<br />137 feet. The conduit dimensions for the inlet side are
<br />4'8" x 4'8" with stainless steel lining and the outlet side
<br />varies from 4'8" X 4'8" to 8' X 13' with no lining. The eleva-
<br />tions of the inverts at the inlet and outlet are 4764.0 and 4751.0
<br />feet msl, respectively. The conduit is controlled by three gates~
<br />One 7' X 8' bulkhead gate and two 4' X 4' high-pressure gates in
<br />tandem. The conduit discharges into the river channel and has
<br />a maximun discharge of 1,350 c.f.a. when the pool elevation is
<br />4919.0 feet mal. However, the recommended maximum is l,l20
<br />c.f.s. The river outlet works discharge curves are shown on
<br />Plate 2-6.

<br />(2) Spillway Outlet Works. The spillway outlet
<br />works consists of three gated conduits, which are located in
<br />buttresses 9, II, and 13, under the spillway. Each conduit is
<br />l35 feet long and discharges into the stilling basin, then
<br />through ,the outlet channel into the river. The inlet side of
<br />each conduit is 6' x 6' 6" with ateel plate lining and the outlet side
<br />of each conduit varies from 7' X 9' to 12' x 18' with no lining.
<br />The elevations of the inverts at the inlets and outlets are
<br />4765.0 and 4748.1 feet mal, respectively. Each conduit is
<br />controlled by three gatesl One II' x 27' bulkhead gate and
<br />two 6' x 6'6" high-pressure gates in tandem. The lIl8)Cimwn dis-
<br />charRe from the spillway outlet worka is approximately 9,900
<br />c.i.s. at pool elevation 4919.0 feat mal. However, the recom-
<br />mended maximum discherge is 8,190 c.f... The spillway outlet
<br />works discharge curve. are shown on Plate 2-7.

<br />(3) Fish Hatchery Outlet Works. The fish hatchery
<br />outlet works is located in buttress number 8. The outlet works
<br />is a gated and valved 3D-inch-inside-diameter steel pipe with
<br />multilevel intakes. The elevations of the inverts at the inlets
<br />are 4761.8, 4785.8, 4809.8, and 4849.8 feet mal. Each of the
<br />two lowest inlets is controlled by two 30-inch butterfly valves
<br />in tandem and the same 5'4" x 6'4" bulkhead gate. Each of the
<br />remaining inlets is controlled by two 30-inch butterfly valvee
<br />in tandem. The outlet works will supply water at a maximum
<br />rate of 30 c.f.s. and control the water quality to the fish
<br />hatchery to be constructed downstream of the dam.

<br />(4) South Outlet Works. The south outlet works
<br />is located in buttress number 7. The outlet works consists of
<br />a gated and valved single-level intake conduit and a gated and
<br />vslved multilevel intake conduit. Both conduits are 48-inch-
<br />inside-diameter steel pipe. The single-level intake conduit
<br />is controlled by one 8'7" x 8'10" bulkhead gate snd one 48-inch
<br />hutterfly valve with an invert elevation of 4766.5 feet mal.
<br />The three inlets of the multilevel intake conduit are controlled
