• Reclamation holds 205 water rights (east of Divide) • Heavily involved in the ongoing adjudication – Currently working in 11 basins (involved in 30 basins +/-) – Addressing/Resolving Issue Remarks – Addressing/Resolving Objections • We successfully negotiate settlements on 99% of claims we object to. Water Contracting

• Administer 238 water related contracts (east of Divide) – Construction Repayment Contracts – Operation & Maintenance Contracts – Dam Safety Repayment Contracts – Water Service Contracts – Loan Program Repayment Contracts • Water marketing availability (east of Divide) – Canyon Ferry Reservoir – Tiber Reservoir Recent Development Interest

• Tiber Irrigation Project – 100,000 acres +/- in Liberty, Hill, Choteau Counties – 225,000 acre-feet of water +/- • Canyon Ferry Irrigation Water Users Association – Smaller portion of proposed Avalanche Irrigation Project – 2,700 acres +/- in Broadwater County – 8,000 acre-feet of water +/- • Fresno Dam – Storage Increase – Milk River Joint Board of Control (8 Districts) – Exploring in conjunction with upcoming modification project – Goal is recapture of volume lost due to sedimentation (~ 35kaf) Challenges

• Aging Infrastructure

• Competition for Federal Funding

• Challenges with the Endangered Species Act Milk River Project Authorized in 1903 Montana Dam Safety Activities

Major Activities: • Nelson Dikes Modification – Completed in 2017 • Fresno Dam Modifications – Initiated in 2017

11 Nelson Dikes

12 Fresno Dam Lower Yellowstone Project • The pallid sturgeon was listed as endangered in 1990. • Corps of Engineers and Reclamation have been working on improving passage and reducing entrainment since early 2000’s. Lower Yellowstone Project

• Reclamation & Corps EA/FONSI in April 2015 (Bypass Channel)

• Legal challenge by Defenders of Wildlife and Natural Resource Defense Council – Preliminary Injunction Issued Stopping Construction

• EIS and Record of Decision: December 2, 2016 – Bypass Alternative – Construction Proceeded

• Preliminary Injunction Granted: July 5, 2017 – Corps is terminating the construction contract.

• Federal Agencies Appealed PI Ruling: September 2017 – Hearing Scheduled: March 5, 2018 - Portland Oregon – Ruling on PI Appeal: ~ 1 year

• Plaintiffs Filed Motion for Summary Judgement: December 2017 – Potential Hearing in Great Falls, MT: Late Summer/Early Fall 2018 – Ruling on the Merits of the Case: ~ 1 to 1.5 years. Lower Yellowstone Project

Current Status – Ongoing Studies

• Compliance with 2016 Biological Opinion

• Translocation – Very Successful in 2016 – 5 pallid sturgeon Translocation – 3 pallid sturgeon migrated 150 miles upstream (~100 miles up Powder River)

• Entrainment Monitoring – On-going since 2012 – Screens appear to be working, reduction in entrainment rates

• Passage Monitoring (Native Species) – Looking at passage success of: Shovelnose Sturgeon, Blue Sucker, Channel Catfish, Sauger

• Reclamation, Corps, MT FWP, USFWS, USGS Lower Yellowstone – Proposed Bypass Pallid Sturgeon St Mary Diversion Dam & Headworks Milk River Project International Boundary Waters Treaty

• Signed in 1909 • 1921 International Joint Commission (IJC) Order – Established Rules for sharing of St. Mary & Milk Rivers • Division of Flows – April 1 to October 31: – St. Mary River • Canada share is ¾ of Natural Flow up to 666 cfs • 50-50 share of flows in excess of 666 cfs – Milk River • US share is ¾ of Natural Flow up to 666 cfs • 50-50 share of flows in excess of 666 cfs St. Mary Diversion Dam & Headworks

• Bull Trout – Listed as threatened in 1999

– Diversion Dam restricts upstream and downstream passage

– Headworks entrain bull trout during the irrigation season. Questions & Discussion?
