The old riverbed<\/strong><\/p>\n\n\n\n

Between Keldnal\u00e6kur and the waterfall Haldfoss, the river flowed until a dam was built in 1968. The river had swept across an area of \u200b\u200babout 60 hectares and caused significant land degradation. Now the old riverbed has been re-watered, creating new habitat for salmon and trout. At the same time, there is an opportunity to reclaim the area and cultivate the land.<\/p>\n\n\n\n

By diverting a small amount of water from the river into the old channel and slowing its flow with the vermit ponds, ideal conditions are created for the hatching and rearing of juvenile trout and salmon. The vermit ponds increase the surface area of \u200b\u200bthe water, which can then be heated by the sun. The water that enters the vermit ponds will be the warmest available from the Eystri Rang\u00e1, and there is a possibility of raising its temperature even further in the ponds. Although the waste water returns to the river at Haldfoss, where the flow is low, it is unlikely to have a measurable effect on the temperature of the river as a whole. To monitor this, thermometers will be installed for precise measurements.<\/p>\n\n\n\n

Summer Construction:<\/strong><\/h3>\n\n\n\n

This summer we tackled a major project on the Lax\u00e1 River in Keldum, which marks an important step in creating new and improved habitat for North Atlantic salmon. The project involves restoring the old riverbed, which stopped flowing about 57 years ago, but now the water is flowing there again \u2013 and with it, new life has sprung up.\n\nThe first steps:\n\nWe started by damming the riverbed where it flows into Haldfoss, a spectacular waterfall at the bottom of the old channel. Next, we dug through a dam that had been built in 1968 to protect the land from erosion. This dam had blocked the flow of water for more than half a century. When we opened the water flow again, everything came back to life \u2013 the water began to flow the more than two kilometers from the dam down to Haldfoss.\n\nThe old riverbed comes to life:\n\nThe water now flows freely down the riverbed, forming a beautiful lagoon at Haldfoss. This lagoon is ideal for salmon fry, which are now protected and able to grow naturally. We also plan to add more ponds along the way. The riverbed comes to life in Keldur<\/p>\n\n\n\n

When we opened the water flow again, everything came to life \u2013 the water began to flow the two kilometers from the dam down to Haldfoss. The temperature where the water enters was 9.2 degrees in early July, and after it had flowed along the old riverbed for two kilometers, the temperature had reached 12.6 degrees.<\/p>\n\n\n\n
