������'� ]�*j)#u��B���`T����>Xx㱞S��j�\ss�Nc�=�cU��fk��i�\�IH�dk�u���(�7ms>�1���B?e��н>D�ws�K�J�� t�$�'�g©)��Ÿ-����~���/[�D�@���k�O�?�>��G�Ƒ"���{�˥��U�,N�E̊��oՊ�n�1�iZ ����+�����OnFN�˩�F��X6�s��uP^$Y�^]巽�)ڡ��ιW��e�',� &k8 CA10186) on the Sacramento River above Redding, California near Shasta Lake City built between 1938 and 1945. Soon to come on board as general superintendent was engineer Frank Crowe, who had taken charge at a number of other prominent Reclamation dams: Arrowrock, Hoover and Parker among them.A crew that eventually totaled 4,700 men excavated millions of tons of granite from the hillsides and built a 9.6-mile-long conveyor belt, which operated 24 hours a day, transporting aggregate from a quarry nine miles away. Work on the dam began in 1937, and many of the same people who had worked on the construction of the Hoover Dam would be called back in to construct the Shasta Dam. 0 Then again, because most of the rain and snow falls from December through April, the Central Valley is subject to flooding in the spring or prolonged droughts. Pacific Constructors Inc. (PCI), led by the prominent Los Angeles outfit of L. E. Dixon, won the job with a bid of $36.9 million. Northern California’s Shasta Dam is a keystone of the Bureau of Reclamation’s huge Central Valley Project, which involves 35 of California's counties and two major watersheds: those of the Sacramento River on the north and the San Joaquin River on the south. �ꇆ��n���Q�t�}MA�0�al������S�x ��k�&�^���>�0|>_�'��,�G! In 1919, a plan was submitted to the governor of California, which spurred statewide interest and led to the first of a series of state appropriations to investigate ways to conserve, control, store and distribute the valley’s water. Like those larger dams, Shasta also has been the subject of criticism, especially for its impact on the winter run of Chinook Salmon  which are listed as endangered under the Endangered Species Act. Local projects undertaken by communities, irrigation districts and public utilities followed.
