The smallmouth bass is a species of freshwater fish in the sunfish family (Centrarchidae) of the order Perciformes. It is the type species of its genus Micropterus, and is a popular game fish sought by anglers throughout the temperate zones of North America, and has been spread by stocking—as well as illegal introductions—to many cool-water tributaries and lakes in Canada and more so introduced in the United States. The maximum recorded size is approximately 27 inches (69 cm) and 12 pounds (5.4 kg).
Angling is a fishing technique that uses a fish hook attached to a fishing line to tether individual fish in the mouth. The fishing line is usually manipulated via a fishing rod, although rodless techniques such as handlining also exist. Modern angling rods are usually fitted with a fishing reel that functions as a cranking device for storing, retrieving and releasing out the line, although Tenkara fishing and traditional cane pole fishing are two rod-angling methods that do not use any reel. The fish hook itself can be additionally weighted with a denser tackle called a sinker, and is typically dressed with an appetizing bait to attract and entice the fish into swallowing the hook, but sometimes an inedible fake/imitation bait with multiple attached hooks is used instead of a single hook with edible bait. Some type of bite indicator, such as a float, a bell or a quiver tip, is often used to relay underwater status of the hook to the surface and alert the angler of a fish's presence.
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water.
Tainter Lake is a small reservoir in north central Dunn County, Wisconsin, on the Red Cedar River at its confluence with the Hay River. The lake was created by a hydroelectric dam (about 3 miles downstream on the Red Cedar at Cedar Falls. The lake, a popular resort and fishing spot, has a surface area of approximately 2 square miles.
New Bullards Bar Reservoir is a large reservoir in northeastern Yuba County, California, United States, at an elevation of 2,000 feet (610 m) in the Tahoe National Forest and about 30 miles (50 km) northeast of Yuba City. The 969,600 acre-foot (1.1960×109 m3) reservoir is formed by New Bullards Bar Dam on the North Yuba River, a tributary of the Yuba River. It also receives a portion of the Middle Fork's flow that is diverted to the reservoir via tunnels.
High Rock Lake is a reservoir located on the Yadkin River in central North Carolina in the counties of Davidson and Rowan. Built in 1926-27 by the Tallassee Power Company, a wholly owned subsidiary of the Aluminum Company of America (Alcoa), the lake is the northernmost of a series of four hydroelectric projects designed at the time to support the company’s Badin Works, a large aluminum smelting operation located 16 miles downstream in the community of Badin. After the permanent closing of the Badin Works in 2007, Alcoa continued to operate its Yadkin hydroelectric facilities until selling them to Cube Hydro Carolinas in 2016.
The Eklutna River is approximately 11.8 miles (19.0 km) long and is located in the Southcentral region of the U.S. state of Alaska. A portion of the river flows through a canyon up to 400 feet (120 m) deep, emptying into the Knik Arm of Cook Inlet approximately 17 miles (27 km) northeast of Anchorage. This degraded anadromous stream historically originated from Eklutna Lake, which itself is fed by Eklutna Glacier. Eklutna River is now fed primarily by groundwater before being joined by Thunderbird Creek. Thunderbird Creek, which enters the south bank about 1 km (0.62 mi) upstream from where the river exits the canyon and forms an alluvial fan. Due to water impoundments on the Eklutna River for power generation, Thunderbird Creek is currently the main source of water in the lower portion of the Eklutna River. The river is located entirely within the limits of the Municipality of Anchorage.
The Saugatuck Reservoir is a reservoir in Fairfield County, Connecticut, United States, that straddles the border between the towns of Redding, Weston, and Easton. Its completion is marked by the creation of the Samuel P. Senior dam of the Saugatuck River in January 1942, and provides water to several of the nearby towns. The reservoir is surrounded by the Centennial Watershed State Forest and a small section of the Trout Brook Valley State Park Reserve on the southeast end of the reservoir. The Saugatuck Reservoir utilizes an uncontrolled spillway adjacent to the Samuel P. Senior dam that effectively limits the maximum water level. There is also a concrete levee positioned on the southeastern side of the reservoir that prevents water from flooding Trout Brook Valley.
The Burdekin Falls Dam, also known as the Burdekin Dam, is a concrete gravity dam with an uncontrolled spillway across the Burdekin River, located south west of Ayr, and Home Hill in the Shire of Burdekin, North Queensland, Australia. Built for the purpose of irrigation, the reservoir is called Lake Dalrymple. Burdekin Falls Dam is managed by SunWater. Water from the reservoir is also used to replenish downstream aquifers.
Coarse fishing a phrase commonly used in Britain and Ireland, refers to the angling for rough fish, which are fish species traditionally considered undesirable as food or game fish. Freshwater game fish are all salmonids, most particularly salmon, trout and char. Generally, coarse fish are freshwater fish that are not salmonids, though there is often disagreement over whether grayling should be classified as game fish or a coarse fish.
Maharana Pratap Sagar, also known as Pong Reservoir or Pong Dam Lake is a large reservoir in Fatehpur, Jawali and Dehra tehsil of Kangra district of the state of Himachal Pradesh in India. It was created in 1975, by building the highest earthfill dam in India on the Beas River in the wetland zone of the Siwalik Hills. Named in the honour of Maharana Pratap (1540–1597), the reservoir or the lake is a well-known wildlife sanctuary and one of the 49 international wetland sites declared in India by the Ramsar Convention. The reservoir covers an area of 24,529 hectares, and the wetlands portion is 15,662 hectares.
Tantangara Dam is a major ungated concrete gravity dam with concrete chute spillway across the Murrumbidgee River in Tantangara, upstream of Adaminaby in the Snowy Mountains region of New South Wales, Australia. The dam is part of the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro. The purpose of the dam includes water management and conservation, with much of the impounded headwaters diverted to Lake Eucumbene. The impounded reservoir is called Tantangara Reservoir.
The Serpentine Dam is a rockfill embankment dam with a concrete face and a controlled spillway across the Serpentine River, located in the South West region of Tasmania, Australia.
The River Garry in Inverness-shire is a Scottish river punctuated by two long Lochs, in the region of Lochaber. It flows broadly west to east through Glen Garry, starting in a wilderness to the east of Knoydart and ending at Loch Oich in the Great Glen, which forms part of the Caledonian Canal. There are a few tiny settlements within Glen Garry, but the only village of any size near to the river is Invergarry, at its mouth. Loch Quoich at the western end of the watercourse is dammed by the largest mass earth fill dam in Scotland, and supplies water to Quoich hydroelectric power station. Loch Garry is dammed by a much smaller dam in the gorge where the river begins its descent to Invergarry, and supplies water to Invergarry hydroelectric power station, close to the mouth of the river. Both hydroelectric schemes were built in the 1950s, with the aim of stimulating economic regeneration in the area. They have altered the ecology of the river, as both lochs were made considerably bigger as a result of constructing the dams.
The Koteshwar Dam is a gravity dam on the Bhagirathi River, located 22 km (14 mi) downstream of the Tehri Dam in Tehri District, Uttarakhand, India. The dam is part of the Tehri Hydropower Complex and serves to regulate the Tehri Dam's tailrace for irrigation and create the lower reservoir of the Tehri Pumped Storage Power Station. In addition, the dam has a 400 MW run-of-the-river power station. The project was approved in 2000 and its first generator was commissioned on 27 March 2011, the second on 30 March 2011. The construction site had been inundated in September 2010 by floods. The diversion tunnel was later blocked heaving/collapse of the hill in December 2010. The spillway was commissioned in Jan, 2011. The last two generators were made operational in March 2012.
The Breadalbane Hydro-Electric Scheme is a hydroelectric scheme in the Breadalbane area of Perthshire, Scotland. It comprises seven power stations which generate 120MW of power from the dams around Loch Lyon, Loch Earn and Loch Tay.
The Eklutna Dam, also referred to as the New Eklutna Dam or Upper Eklutna Dam, is an embankment dam on the Eklutna River about 30 mi (48 km) northeast of Anchorage in Alaska, United States. The primary purpose of the dam is hydroelectric power generation and it supports a 47 MW power plant. It was first completed in 1929 but was rehabilitated or rebuilt on several occasions over its history. Ownership of the dam and power plant is shared by Chugach Electric and Matanuska Electric.
In February 2017, heavy rainfall damaged Oroville Dam's main and emergency spillways, prompting the evacuation of more than 180,000 people living downstream along the Feather River and the relocation of a fish hatchery.
