Item of Note:
“One Government experiment farm is maintained near Mitchell, Nebraska, and another near Torrington, Wyoming. Both farms are of great value to the farmers of the valley. During the past year six cooperative retail stores and one wholesale store have been in operation. A cooperative cow testing association is doing great work in improving the quality of dairy cattle. There were twelve Farm Bureau local clubs and about the same number of Boys and Girls clubs in active existence throughout the year. Farmers of the valley are also active members of the Western Nebraska Potato Growers Association which is responsible for the valuable ‘Potato Grading Law’.”
Taken from “Project History Of The North Platte Project”; Nebraska-Wyoming; 1921; Volume 1; Page 11, Paragraph 25. Andrew Weiss, Project Manager

What Are “cfs” & “Acre-Foot”?•cfs Means “cubic feet per second” OR
“second-feet”
•One Cubic Foot Of Water Equals 7.48 Gallons Of Water
•One Cubic Foot Of Water Weighs 62.4 Pounds
•1 cfs = 449 Gallons Of Water Per Minute OR= 646,272 Gallons Of Water Per Day OR= 1.984 Acre-Feet Per Day
•1 Acre-Foot = 325,829 Gallons Of Water
•1 Acre-Foot = 43,560 Cubic Feet

•Pathfinder Dam, Dike & Reservoir – Trouble!!!•From The Middle Of & To The End Of June 1909,
Water In The Reservoir Rose Four Feet Per Day
•Run-off Was A Million Acre-Feet Above The Average
•Dynamite Was Placed In The Dam To Blow The Top 40 Feet Off, To Prevent The Unfinished Dike From Washing Out
•A 1949 Regrouting Project On Pathfinder Dam’s Downstream Face Revealed Five Sealed Drill Holes Loaded With Live Dynamite!
•After The 1909 Spring Flood, No-one Went Back To Remove The Dynamite
•The Dynamite Was Neutralized & Safely Removed

North Platte River Projects & Systems•Pathfinder Dam Tragedy
•Various Injuries Occurred During Construction Of Pathfinder Dam
•On February 9, 1912 Construction Work On The Concrete Ladder Located On The South Wall Of The Canyon Was Taking Place
•Three Anchor Cables Broke For The Main Cableway
•The Main Cable Swept 5 Men Off The Top Of The Canyon To Their Deaths
•The Coroner’s Jury / Inquest Determined The Accident Was Unavoidable & Was Not Caused By Carelessness Or Negligence Of Any One

North Platte River Basin Projects•Pathfinder Dam Spillway Modification
Project – Completed 2012 •Will Increase Pathfinder Reservoir Capacity By Approximately
54,000 Acre-Feet, To Recapture Storage Space Lost To Sediment
•A Weir (Ogee) Was Constructed To Raise The Spillway 2.39 Feet
•34,000 Acre-Feet Of The Modification Would Go To The Platte River Environmental Account
•20,000 Acre-Feet Of The Modification Would Go To Municipalities, Replacement Water To Meet Wyoming’s Obligations Under The Modified Decree, Mitigation Water For New Wyoming Depletions To Satisfy The Requirements Of The PRRIP & Additional Water For The PRRIP If Wyoming Does Not Need The Water
•The State Of Wyoming Will Pay For The Modification
•Part Of The Platte River Cooperative Agreement / Recovery Program
•Both Accounts Carry A “Change Of Use” To The 1904 Water Right, With A Limitation On The Ability To Call For The Water
