December 18, 2020 Fish Consumption Guidance Updated for Portions Of
Media contact: Trevor Selch, FWP Fisheries Pollution Biologist, 406-444-5686 FOR IMMEDIATE RELEASE: December 18, 2020 Fish consumption guidance updated for portions of Clark Fork, Bitterroot and Blackfoot Rivers in western Montana MISSOULA – The State of Montana Fish Guidance Board, which includes Montana Fish, Wildlife & Parks (FWP) and the Departments of Environmental Quality (DEQ), and Public Health and Human Services (DPHHS), has updated the fish consumption guidance for all species of fish on a 148-mile stretch of the Clark Fork River and tributaries in western Montana in response to new research results. Guidance now recommends avoiding consumption of all species of fish from the Clark Fork River’s confluence with the Bitterroot River, just west of Missoula, to the confluence with the Flathead River, near Paradise. Slightly revised guidance is also in place for rainbow trout and northern pike on an upstream section of the Clark Fork and for the Blackfoot and Bitterroot Rivers. New data was collected to assess chemical contaminants including dioxins, furans, and PCBs in fish tissue in a study area on the Clark Fork that extended from approximately 30 miles upstream of Missoula to 100 miles downstream. Testing in the area is underway as part of water quality monitoring around the former Smurfit-Stone Container mill site. Upon review of the study results, new guidance was issued based on high levels of contaminants in the fish tissue. The source of all the contaminants found in the fish has not been attributed. The study only looked at contaminant concentrations found in the muscle tissues of northern pike and rainbow trout, but the same “Avoid” guidance extends to all species present in the Clark Fork River near Missoula (such as brown trout, whitefish, small- and large-mouth bass, northern pikeminnow, and sucker species) because similar food habits, habitat use, and life- span suggest they could also contain chemical concentrations at potentially dangerous levels. -

THE LIVING MURRAY Information Paper No. 10 IPTLM0010 Health of the River Murray Menindee Lakes, the Lower Darling River and Darling Anabranch) Contents Environmental assets within the river zone Current condition of environmental assets Reasons why some environmental assets have declined in value What can be done to restore environmental values? Existing environmental flows initiatives The system-wide perspective References Introductory Note Please note: The contents of this publication do not purport to represent the position of the Murray-Darling Basin Commission. The intention of this paper is to inform discussion for the improvement of the management of the Basin’s natural resources. 2 Environmental assets within the river zone The lower Darling River system is located at the downstream end of the River Murray system in NSW and is marked by Wentworth to the south and Menindee to the north. It encompasses the Menindee Lakes system, the Darling River below Menindee and the Great Anabranch of the Darling River (referred to hereafter as the Darling Anabranch) and associated lakes. These are iconic riverine and lake systems within the Murray-Darling Basin. In addition, a vital tributary and operating system feeds the lower River Murray. The climate of the area is semi-arid with an annual average rainfall of 200 mm at Menindee (Auld and Denham 2001) and a high potential annual evaporation of 2,335 mm (Westbrooke et al. 2001). It is hot in summer (5–46oC) and mild to cold in winter (-5–26oC). In particular, the lower Darling River system is characterised by clusters of large floodplain lakes, 103 to 15,900 ha in size, located at Menindee and along the Darling Anabranch. -

Wandering rivers are important because they Toronto, M5S 3G3, Canada. provide habitat complexity for aquatic organisms, including salmonids. An anabranch cycle E-mail: [email protected] model was developed from previous literature and field observations to illustrate how anabranches within the wandering pattern change from single to multiple channels and vice versa over a number of decades. The model was used to investigate the temporal dynamics of a wandering river through historical case studies and channel characteristics from field data. The wandering Renous River, New Brunswick, was mapped from aerial photographs (1945, 1965, 1983 and 1999) to determine river pattern statistics and for historical analysis of case studies. Five case studies consisting of a stable single channel, newly formed anabranches, anabranches gaining stability following creation, stable anabranches, and an abandoning anabranch were investigated in detail. -
The Form of a Channel
23 GEOMORPHOLOGY 201 READER The bankfull discharge is that flow at which the channel is completely filled. Wide variations are seen in the frequency with which the bankfull discharge occurs, although it generally has a return period of one to two years for many stable alluvial rivers. The geomorphological work carried out by a given flow depends not only on its size but also on its frequency of occurrence over a given period of time. The flow in river channels exerts hydraulic forces on the boundary (bed and banks). An important balance exists between the erosive force of the flow (driving force) and the resistance of the boundary to erosion (resisting force). This determines the ability of a river to adjust and modify the morphology of its channel. One of the main factors influencing the erosive power of a given flow is its discharge: the volume of flow passing through a given cross-section in a given time. Discharge varies both spatially and temporally in natural river channels, changing in a downstream direction and fluctuating over time in response to inputs of precipitation. Characteristics of the flow regime of a river include seasonal variations in discharge, the size and frequency of floods and frequency and duration of droughts. The characteristics of the flow regime are determined not only by the climate but also by the physical and land use characteristics of the drainage basin. Valley setting Channel processes are driven by flow and sediment supply, although the range of channel adjustments that are possible are often restricted by the valley setting. -
