Flathead Indian Irrigation Project Flathead River Pumping Plant Topographic and Bathymetric Survey Request for Qualifications (Rfq) The Confederated Salish and Kootenai Tribes Department of Natural Resources Division of Engineering and Water Resources (DEWR) Irrigation & Infrastructure Program Ronan, Montana FLATHEAD INDIAN IRRIGATION PROJECT FLATHEAD RIVER PUMPING PLANT TOPOGRAPHIC AND BATHYMETRIC SURVEY REQUEST FOR QUALIFICATIONS (RFQ) Due Date: February 2, 2021 at 2:00 p.m. (local) Point of Contact: Dan Lozar, DEWR Manager Office Phone: (406) 676-2600 Email: [email protected] FLATHEAD INDIAN IRRIGATION PROJECT FLATHEAD RIVER PUMPING PLANT TOPOGRAPHIC AND BATHYMETRIC SURVEY REQUEST FOR QUALIFICATIONS (RFQ) CONFEDERATED SALISH AND KOOTENAI TRIBES NATURAL RESOURCES DEPARTMENT DIVISION OF ENGINEERING & WATER RESOURCES IRRIGATON INFRASTRUCTURE PROGRAM SECTION 01: PROJECT BACKGROUND The Confederated Salish and Kootenai Tribes Irrigation Infrastructure Program (CSKT) is soliciting RFQ’s from well-qualified engineering and/or surveying firms (Consultant) to collect survey-grade topography and bathymetry of the area surrounding the Flathead River Pumping Plant (FRPP). The FRPP is owned and operated by the Bureau of Indian Affairs - Flathead Indian Irrigation Project (FIIP) on the Flathead Reservation. The FRPP was designed and constructed during the late 1930’s and early 1940’s. It supplies supplementary irrigation water from the Flathead River to the northern Mission Valley. The FRPP is located on the river- left bank of the Flathead River approximately 2.5-miles southwest of Polson, MT. Access to the facility is via Kerr Dam Road (SR 354) and a two-track gravel road. CSKT is currently in the early stages of a Scoping Study which intends to evaluate the rehabilitation and/or replacement potentials for the FRPP. A key data component for this Scoping Study is a detailed understanding of the topography surrounding the FRPP as well as a detailed bathymetry of the Flathead River bed surrounding the pump intakes. Another key component of the Scoping Study is to coordinate the horizontal and vertical datums at SKQ Dam and the USGS Flathead Lake gauge with the FRPP in order to better understand the hydraulic connectivity between Flathead Lake, the FRPP pump intakes, and the SKQ Dam forebay water surface elevations. Survey work is anticipated to include both bathymetric (below-water surface) sonar data collection and above-water surface topographic data collection using Light Detection and Ranging (LiDAR) in the areas surrounding the FRPP. Additionally, the horizontal and vertical control benchmarks at the SKQ Dam and the USGS Flathead Lake gauge will be resolved to new control benchmarks at the FRPP. Project deliverables will include preparation of a seamless survey dataset, a seamless digital terrain model, and a one-foot contour topography and bathymetry map at the FRPP. Additional deliverables include installation and mapping of 3 (three) new survey control benchmarks at or near the FRPP, survey mapping of three (3) existing SKQ Dam control points, and survey mapping of three (3) USGS benchmarks near Salish Point in Polson, MT. The Consultant will complete work under the responsible charge of a professional land surveyor licensed to conduct land surveys in the State of Montana. 1 The project will be administered by the CSKT. Specific aspects of the project will be coordinated with Energy Keepers, Inc. (EKI), the operational and maintenance managers of SKQ Dam, and the BIA, the operational and managers of the Flathead Indian Irrigation Project. SECTION 02: SCOPE OF SERVICES 2.0 Overview Consultants who respond to this RFQ will be required to submit their technical approach to collect, process, and submit deliverables. At this time, the CSKT anticipate the data collection will include a combination of boat-based, multi-beam sonar synchronized with RTK GPS, terrestrial RTK GPS, and airborne LiDAR. Alternate approaches meeting project objectives will be considered. Access to the FRPP includes SR-354, a canal road, and a two track maintenance road. Access to the USGS Flathead Lake Gauge is via City of Polson streets. Access to SKQ Dam will be by paved roads but due to security concerns will be by appointment only. Access to proposed CP3, which is located on the river right bank opposite the FRPP, is likely by boat. No CSKT led site visits will be conducted at the three discrete project locations prior to the submission of RFQ’s by the Consultant. 2.1 Workflow 1. The selected Consultant will meet with the CSKT to finalize the Contract Agreement which will include all required documentation from this RFQ and an agreed upon fee. 2. The selected Consultant will complete a one day field trip with the CSKT and potentially others to address any field-related questions. 3. The selected Consultant will prepare a field implementation plan for review and approval by the CSKT. 4. On approval of the field plan, the selected Consultant will complete survey work, data integration, data delivery, project reporting, and project completion. 2.3 Project Deliverables 2.3.1 Survey Control, Projections, Datum, Units, and Accuracy 1. The Consultant will set three (3) permanent survey control monuments at or near the FRPP. Survey control monument materials and installation to meet Department of Interior – Bureau of Land Management and Bureau of Indian Affairs standards. Generally, the control points will be located as follows: CP1 will be located within 50-ft of the FRPP building at a location visible from CP2 and CP3; CP2 will be located near the top or discharge end of the penstocks and must be visible from CP1 and CP3; CP3 will be located on the river-right bank of the Flathead River approximately 10-ft above the maximum water surface elevation; 2. The Consultant will horizontally and vertically map three (3) USGS reference markers near Salish Point in Polson, MT. The reference marks are as follows: RM14 is an aluminum cap located in the west side of dock nearest the parking area; RM15 is brass cap located in the northeast corner of the gage house concrete floor slab; 2 RM16 is an “X” mark cut into the top of a steel H-pile located approximately 20-ft west of RM14. 3. The Consultant will horizontally and vertically map three (3) SKQ Dam control points near the dam crest. Access to these control points will be provided by EKI personnel only. The control points are as follows: WASH LAKE VISTA 4. The Consultant will provide a set of corrected control point files projected to Montana State Plane (FIPS 2500) and vertical and horizontal datums NAVD88 Geoid03 and NAD83 for CP1, CP2, CP3, RM14, RM15, RM16, WASH, LAKE, and VISTA. 5. The Consultant will provide all topographic and bathymetric survey data with less than or equal to one (1) foot absolute accuracy for the areas noted in Figure 1.0; 2.3.2 Specific Deliverables The selected Consultant will provide, at a minimum, the following project deliverables. 1. The Consultant will prepare a field implementation plan, including a detailed field execution schedule, to complete survey activities. The field plan will be reviewed and approved by the CSKT prior to initiating field work. The Consultant will work with CSKT and EKI staff to obtain access to the SKQ Dam control points; The Consultant will work with CSKT and BIA-FIIP staff to gain access to the FRPP. It is very likely the FRPP will be in operating during the survey acquisition timeframe. FRPP operations may not be disturbed or adjusted to facilitate survey efforts. The field implementation plan will include a protocol to adhere to aquatic invasive species prevention procedures for field activities; adherence to this protocol should be factored into work products noted herein. 2. Topographic and bathymetric survey data collected by various means will be processed into a single seamless basemap for submission to the CSKT. Data will be submitted in digital format including but not limited to: .las and/or .txt formats, .dfx/.dwg formats, and ArcGIS 10.x raster-compatible format; 3. Topographic and bathymetric survey data will be processed into a seamless digital terrain model compatible for engineering related use and manipulation in ArcGIS 10.x, AutoCAD, and/or MicroStation programs; 4. The Consultant will provide a high-resolution georeferenced aerial image within the noted topographic and bathymetric survey bounds.

  • What's the Deal with Flathead Lake and Lake Trout
    PO Box 7186 Missoula, MT 59807 (406) 543-0054 PO Box 638 Kalispell, MT 59903 (406) 260-1198 What anglers should know about Flathead Lake, lake trout, and native trout Are lake trout the main reason native bull trout and cutthroat trout are disappearing from Flathead Lake and the Flathead River and its Middle and North forks? Yes. Biologists agree that the primary culprit in the precipitous decline in bull trout and cutthroat trout in the Flathead system the last 20 years is predation from an expanding population of non-native lake trout in Flathead Lake. How can lake trout in Flathead Lake be harming bull and cutthroat trout in the river? Biologists have long known that most of the bull trout and a portion of the cutthroat trout found in the main Flathead River, as well as in its North and Middle Forks, are migratory and they spend part of their lives in Flathead Lake. They move to the river to spawn and spend the first few years of their lives rearing in tributaries, before descending to the lake where they fall prey to or are otherwise outcompeted by voracious lake trout. So, what is the status of bull trout and cutthroat trout in the Flathead system? Based on annual counts of spawning redds and historical angling data, it is clear that the bull trout population is a fraction of what it was historically. This is a primary reason the U.S. Fish and Wildlife Service listed this fish species as “threatened.” Absolute numbers on cutthroats are hard to come by, but based on limited field data and anecdotal information it appears their numbers are also drastically reduced.

  • White Paper on COLUMBIA RIVER POST-2024 FLOOD RISK MANAGEMENT PROCEDURE
    White Paper on COLUMBIA RIVER POST-2024 FLOOD RISK MANAGEMENT PROCEDURE U.S. Army Corps of Engineers Northwestern Division September 2011 This page intentionally left blank PREFACE The Columbia River, the fourth largest river on the continent as measured by average annual flow, provides more hydropower than any other river in North America. While its headwaters originate in British Columbia, only about 15 percent of the 259,500 square miles of the river’s basin is located in Canada. Yet the Canadian water accounts for about 38 percent of the average annual flow volume, and up to 50 percent of the peak flood waters, that flow on the lower Columbia River between Oregon and Washington. In the 1940s, officials from the United States and Canada began a long process to seek a collaborative solution to reduce the risks of flooding caused by the Columbia River and to meet the postwar demand for energy. That effort resulted in the implementation of the Columbia River Treaty in 1964. This agreement between Canada and the United States called for the cooperative development of water resource regulation in the upper Columbia River Basin. The Columbia River Treaty has provided significant flood control (also termed flood risk management) and hydropower generation benefiting both countries. The Treaty, and subsequent Protocol, include provisions that both expire on September 16, 2024, 60 years after the Treaty’s ratification, and continue throughout the life of the associated facilities whether the Treaty continues or is terminated by either country. This white paper focuses on the flood risk management changes that will occur on that milestone date and satisfies the following purposes: 1.

  • Safeguarding the West from Invasive Species
    Safeguarding the West from Invasive Species Actions to Strengthen Federal, State, and Tribal Coordination to Address Invasive Mussels PROGRESS REPORT FEBRUARY 2019 Progress Report n June 2017, the U.S. Department of the Interior (DOI) announced a set of Iactions that it is undertaking to protect western waters from invasive quagga and zebra mussels (Dreissana rostriformis bugensis and D. polymorhpa). Invasive mussels pose significant threats to water-based recreation, hydropower, water delivery, fisheries, and aquatic ecosystems. DOI led this call-to-action in the spring of 2017 in collaboration with the Western Governors’ Association (WGA), and federal, state, and tribal representatives. This intergovernmental process resulted in the report, Safeguarding the West from Invasive Species: Actions to Strengthen Federal, State, and Tribal Coordination to Address Invasive Mussels [hereafter, Safeguarding the West], which describes DOI commitments to prevent, contain, and control invasive mussels in the West. The Safeguarding the West initiative builds on decades of federal-state collaboration and advances priorities identified in interagency plans, including the Quagga-Zebra Mussel Action Plan (QZAP) for Western U.S. Waters developed by the Western Regional Panel on Aquatic Nuisance Species. Through Safeguarding the West, DOI leveraged investments to address invasive mussels, strengthened relationships with WGA, states, tribes, and partners, and increased DOI engagement at national, regional, and field levels on policy and program initiatives. This is DOI’s second Safeguarding the West progress report and provides a status update on activities that occurred in 2018. DOI released its first progress report in February 2018. While much has been accomplished, more work needs to be done.

  • Westslope Cutthroat and Bull Trout Populations; Key Habitat
    Item 28: Bull Trout and Westslope Cutthroat Trout Populations Evaluation Objectives: Monitor changes in bull trout and westslope cutthroat populations in key habitats on the forest. Methods: Fish population monitoring is generally conducted by Montana Fish, Wildlife, and Parks (MT FWP). Population estimates are determined using standard methods such as depletion, mark-recapture, and redd counts. Since 1980, MT FWP has been monitoring bull trout populations in the Flathead Basin using redd counts. Adult bull trout reside in Flathead Lake, Swan Lake, and Hungry Horse Reservoir. In the fall, these fish spawn in tributary streams and their redd numbers are a useful way to monitor their populations. Westslope cutthroat trout populations are generally monitored through electro-fishing surveys in several index streams across the forest. Evaluation: Figure 1 summarizes bull trout redd count data across the forest by sub-basin. This data set includes index streams only (where redds are counted every year). It is clear that the Swan sub-basin contains the highest number of redds on the forest, and appears to have peaked in 1998, probably due to restrictive fishing regulations in Swan Lake and its tributaries in 1993. Lower numbers are found in the North and Middle forks of the Flathead River system. Index counts have been conducted on four North Fork and four Middle Fork tributaries annually since 1980. In the mid to late 1980s, the establishment of Mysis shrimp changed the species composition and food web dynamics in Flathead Lake, and allowed lake trout numbers to increase rapidly. As a result, bull trout numbers began declining in the North and Middle forks of the Flathead due to competition/predation with Lake trout (Figure 1).
