Assessment of Natural Stream Sites for Hydroelectric Dams in the Pacific Northwest Region

Description: This pilot study presents a methodology for modeling project characteristics using a development model of a stream obstructing dam. The model is applied to all individual stream reaches in hydrologic region 17, which encompasses nearly all of Idaho, Oregon, and Washington. Project site characteristics produced by the modeling technique include: capacity potential, principal dam dimensions, number of required auxiliary dams, total extent of the constructed impoundment boundary, and the surface area of the resulting reservoir. Aggregated capacity potential values for the region are presented in capacity categories including total, that at existing dams, within federal and environmentally sensitive exclusion zones, and the balance which is consider available for greenfield development within the limits of the study. Distributions of site characteristics for small hydropower sites are presented and discussed. These sites are screened to identify candidate small hydropower sites and distributions of the site characteristics of this site population are presented and discussed. Recommendations are made for upgrading the methodology and extensions to make the results more accessible and available on a larger scale.

Hydroacoustic Evaluation of Juvenile Salmonid Passage and Distribution at Detroit Dam, 2011

Description: Pacific Northwest National Laboratory evaluated juvenile salmonid passage and distribution at Detroit Dam (DET) on the North Santiam River, Oregon for the U.S. Army Corps of Engineers (USACE) to provide data to support decisions on long-term measures to enhance downstream passage at DET and others dams in USACE’s Willamette Valley Project. This study was conducted in response to regulatory requirements necessitated by the listing of Upper Willamette River Spring Chinook salmon (Oncorhynchus tshawytscha) and Upper Willamette River steelhead (O. mykiss) as threatened under the Endangered Species Act. The goal of the study was to provide information of juvenile salmonid passage and distribution at DET from February 2011 through February 2012. The results of the hydroacoustic study provide new and, in some cases, first-ever data on passage estimates, run timing, distributions, and relationships between fish passage and environmental variables at the dam. This information will inform management decisions on the design and development of surface passage and collection devices to help restore Chinook salmon populations in the North Santiam River watershed above DET. During the entire study period, an estimated total of 182,526 smolt-size fish (±4,660 fish, 95% CI) passed through turbine penstock intakes. Run timing peaked in winter and early spring months. Passage rates were highest during late fall, winter and early spring months and low during summer. Horizontal distribution for hours when both turbine units were operated simultaneously indicated Unit 2 passed almost twice as much fish as Unit 1. Diel distribution for smolt-size fish during the study period was fairly uniform, indicating fish were passing the turbines at all times of the day. A total of 5,083 smolt-size fish (± 312 fish, 95% CI) were estimated passed via the spillway when it was open between June 23 and September 27, 2011. Daily passage was low at the spillway ...

Selected Flow Characteristics of Florida Streams and Canals

Description: Abstract: This report contains data and statistics on low-flow frequency for 254 stream-gagins stations on Florida streams and canals. The selected stations have 10 or more years of continuous record. A site description, a 10-year hydrograph, and a table of flow duration are presented for each station. A computed monthly 7-day, 10-year low flow is presented for stations when flow is not significantly altered by dams, increased or decreased significantly by diversion, or influence by tides.

Construction and Use of Farm Weirs

Description: "The purpose of this bulletin is to give practical directions for the construction and use of the smaller sizes of weirs, such as are suited to the measurement of water on irrigated farms.... The weirs described in this bulletin are the rectangular, Cipolletti, and 90 degree triangular-notch types, with free fall, sharp crests, and complete contractions." -- p. 1-2

State-of-the-Art for Assessing Earthquake Hazards in the United States: Report 19, The Evidence for Reservoir-Induced Macroearthquakes

Description: Partial abstract: "The published evidence of reservoir-induced macroearthquakes is critically reviewed. The evidence is partitioned into three types: (a) evidence of a post-impoundment increase in seismicity, (b) correlation evidence that is composed of a plot of a reservoir variable and a seismicity variable and, in most cases, an auxiliary variable, time, and (c) evidence based on the slope of the magnitude-frequency relationship (b value evidence)."

Financial analysis of experimental releases conducted at Glen Canyon Dam during water year 2011

Description: This report examines the financial implications of experimental flows conducted at the Glen Canyon Dam (GCD) in water year 2011. It is the third report in a series examining financial implications of experimental flows conducted since the Record of Decision (ROD) was adopted in February 1997 (Reclamation 1996). A report released in January 2011 examined water years 1997 to 2005 (Veselka et al. 2011), and a report released in August 2011 examined water years 2006 to 2010 (Poch et al. 2011). An experimental release may have either a positive or negative impact on the financial value of energy production. This study estimates the financial costs of experimental releases, identifies the main factors that contribute to these costs, and compares the interdependencies among these factors. An integrated set of tools was used to compute the financial impacts of the experimental releases by simulating the operation of the GCD under two scenarios, namely, (1) a baseline scenario that assumes both that operations comply with the ROD operating criteria and the experimental releases that actually took place during the study period, and (2) a 'without experiments' scenario that is identical to the baseline scenario of operations that comply with the GCD ROD, except it assumes that experimental releases did not occur. The Generation and Transmission Maximization (GTMax) model was the main simulation tool used to dispatch GCD and other hydropower plants that comprise the Salt Lake City Area Integrated Projects (SLCA/IP). Extensive data sets and historical information on SLCA/IP powerplant characteristics, hydrologic conditions, and Western Area Power Administration's (Western's) power purchase prices were used for the simulation. In addition to estimating the financial impact of experimental releases, the GTMax model was also used to gain insights into the interplay among ROD operating criteria, exceptions that were made to criteria to accommodate the experimental ...

Colville Confederated Tribes' Performance Project Wildlife Mitigation Acquisitions, Annual Report 2006.

Description: The Colville Confederated Tribes Wildlife Mitigation Project is protecting lands as partial mitigation for hydropower's share of the wildlife losses resulting from Chief Joseph and Grand Coulee Dams. The Mitigation Project protects and manages 54,606 acres for the biological requirements of managed wildlife species that are important to the Colville Tribes. With the inclusion of 2006 acquisitions, the Colville Tribes have acquired approximately 32,018 habitat units (HUs) towards a total 35,819 HUs lost from original inundation due to hydropower development. This annual report for 2006 briefly describes that four priority land acquisitions that were considered for enrollment into the Colville Tribes Mitigation Project during the 2006 contract period.
