• D. Consider Recommendation on Adoption of Resolution
• No. 16‐26 Authorizing Filing of Water Use Amendment

Application Regarding Overdrafting Lake Lavon for the East Fork Wetland Project When Water Cannot Be Pumped to Lake Lavon (Please refer to Administrative Memorandum No. 4654)

Agenda

• East Fork Water Rights Tied to Daily WWTP Discharges
• USACE Operational Protocol for Lake Lavon Preclude

Moving East Fork Water when Lavon in Flood Stage

• Water Right Application Seeks Rights to Account for

Water Used Against East Fork Water Right when Lavon in Flood Pool (Above Elev. 492’)

• Staff and Consultants added sources after agenda was

posted

East Fork Spill Credit

“Recommend to the Board of Directors tabling the action included on today’s Board agenda (May 26, 2016) with:

• Direction for staff to include additional water supplies in

the water right amendment application, and

• Recommend to the Board of Directors adopting a

Resolution at the June 2016 Board Meeting, authorizing the filing of an application with the TCEQ to secure the right to overdraft Lake Lavon whenever:

– the elevation of the Lake is above elevation 492’ mean sea level and water cannot be transported to Lake Lavon from the East Fork Wetland, or – from the District’s supplies in the Sabine River Basin or – supplies made available through the Main Stem Pump Station.”

East Fork Spill Credit

II. ACTION ITEMS

• E. Consider Recommendation on Adoption of Resolution
• No. 16‐25 Authorizing Filing of Temporary Water Use

Permit Application Regarding Overdrafting Lake Lavon for Three‐Year Period (Please refer to Administrative Memorandum No. 4653)

Agenda

• New Water Supplies are Delayed for a Number of

Reasons

• A Temporary Permit May be Granted to Assist with

Water Rights

• 3 Years is the Maximum Term TCEQ May Grant
• Similar Permit was Granted for Loss of Texoma

Executive Director and Staff Recommend Adoption of Resolution No. 16‐25 Authorizing Filing of Temporary Water Use Permit Application Regarding Overdrafting Lake Lavon for Three‐Year Period

3‐Year Temporary Overdraft

II. ACTION ITEMS

• F. Consider Recommendation on Adoption of

Resolution No. 16-27 Authorizing Filing of Amendment to Water Right Regarding Overdrafting Lake Lavon in Lieu of Transporting Water from Lake Texoma or Chapman Lake (Please refer to Administrative Memorandum

• No. 4655)

Agenda

• NTMWD's Existing Water Rights Permit Overdraft Lavon

Under Certain Conditions 1) Lavon in Flood Pool & "Spilling“ 2) Ray Hubbard Above 435.5' & "Spilling" 3) Downstream Flows

• USACE Does Not Always Release Flood Waters From Lavon
• DWU Does Not Always Allow Water to Rise Above 435.5‘
• Idea is to Permit the Claiming of "Spill Credit" on Lavon

Water Elevation Only

Modify Existing Overdraft Rights

Executive Director and Staff Recommend Adoption of Resolution No. 16-27 Authorizing Filing of Amendment to Water Right Regarding Overdrafting Lake Lavon in Lieu of Transporting Water from Lake Texoma or Chapman Lake

Modify Existing Overdraft Rights

II. ACTION ITEMS

• G. Consider Authorizing Reallocation of Funding for

Construction Manager At‐Risk Construction Services on Project No. 269, Trinity River Main Stem Pump Station and Raw Water Pipeline (Please refer to Administrative Memorandum No. 4671)

Agenda

MSPS CMAR

• April 2015 ‐ Board authorized an initial appropriation of $41 million to

fund the project.

• June and October 2015 ‐ Board authorized execution of contract

amendment(s) for procurement, construction packages, and CMAR construction services.

– Maximize use of the $40,120,541 funding available for the project – Purchase of approximately 18 miles of 72‐inch pipe – Construction of weir box within wetlands property

• Balance for the project to be funded upon approval of the GMP and bond

sale in April 2016

– Bond sale for MSPS portion was $70,000,000 – GMP of $103,500,000 – Tabled by the Water Committee

MSPS CMAR

• Two major challenges facing the project team

– Manufacturing and delivery of pipes – Keeping CMAR team productive and intact

• Manufacturing and delivery of pipes

– Delivery of the pipes scheduled for last week of June 2016 – Stopping production can lead to extended delays and additional costs – Ad Memo No. 4671 to reallocate funds to facilitate delivery of pipes on project site – No additional funding required for the project

• Keeping CMAR team productive and intact

– Allow the CMAR to construct a new weir box to improve metering – Work is required regardless of wetlands property issue outcome – Work coordinated between Lewis Isaacks and Rosewood Properties – Provides sufficient work for the CMAR team to keep intact

Executive Director and Staff recommend authorizing reallocation of funding for Construction Manager at‐Risk Construction Services for Project No. 269, Trinity River Main Stem Pump Station and Raw Water Pipeline

MSPS CMAR
