CCM 2013 09-26 SLOUGH ■ JEFFERSON SLOUGH LANDOWNER MEETING September 26, 2013 Present: Commissioner Wortman, Tim Mulligan, Larry Weidinger, Wayne Turner, Joe Davis, Kay Ann Davis,Tom Salvagni, Tara Mastei,Mike Welch, Kate ?, Jodi Kountz, Greg Corr,Bob Casagrande,Terrie Casagrande,Gerry Keogh, Ron Spoon, Dean Briggs, Ted Dodge, Mike Sanctuary,Jim Lovell Commissioner Wortman welcomed those in attendance and gave a brief background of the project. He said that they are going to have to study and determine if any work done could affect those downstream. Confluence Contracting is going to be seeking input from landowners and hope to gain insight from their historical knowledge. He noted that this is a county project and the county will have final say on what work will be done. The county has made a commitment that nothing will be done without the approval of the landowners. The Jefferson Slough has been found to be the nursery for Eurasian milfoil in the Jefferson River, so this project could • have a huge impact. Jim Lovell, Confluence Consulting, gave an overview of the firm and some of the project that they have been involved with in the past. They are currently getting background, baseline information on the Slough. They are conducting flow studies so they can have an idea of the flow expected at certain times of the year. Their second focus will be looking at how the Slough functions. They will be surveying and doing water measurements over a 12-month period. At the end of that time,they will write up a report with their recommended projects. They want to meet with all of the landowners to gain their insight of how the Slough flows at various times throughout the year. Tim Mulligan stated that as a landowner he has been watching what has been happening with the Slough, and it is heartbreaking. The increase of sand, sediment,weeds and cat tails has affected water use, which is important for land values, recreation and business. Commissioner Wortman said that with funding from the legislature we will have money for construction on the Pipestone and conceptual design and flow study on the Slough. There is also a good opportunity for gaining more funds at the next legislature. Jim stated that they are really looking for community involvement. Commissioner Wortman said that his goal is to have a landowner meeting every other month so that everyone can stay up-to-date on what is happening with the project. Tim Mulligan noted that the Technical Advisory Committee meetings are open to the public as well. Jim said that part of their work plan is to understand the flow at different times of year in various places - Pipestone Creek,Whitetail Creek, the top,middle and bottom of the Slough. Next 9-26-2013 Jefferson Slough Landowner Meeting -1- ■ summer they will be conducting flow studies between those points and measuring the water coming in at different places. Norm Tebay asked when they will be talking to the landowners. Jim said that it will be soon; they want to get the flow measuring stations in the water in October and most will be on private land. They also need to place temperature monitors as water temperatures affect milfoil. Ron Spoon, FWP, stated that the Bureau of Mines is doing some groundwater studies. Jim stated that he just found out about that earlier in the day. He is going to contact them to see if they can share their information. Confluence will be collecting data from now until August and will then write their report. They will also need to do an assessment of the condition of the channel. This will need to be done in early Spring before the run off and there are leaves on the trees. Tim Mulligan asked how they do the geomorphology. Jim said that they will walk or float from one end of the Slough to the other and test sediment and its depth,vegetation, the depth of the channel, size of bed material, and locating places where it seems the sediment is being transported well.

This is the uppermost infestation of EWM in the Missouri River Watershed. • Crews hand-pulled 4458 pounds of EWM and other aquatic vegetation in upper 1.68 miles of infestation. Herbicide option are limited in flowing watersystem. • In addition to the hand-pulling, characterization data (sediment depth, vegetation, channel width,water flow)was collected to assist with determining a long-term solution to management. • This work was accomplished by a partnership between County Weed Districts, Conservation District volunteers, DNRC, FWP, MDA, Montana Conservation Corp and Golden Sunlight Mine crews. • Continual on-going watershed work is being conducted as part of the Big Pipestone project to look at feasible options for EWM and other aquatic vegetation control and sediment removal in the slough. • This work was made possible by the State Legislature through the HB 7 funds. On behalf of the Jefferson County Weed District we ask for your continued support of Aquatic Invasive Species funding to DNRC so that the cooperative effort between the agencies can continue to combat invasive in our Montana waters. • ��..

In the past loo years, the natural drainage patterns of Big Pipestone Creek and the Jefferson Slough have been altered,riparian vegetation removed,and structures created that impede flow,changing the health and flow regime of these tributaries to the Jefferson River. These problems affect not only local water users and irrigators, but also the Town of Whitehall. And because the Jefferson Slough hosts the uppermost infestation of Eurasian watermilfoil, these impairments affect Montana's entire Missouri River system. The, gacti, of thidr project is to restore Big Pipestone Creek and the Jefferson Slough to healthy waterways that sustain irrigated agriculture,improve riparian areas and the fishery,and minimize vulnerability from natural disasters. Werk befit* th summer t»- meet the. fo owCs ob ectivet' • Eliminate the infestation of Eurasian watermilfoil in the Jefferson Slough • Reduce sediment load,temperatures and nutrients • Improve riparian habitat • Reduce bank erosion and preserve arable land • improve access to permitted irrigation water • Reduce flood hazard to Whitehall Through the Department of Natural Resources and Conservation, the 2013 Montana Legislature committed $1.78 million for the next two years to address these critical restoration projects. In addition,local landowners are eligible for funding from the Natural Resource Conservation Service and the Montana Department of Environmental Quality to reduce bank loss and reclaim riparian areas. Je 'erso-tv Covt.i y and' the,Jef f ersoty Rover Watershed, Council, have partnered with landowners, natural resource specialists and funding agencies to restore this important watershed in the Missouri River headwaters. Two technical advisory committees guide this effort.

Eurasian watermilfoil thrives in slow moving silted waterways such as the Jefferson Slough. The growth of AIS in Montana has increased substantially, _ escalating the speed and volume of species r movement to unprecedented levels. That's why this restoration project includes removal of a significant source of Eurasian watermilfoil to Montana's Missouri River system. •- '•, :. � Vis•,, �:� Eurasian Watermilfoil in Jefferson Slough Lower Big Pipestone Creek • Stream/ Bank, Erosion/ • The Montana Department of Environmental Quality has declared Big Pipestone Creek as the second-worst stream in the State for sediment load. Severe bank erosion on the lower reaches of the creek reduces arable land, impair irrigation infrastructure, and contribute high volumes of silt to the Jefferson Slough. This restoration project will return critical portions of the creek to natural conditions. The, Town. of Whitehall/ experiences floods when high water backs up from Jefferson Slough. This restoration project will reduce the risk of flooding in Whitehall. - Future, protects- in need of funding include infrastructure reconstruction, creation of sediment traps such as beaver dams, settling ponds, and wetlands, and additional riparian protection and stream channel restoration.
