Channel 12 NewsTISHOMINGO, Okla. -- One Oklahoma river is rising to unprecedented levels and others are experiencing major flooding following

a torrent of rain from TD Bill.

The National Weather Service predicts the Washita River near Dickson will crest Thursday night at an all-time high of just over 47

feet.

That's more than 20 feet above flood stage.

The river is projected to rise about 27 feet over a 24-hour period.

The service issued a flood warning for the area saying "catastrophic flood depths are expected to wreak havoc in the Washita River

valley."

More than 10,000 acres of farmland has been flooded and transportation to homes in the area could be cut off for days.

16,400 surface acre water supply lake in Fannin County

Near-term water supply for the growing urban population

north and east of Dallas-Fort Worth metroplex

Clean Water Act Section 404 permit required from the

USACE for construction of the dam

Due to scope and magnitude of potential impacts, an

Environmental Impact Statement (EIS) is being required

Highly cooperative and responsive applicant

Public Notice and Scoping Meetings generated numerous

comments from the affected public and Federal and State

agencies in opposition to the project

Identified concerns are evaluation of alternatives, demand

projections vs conservation/reuse, socio-economic impacts,

terrestrial and aquatic wildlife and resources impacts,

historic/cultural properties, and aquatic resource mitigation

Draft EIS released February 2015 generated similar comments

EPA rated the Draft EIS as a “3 – Inadequate” in June 2015

Evaluate comments, re-examine alternatives and

potential impacts, and revise EIS, in accordance with

procedures in Nat’l Environmental Policy Act (NEPA)

Complete functional assessment of wooded wetlands

Refine the Aquatic Resources Mitigation Plan

- NTMWD has proposed aquatic ecological restoration

as mitigation on portions of 15,000 ac ranch at Bois d’Arc

by ASA (CW) Darcy for construction in FY15

• Cutoff Wall is near completion and should be

•Steel pipe liner has been delayed until summer

2016 to take advantage of the low flows during

Concerns

• Void around the conduit

• Loss of material through the conduit joints

• Loss of material at the downstream exit face

• Hydraulic fracture within the embankment

Way Ahead

• Construct downstream filter and chimney filter.

• Construct the steel pipe liner Summer 2016.

• Interim Risk Assessment will begin in Sep 2016

• Reassess dam with modifications in

Become filled with sediment necessitating the need

Way AheadStrategic Alliances and Sponsor: Waurika Lake

Master Conservancy District

Actions/Funding Requirements:

FY2015: $50,000

The Waurika Lake Master Conservancy District (WLMCD)

requested Section 408 authorization to restore Lake Waurika’s

dependable water volume yield of the conservation pool and

improve raw water quality in April 2015

After District agency technical review, the WLMCD’s request was

approved pursuant to Section 14 of the Rivers and Harbors Act

of 1899, 33 USC 408 on 14 July 2015. This authorization was

imperative for significantly increasing the dependable water yield

to the conveyance system and improving the water quality for

community members serviced by the WLMCD
