Despite these efforts, discoveries of zebra and quagga mussels continue to be made in waterbodies across North America each year (Figure 1). The past year was no different with new infestations of zebra and quagga mussels confirmed in Lake Winnipeg, Manitoba and Lake Powell, Utah/Arizona, respectively. These two lakes are very large, freshwater bodies that are also incredibly popular recreation sites. Efforts are being made to manage these new infestations; however, the considerable size of these waterbodies combined with the high amount of boat traffic on these lakes makes it highly likely that invasive zebra/quagga mussels will be transported to additional waters unless a comprehensive, regional prevention strategy is realized. Figure 1: Distribution of zebra and quagga mussel sightings. Zebra mussel occurrences are highlighted in red and quagga mussel occurrences are highlighted in green (Source: USGS, Nonindigenous Aquatic Species Maps at: http://nas.er.usgs.gov/taxgroup/mollusks/zebramussel/ Accessed on: 11/12/2014). The Lake Whatcom Management Program began implementing its watercraft inspection program in 2012 to prevent the introduction of zebra and quagga mussels, and other aquatic invasive species, to Whatcom County waters. To date, the program has conducted nearly 13,000 inspections and has intercepted one vessel transporting quagga mussels, 203 vessels transporting vegetation, and another 190 vessels with 2 standing water which is a primary pathway for the transport of mussel larvae and other aquatic invasive species. The program has not only helped to prevent the spread of additional aquatic invasive species to local waters, it has also helped to increase community awareness regarding the threats that aquatic invasive species pose to Washington waters and how to prevent their spread. The Lake Whatcom Management Program launched the first season of its watercraft inspection program on July 14, 2012 at Bloedel Donovan. The main goals of the program in its first year included establishing usage patterns for the lake, conducting education and outreach with boaters and park users, and determining the feasibility of implementing a mandatory watercraft inspection program for Lake Whatcom in 2013. As of September 30, 2012, almost 1,800 boater surveys and visual boat inspections had been conducted at Bloedel Donovan. In 2013, the Lake Whatcom Management Program completed the second season of its watercraft inspection program, which required all motorized and/or trailered watercraft to be inspected for aquatic invasive species and to display a valid aquatic invasive species permit sticker prior to launching or operating on Lake Whatcom or Lake Samish. An Aquatic Invasive Species Check Station was opened at Bloedel Donovan on April 27, 2013 and was staffed between 5 a.m. and 9 p.m., 7 days a week. Aquatic invasive species inspectors were responsible for conducting education and outreach at the launch, conducting boater surveys, conducting visual and physical inspections of all watercraft, and selling aquatic invasive species permit stickers. As of October 30, 2013, aquatic invasive species inspectors had conducted over 3,000 inspections at Lake Whatcom and Lake Samish and sold 1,923 Annual Permits and 311 Three- Day Passes. The Lake Whatcom Management Program completed the third season of its watercraft inspection program in 2014, which required all watercraft to be inspected and permitted prior to launching or operating on Lake Whatcom or Lake Samish. Aquatic Invasive Species Check Stations were located at Bloedel Donovan, the Washington Department of Fish and Wildlife (WDFW) Launch at South Bay, and the WDFW Launch at Lake Samish. Additional inspections were conducted at private residences as well as at the Sudden Valley Marina and AM/PM Beach. As of September 30, 2014, aquatic invasive species inspectors conducted over 7,800 inspections at Lake Whatcom and Lake Samish and sold 2,327 Motorized Annual Permits, 2,438 Non-Motorized Annual Permits, and 414 Three-Day Passes. The annual total number of watercraft inspections conducted during the 2012, 2013, and 2014 boating seasons is illustrated in Figure 2. 2014 was the first season in which non-motorized watercraft, such as canoes and kayaks, were also required to be inspected and permitted prior to launching at Lake Whatcom or Lake Samish. The formation of partnerships between the Aquatic Invasive Species Program and local paddling and rowing clubs and organizations proved to be very valuable in fostering support for the program in 2014. As of September 30, aquatic invasive species inspectors had conducted over 3,500 non-motorized inspections at Lake Whatcom and Lake Samish. Also in 2014, the Lake Whatcom Management Program launched a new Whatcom Boat Inspections website and online Aquatic Invasive Species (AIS) Awareness Course. The website provides a central 3 location for program updates, fees, inspection locations, AIS prevention information, and a link to the new AIS Awareness Course. Successful completion of the online course in 2014 entitled participants to a discount on each annual permit being purchased. The AIS Awareness

  • BC Hydro Dam Safety Quarterly Report
    Confidential - Discussion/Information Board briefing – DAM SAFETY QUARTERLY REPORT Executive Summary The purpose of this report is to update the Capital Projects Committee of the Board of Directors on key dam risk management activities during the period from April 1, 2019 to June 30, 2019, and to provide reasonable assurance that the safety of dams operated by BC Hydro continues to be managed to the established guidelines and criteria of the Dam Safety Program. The Dam Safety Program has been executed in a manner that is consistent with its stated objectives throughout the reporting period. The overall Dam Safety risk profile is shown in Figure 1. There have been no changes in assessed risk this quarter. Risk Profile of BC Hydro’s Dam Dam Safety Contribution to Enterprise Risk Dam Safety is assigned a high “risk priority” within BC Hydro’s Enterprise Risk report, as depicted below. This high rating is arrived at by recognizing that: (1) there can be extremely severe consequences from the failure of a dam; (2) a dam failure can progress quickly without leaving adequate time to take effective actions to reverse the failure; and (3) our ability to mitigate this risk is considered to be “moderate” given that upgrades to existing dams are typically expensive, time and resource intensive and frequently technically challenging. The nature of dam safety risk is that it can only be realistically managed by minimizing to the extent practicable the probability of occurrence through a well-constructed and well-executed Dam Safety Program.

  • Revised Draft Experiences with Inter Basin Water
    REVISED DRAFT EXPERIENCES WITH INTER BASIN WATER TRANSFERS FOR IRRIGATION, DRAINAGE AND FLOOD MANAGEMENT ICID TASK FORCE ON INTER BASIN WATER TRANSFERS Edited by Jancy Vijayan and Bart Schultz August 2007 International Commission on Irrigation and Drainage (ICID) 48 Nyaya Marg, Chanakyapuri New Delhi 110 021 INDIA Tel: (91-11) 26116837; 26115679; 24679532; Fax: (91-11) 26115962 E-mail: [email protected] Website: http://www.icid.org 1 Foreword FOREWORD Inter Basin Water Transfers (IBWT) are in operation at a quite substantial scale, especially in several developed and emerging countries. In these countries and to a certain extent in some least developed countries there is a substantial interest to develop new IBWTs. IBWTs are being applied or developed not only for irrigated agriculture and hydropower, but also for municipal and industrial water supply, flood management, flow augmentation (increasing flow within a certain river reach or canal for a certain purpose), and in a few cases for navigation, mining, recreation, drainage, wildlife, pollution control, log transport, or estuary improvement. Debates on the pros and cons of such transfers are on going at National and International level. New ideas and concepts on the viabilities and constraints of IBWTs are being presented and deliberated in various fora. In light of this the Central Office of the International Commission on Irrigation and Drainage (ICID) has attempted a compilation covering the existing and proposed IBWT schemes all over the world, to the extent of data availability. The first version of the compilation was presented on the occasion of the 54th International Executive Council Meeting of ICID in Montpellier, France, 14 - 19 September 2003.

    State of California The Natural Resources Agency Department of Fish and Wildlife North Central Region Sugar Pine Reservoir, Placer County General Fish Survey October 4th, 2017 Mitch Lockhart Environmental Scientist December 28, 2017 Introduction Sugar Pine Reservoir is located in Placer County, approximately seven miles north of Foresthill, California (Figure 1) and sits amongst dense mixed-conifer forest at an elevation of 3,600 feet above mean sea level. The dam was built in 1979 to impound North Shirttail Creek and Forbes Creek, tributaries to the North Fork American River. When full, the reservoir stores approximately 6,900 acre-feet and has a surface area of 165 acres that services the community of Foresthill. The Tahoe National Forest manages the land and facilities around the reservoir, including a trail system, boat ramp, and two campgrounds to accommodate visitors. Figure 1: Google Earth overview image of Sugar Pine Reservoir, Placer County, California (retrieved Dec. 2017). The dam face is visible in the lower left corner of the photo. Shirttail Creek is visible in the upper right corner of the image and flows into the northern arm of the reservoir. Forbes Creek flows into the east arm of the reservoir and is visible in the right side of the image. Fish species known to occur in Sugar Pine Reservoir include: rainbow trout (RT; Oncorhynchus mykiss); brown trout (BN; Salmo trutta); spotted bass (SPB; Micropterus punctulatus); largemouth bass (LMB; Micropterus salmoides); smallmouth bass (SMB; Micropterus dolomieu); green sunfish (GSF; Lepomis cyanellus); bluegill (BG; Lepomis macrochirus); and bullhead catfish (BB; Ameiurus nebulosus).

  • Food Web E.2. Electronic Appendix
    E.2. Electronic Appendix - Food Web Elements of the Fraser River Basin Upper River (above rkm 210) Food webs: Microbenthic algae (periphyton), detritus from riparian vegetation and littoral insects (especially midges) are key components supporting fish production in the mainstem upper Fraser and larger tributaries. Collector-gatherers (invertebrates feeding on fine particulate organic material) are the most abundant functional feeding group, making up to 85% of the invertebrate species on the latter two rivers. Smaller tributaries are dominated by collector, shredder and grazer insect feeding modes (Reece and Richardson 2000). There is a general increasing trend in insect abundance from the headwaters of the main river to the lower river (Reynoldson et al. 2005). Juvenile stream-type Chinook rear along the shorelines of the upper river and tributaries and some overwinter under ice as the river margins usually freeze over here. Juvenile Chinook diets in the main stem and tributaries include larval plecopterans, empheropterans, chironomids and terrestrial insects (Homoptera, Coleoptera, Hymenoptera and Arachnida; Russell et al. 1983, Rogers et al. 1988, Levings and Lauzier 1991). Rainbow trout and northern pikeminnow consume mainly sculpins in the Nechako River as well as a variety of insects (Brown et al. 1992). Stressors: Water quality and habitat conditions have changed food webs in specific locations in the upper river. However, compared to other rivers in North America, water quality is good (Reynoldson et al. 2005), even with five pulp mills currently operating in the megareach. The food web of the Thompson River was stimulated in the past by low concentrations of bleached Kraft pulp mill effluent released into the river (Dube and Culp 1997); it is not known if this is still happening as treatment techniques for effluent have changed.
