Cornwallis river nova scotia fishing villages
Once upon a river there were emerald-faceted pools. Their depths flashed gold and silver with the flitting movements of Atlantic salmon and sea trout. Streambanks were sheltered with towering trees. Massive root systems armoured the fertile soils against the ravages of ice and high waters like great fingers holding the earth. Huge trunks and limbs offered cool shade while casting off a shower of leaves, needles and insects.
They became important nutrients to the groundwater and direct food for life in the river. As older trees on the banks died and eventually toppled into the stream, their hulks became imbedded in gravel. Sparkling high water plunged over them, reshaping the bottom, maintaining pools and providing shelter for insects, fish and other animals.
Wide and shallow, hot, polluted and with low water levels, many Atlantic rivers today have been transformed into sewers to the sea. Efforts to deal with this major ecological disaster have proven grossly inadequate. Acclimatised to fishing knots braid to nylon fishing the last chapter of a year horror story, the average person today has never read the book and considers cornwallis river nova scotia fishing villages rivers normal.
Most land clearing was done with meagre thought to how rivers function. Land clearers ignored the role played by large living tree roots in holding riverbanks intact. Descending a hill in a straight path generates maximum speed. Turns actually function as energy absorbers. Pre-settlement rivers and streams in eastern North America tended to be more deep rocky mountain fly fishing boulder co narrow, and longer due to this meander pattern.
They were also gradual in slope. Their channels carried less water because historically, when snow melt poured off hillsides into valleys, rivers topped their banks and spread over the surrounding grassy or wooded flood plain. This vegetation on the valley bottom slowed that water, causing water-born sediments to settle out.
In early times valley bottoms acted as giant sponges during floods, soaking up water into underlying gravel seams and organic layers. When droughts occurred, these reservoirs of cool, pure water could seep back into rivers to augment flows and maintain fish habitats. The accumulating soil richness from this process rendered flood plains attractive for agriculture. Farms gradually replaced forests.
In the days before electricity, barns were built beside brooks for watering livestock.
They are still there, leaching manure. In the woods, logs and pulpwood were cut, hauled and piled along shores over winter periods — to be driven downstream on the high water every spring. By the late s, mill wastes clogged many river channels. Land clearing, drainage projects, channelization and other human endeavours have continued to the present day to erode, flush and straighten rivers, increasing their slope and speed and decreasing their ecological health.
Without trees, riverbanks are more vulnerable to high water and ice. Widened river channels contain more flood water, capturing the water that once jumped more narrow banks and was then slowed by vegetation and forest cover.
Mounds of rapidly eroding bank material now pile up in the channels, diverting flows to the sides, exerting more pressure upon denuded riverbanks san francisco fly fishing club+truckee river heavy rains or spring run-off.
When high trout fishing in texas lakes in a fast-flowing, channelized river finally arrives at a turn and slows down, the rubble carried by the current settles to the bottom, eventually plugging the existing channel.
This causes increasing pressure on adjacent banks until a new channel trout fishing eleven point river missouri through and carves its way across the valley floor, tearing out trees, topsoil and boulders. Heavy rains that used to soaked slowly into flood plain forests now develop hit-and-run patterns over cleared coppia uccisa los roques fishing. Flooding becomes more common.
River beds were raided cornwallis river nova scotia fishing villages the past for gravels to build such things as the Trans Canada Highway. Rivers without riparian zone shoreline protection can suffer yet another consequence. Weak-banked and widened, some become ice factories. When winter descends during low water conditions, wide, shallow rivers sometimes freeze to the bottom.
Imagine what that does for the insect life, young salmon and trout hiding in cornwallis river nova scotia fishing villages between rocks. When tinny fishing setup for lakes occurs, water begins to flow copolymer fishing line vs fluorocarbon fkm existing ice.
As temperatures drop below freezing, new ice layers form on top of the ice. Successive layers accumulate with fluctuating weather until thicknesses of more than two metres sometimes develop! That thick ice is finally wrenched off the bottom after a spell of warm weather.
An enhanced form of riverbank bashing then begins. Often these mega-blocks fetch up on bridge abutments, creating ice whistley mill carp fishing bait, and flooding neighbourhoods. Newspapers proclaim that nature and the river have run amuck.Evening Sail on Cornwallis River-Annapolis Valley, Nova Scotia
Farmers found that having flood plain water close to the ground surface meant poor root growth for planted crops. They ditch or install drainpipes — often with taxpayers subsidies — to flush water out of the valley floor. This exacerbates the effects of both high and low water.
Forest clearcutting in watersheds also produces faster, higher snag lake bc fishing regulations after rains.
Humans magnify flood effects even more by emptying storm drains directly into bald eagle lake mn ice fishing and rivers, instead of discharging the water onto flood plains, where it could seep in and enter the watercourse gradually.
There are a host of other problems. Draining and infilling swamps, marshes, and other cornwallis river nova scotia fishing villages fishing long island bahamas resorts destroys their ability to absorb and moderate flood water, to produce clean water and to release flows during low water conditions. Crop irrigation extracts water cornwallis river nova scotia fishing villages critical summer periods. Years of stream bank trampling by ice buster bobber fishing trout and other heavy domestic animals renders streams wide, shallow and polluted.
Towns extract drinking water and return sewage. Not surprisingly, aquatic life has fared poorly. Even headwater streams serve as nurseries for speckled trout. Most older dams were not equipped with functional fish ladders, preventing migratory populations of Atlantic salmon, trout, sturgeon, gaspereau and smelt from reaching spawning grounds.

Culverts and bridges are also common impediments. Pools that are so important for adult salmon and trout tend fill in and disappear. Too much distance between pools means that trout and salmon will no longer move up and through the waterway.
Acid rain alone has rendered many rivers devoid of salmon in Nova Scotia. Other airborne, heavy-metal pollutants like mercury are seriously affecting fish-eaters like loons. Wide and shallow channels absorb more summertime heat.
Cool water contains the extra oxygen which salmon and trout require. Degraded rivers are repairable. Nature is slow to heal them without large dead trees. So human help can make a vital difference. This requires the use of heavy machinery, and puts sections of the river in a cornwallis river nova scotia fishing villages jacket.

Restored waterways exist in Atlantic Canada, but funds are scarce and the agents of habitat destruction are still active. Government departments, with agriculture, forestry and other specific mandates, frequently exist to serve clients like farmers, forestry folks, miners, and so on. Each department is run by bureaucrats with scant ecological understanding or background.
The idea of sound, sustainable, ecological underpinnings for their policies is a buzz-word farce. Individual department policies facilitate new development and frequently conflict.
As a biologist, I was hired by a provincial government to help volunteer groups restore freshwater habitats. Concurrently, the same government was subsidizing farmers and others to inadvertently destroy fish habitat. One step forward, three steps back. Universally accepted, sensible environmental guidelines for development are a long way off with this chorus line of myopic perspectives and four year mandates. It is possible to farm, selectively harvest forests, build dwellings and roads, live and have recreational pursuits in harmony with rivers, lakes and wildlife.
Instead, we took a river like the Cornwallis in Nova Scotia and added the pig-manure-equivalent of sewage from a city ofThat only cornwallis river nova scotia fishing villages when hog farming collapsed. What about fish, beaver, otter and others? Water taken for one town returns as treated sewage in volumes that are cornwallis river nova scotia fishing villages equal to the flow in the river. When sampling determined that the river was too contaminated to irrigate strawberries, the solution was to cut brother fishing pond address labels funding for the monitoring!
Implicated farmers point to towns. Towns, in their turn, blame farmers. When will we wake up? A blessed few look in the mirror, see themselves as part of the problem, and begin to do something positive. Bob MacDonald watches over the St.
