  • Gills Coulee Creek, 2006 [PDF]
    Wisconsin Department of Natural Resources Bureau of Watershed Management Sediment TMDL for Gills Coulee Creek INTRODUCTION Gills Coulee Creek is a tributary stream to the La Crosse River, located in La Crosse County in west central Wisconsin. (Figure A-1) The Wisconsin Department of Natural Resources (WDNR) placed the entire length of Gills Coulee Creek on the state’s 303(d) impaired waters list as low priority due to degraded habitat caused by excessive sedimentation. The Clean Water Act and US EPA regulations require that each state develop Total Maximum Daily Loads (TMDLs) for waters on the Section 303(d) list. The purpose of this TMDL is to identify load allocations and management actions that will help restore the biological integrity of the stream. Waterbody TMDL Impaired Existing Codified Pollutant Impairment Priority WBIC Name ID Stream Miles Use Use Gills Coulee 0-1 Cold II Degraded 1652300 168 WWFF Sediment High Creek 1-5 Cold III Habitat Table 1. Gills Coulee use designations, pollutants, and impairments PROBLEM STATEMENT Due to excessive sedimentation, Gills Coulee Creek is currently not meeting applicable narrative water quality criterion as defined in NR 102.04 (1); Wisconsin Administrative Code: “To preserve and enhance the quality of waters, standards are established to govern water management decisions. Practices attributable to municipal, industrial, commercial, domestic, agricultural, land development, or other activities shall be controlled so that all waters including mixing zone and effluent channels meet the following conditions at all times and under all flow conditions: (a) Substances that will cause objectionable deposits on the shore or in the bed of a body of water, shall not be present in such amounts as to interfere with public rights in waters of the state.

  • Northrup Canyon
    Northrup Canyon Why? Fine basalt, eagles in season Season: March to November; eagles, December through February Ease: Moderate. It’s about 1 ¾ miles to an old homestead, 3 ½ miles to Northrup Lake. Northrup Canyon is just across the road from Steamboat Rock, and the two together make for a great early or late season weekend. Northrup, however, is much less visited, so offers the solitude that Steamboat cannot. In season, it’s also a good spot for eagle viewing, for the head of the canyon is prime winter habitat for those birds. The trail starts as an old road, staying that way for almost 2 miles as it follows the creek up to an old homestead site. At that point the trail becomes more trail-like as it heads to the left around the old chicken house and continues the last 1 ½ miles to Northrup Lake. At its start, the trail passes what I’d term modern middens – piles of rusted out cans and other metal objects left from the time when Grand Coulee Dam was built. Shortly thereafter is one of my two favorite spots in the hike – a mile or more spent walking alongside basalt cliffs decorated, in places, with orange and yellow lichen. If you’re like me, about the time you quit gawking at them you realize that some of the columns in the basalt don’t look very upright and that, even worse, some have already fallen down and, even more worse, some have not quite finished falling and are just above the part of the trail you’re about to walk.

  • Fishway Ladder
    FREQUENTLY ASKED QUESTIONS A. Fishway B. Riverwalk C. DNR Compliance with NR 333 D. Dam Removal E. Property Issues F. Fish and Aquatic Life G. Wildlife H. Recreational Use A. Fishway 1. What is the estimated cost to build a fishway at Bridge Street dam? The engineering consultant, Bonestroo, has estimated the cost at $1.3 million per the NOAA grant. 2. If the fishway is constructed next year, will it have to be rebuilt when the dam needs to be removed and replaced? Essentially no. Most of the fishway is a separate upstream structure and will not be impacted by demolition and construction of a new dam. The fishway entrance area may need to be modified if a new dam is installed or if the dam abutments are altered. 3. Why is the fishway being constructed on the west bank of the river? The west bank allows land owned by the Village of Grafton to be used for a portion of the channel alignment. Furthermore, the heaviest construction will likely be in the area currently owned by the Village (penetration of the west dam abutment). Other advantages include the appeal to tourists able to view fish entering and ascending the fishway from the riverwalk, and the known presence of shallow bedrock helping assure good foundation characteristics. Furthermore, the historic mill race crosses the area, and a portion of the mill race alignment may assist with fishway construction. 4. How long will it take to complete the construction of the fishway? The fishway will be completed by late fall of 2010.

  • Chief Joseph Hatchery Program
    Chief Joseph Hatchery Program Draft Environmental Impact Statement DOE/EIS-0384 May 2007 Chief Joseph Hatchery Program Responsible Agency: U.S. Department of Energy, Bonneville Power Administration (BPA) Title of Proposed Project: Chief Joseph Hatchery Program Cooperating Tribe: Confederated Tribes of the Colville Reservation State Involved: Washington Abstract: The Draft Environmental Impact Statement (DEIS) describes a Chinook salmon hatchery production program sponsored by the Confederated Tribes of the Colville Reservation (Colville Tribes). BPA proposes to fund the construction, operation and maintenance of the program to help mitigate for anadromous fish affected by the Federal Columbia River Power System dams on the Columbia River. The Colville Tribes want to produce adequate salmon to sustain tribal ceremonial and subsistence fisheries and enhance the potential for a recreational fishery for the general public. The DEIS discloses the environmental effects expected from facility construction and program operations and a No Action alternative. The Proposed Action is to build a hatchery near the base of Chief Joseph Dam on the Columbia River for incubation, rearing and release of summer/fall and spring Chinook. Along the Okanogan River, three existing irrigation ponds, one existing salmon acclimation pond, and two new acclimation ponds (to be built) would be used for final rearing, imprinting and volitional release of chinook smolts. The Chief Joseph Dam Hatchery Program Master Plan (Master Plan, Northwest Power and Conservation Council, May 2004) provides voluminous information on program features. The US Army Corps of Engineers, Washington Department of Fish and Wildlife, Washington State Parks and Recreation Commission, Oroville-Tonasket Irrigation District, and others have cooperated on project design and siting.

  • Effects of Dams on Native Americans in the Columbia River Basin Elliott
    Dammed Societies: Effects of Dams on Native Americans in the Columbia River Basin Elliott McGill Senior Capstone Project Faculty Advisors: Dr. Jamie Dolan, Dr. Jeremy Johnson, and Dr. David McCanna McGill 1 Abstract Since dam construction began in the New Deal Era, it has represented a dominance of humankind over nature. These massive structures have harnessed, collected, and distributed electricity from the rivers they hold back and allow humans to reap the benefits of that cycle. One of the areas where dams are particularly apparent is in the Columbia River Basin in the Pacific Northwest region of the United States. While the dams in this region certainly have allowed the area to develop and build by using the electricity collected by these dams, they have also had several negative effects on the tribal people in the region who once fished the mighty Columbia during its populous salmon runs and relied on the salmon for nutritional, economic, and cultural reasons. This project seeks to examine the costs of human advancement when it comes to dams, and will do so by studying three dams located in the Columbia River Basin: The Bonneville Dam, The Dalles Dam, and The Grand Coulee Dam. These dams will be studied using Black’s Theory of Law as a framework to examine the manner in which law was applied to each case. The research finds that although the dams certainly provide a useful resource to the people of the region, it has had negative effects on the Native American people who depended on the river. McGill 2 Introduction When President Franklin D.
