<br />Water Supply Forecasting
<br />
<br />The NRCS administers the cooperative snow survey
<br />program in cooperation with other federal, state, and
<br />local agencies as well as private organizations and
<br />individuals. The NRCS publishes a monthly account-
<br />ing of snowpack values and basin water contents.
<br />These monthly reports are available December 31
<br />through May 30 each runoff season. This infonnation
<br />is gathered from snowlel reporting stations. This
<br />information and data is beneficial to flood forecasters
<br />and flood emergency operations.

<br />3.2.4.3.1 U,S. Army Corps of Engineers
<br />
<br />The Corps of Engineers is involved in developing and
<br />implementing plans for flood control, navigation, hy-
<br />dropower, recreation and water supply. The corps
<br />also has authority for emergency operations, bank
<br />protection, permtt administration, and technical assis-
<br />tance. Corps programs in Colorado can be lumped
<br />into five different authorities: 1) Feasibility Studies and
<br />Projects; 2) Continuing Authority Projects; 3) Emer-
<br />gency operations; 4) Floodplain Management Ser-
<br />vices; and 5) Permtt Issuance.
<br />
<br />Feasibility Studies and Projects
<br />
<br />Congress can authorize the corps to perform feasibility
<br />studies that may resutt in projects for flood control,
<br />navigation, hydropower, water supply, and recreation.
<br />
<br />The Albuquerque. District has completed seven pro-
<br />jects in the Arkansas River Basin. They are: John
<br />Martin Reservoir, Trinidad Lake, Pueblo Floodway
<br />Levee Extension, Templeton Gap Floodway, Holly
<br />Levee System, Wolf Creek Project, and Las Animas
<br />Flood Control Project. There is one project in the Rio
<br />Grande River Basin, the Willow Creek Channel Im-
<br />provement. In addition, the corps under the Small
<br />Flood Control Project Authority constructed the Pinon
<br />Canyon Dam.,
<br />
<br />The Albuquerque District has a feasibility study of
<br />Fountain Creek-North of Pueblo in the reconnaissance
<br />stage and a study of Fountain Creek at Pueblo in an
<br />advanced engineering stage. The district also has
<br />studies in the advanced stages under the authorities of
<br />Arl<ansas River and Tributaries and Rio Grande and
<br />Tributaries.
<br />
<br />The Omaha District has three existing reservoir pro-
<br />jects in the South Platte River Basin: Cherry Creek
<br />Lake, Chatfield Lake, and Bear Creek lake. The
<br />Omaha District has also constructed a detention dam
<br />and reservoir in Aurora under the Small Flood Control
<br />Project Authority. A channel improvement project on
<br />the South Platte River below Chatfield Dam is cur-
<br />
<br />e
<br />
<br />rently in the construction phase.
<br />
<br />The Sacramento District is currently engaged in a
<br />study under the authority of the Colorado River and
<br />Tributaries above Lees Ferry.
<br />
<br />Continuing Authorities
<br />
<br />The Corps of Engineers has discretionary authority to
<br />implement certain types of water resource projects
<br />without congressional authority. These projects are
<br />typically Iimtted in scope and cost. Applicable continu-
<br />ing authorities projects and federal cost limitations are
<br />section 14: Emergency streambank Protection of Pub-
<br />lic Faciltties - $250,000; Section 205: Small Flood
<br />Control Project - $4 million; and Section 208: Snag-
<br />ging and Clearing for Flood 'Control - $250,000.
<br />
<br />The Albuquerque District completed four Section 14
<br />Emergency Stream bank Protection Projects in 1984.
<br />They are located at: 1) Fouritain Creek at Security; 2)
<br />Fountain Creek at strabnore; 3) Interstate 25 in Col-
<br />orado Springs; and 4) Four Mile Creek in Canon City.
<br />The Albuquerque District has four addttional Section
<br />14 investigations underway during 1984 in the
<br />Arl<ansas River Basin. The Omaha District had twelve
<br />Section 14 investigations underway during 1984 in the
<br />South Platte River Basin to determine if any stream-
<br />bank protection projects are feasible.
<br />
<br />Emergency Operations
<br />
<br />Under the provisions of Public Law 84-99, the corps
<br />has the authority to respond to flood emergencies.
<br />The authority includes flood fighting, constructing ad-
<br />vance measures (temporary) in anticipation of immi-
<br />nent flooding, and repair of damaged flood control
<br />works after the flood event.
<br />
<br />In 1964, the Sacramento District Corps was involved
<br />in floodlight activities in the communities of Silt, Grand
<br />Junction, Gunnison, Olathe, and Delta, Colorado.
<br />These activities consisted of providing sandbags, pro-
<br />viding rock for erosion protection, and constructing
<br />emergency levees at an estimated cost of $155,000.
<br />The corps operated an Emergency Operations Office
<br />in Grand Junction with a 12-person staff in May. The
<br />corps provided inspectors for for Damage Survey
<br />Teams. It also provided floodlight assistance, engi-
<br />neering expertise, flood drainage assessment, and
<br />advice on applicable corps programs. In summary,
<br />the corps emergency activities in Colorado during
<br />1984 involved about 25 personnel over several months
<br />of on-stte visits totaling about 350 man-<iays.
<br />
<br />Floodplain Management Services
<br />
<br />The corps can provide assistance in evaluating flood
<br />hazards to a stte, floodplain delineation, and technical
<br />assistance and guidance in wise floodplain manage-
<br />ment. To date, the corps has completed a total of 48
