<br />The District still retains and maintains the river road from Earp
<br />to Parker dam, and the branch roads to the Intake and other pump-
<br />ing plants. Construction during the period consisted of enlargement
<br />of the Gene Wash culvert on the road to the Intake pumping plant,
<br />similar work at the Copper Basin culvert on the river road below
<br />Parker dam, and relocation of a portion of the river road near Earp,
<br />The culvert work was done by District forces. The relocation below
<br />Parker dam was done by the U. S. Indian Service to remove the road
<br />from the reservoir to be formed by building of its Headgate Rock
<br />dam.

<br />The severe desert storms of September 1939 caused only moderate
<br />damage to District roads, Shoulders were eroded in spots and some
<br />surfacing destroyed, dips were filled with sand, and in the river
<br />,area_s[iqes occurr~d ~rQm pa_nl!:s, _AR d_eQr!s W,!S_CLU!ckly removed_
<br />and surfacing restored.
<br />The cost of construction and of operation and maintenance of
<br />the road system to December 31, 1939 is shown in table 8.
<br />Since Januar;' 1, 1940 the District paved roads and the unpaved
<br />patrol roads have been maintained by the regular main aqueduct,
<br />pumping plant, and transmission line forces.
<br />

<br />
<br />Tunnel construction operations on the main aqueduct were con-
<br />fined to San Jacinto tunnel, all others having been completed prior
