Runoff-fed

Describing a water source, typically a body of water (lake, river, stream, etc.), primarily or significantly supplied by surface runoff. Runoff is water from rain, snowmelt, or other precipitation that flows over land rather than seeping into the ground. The quality and quantity of runoff-fed water are directly influenced by factors like land use, vegetation cover, and the intensity and duration of precipitation events. These water sources are often subject to seasonal fluctuations in volume and can be vulnerable to pollution from agricultural chemicals, urban pollutants, and erosion from deforested lands. They play crucial roles in ecosystems and are commonly utilized for human purposes like irrigation, drinking water supplies, and recreation.

Runoff-fed meaning with examples

• The pristine mountain lake, entirely runoff-fed by melting snow, provided exceptionally clear and cold water. Its purity made it an ideal habitat for trout and a popular destination for hikers and campers. Conservation efforts focused on protecting the surrounding watershed to prevent pollution and maintain the lake's delicate balance. The lake's ecosystem thrived because of the natural filtration of the surrounding forest.
• During heavy rainfall events, the river, a runoff-fed artery for the region, experienced rapid increases in flow and sediment load. This made it challenging to navigate and potentially overwhelmed the local water treatment plant. Understanding the impact of urbanization on the river was key to the flood control strategy. The increase in flow was natural from the runoff, as excess water flowed to the river.
• The small creek, a runoff-fed stream originating in a nearby forest, was vital for supporting local wildlife. Animals depended on the creek for drinking and breeding. The creek's water quality was directly linked to the health of the surrounding woodland, and there was concern about the effect that the construction project at the edge of the forest would have on the runoff entering the water source.
• Farmers in the valley relied on the runoff-fed irrigation ditches to water their crops, depending on snowmelt and summer rainfall. The ditches created a system dependent on the amount of runoff. They were very concerned by the prospect of drought, which would jeopardize their harvests. The consistent supply of water from these runoff-fed ditches was essential for agricultural success.
• The town's reservoir, a critical resource, was largely runoff-fed, with its levels fluctuating according to rainfall. The reservoir was crucial for drinking water supply and emergency services. The reservoir's capacity was carefully monitored to ensure an adequate supply throughout the year and during drought. There was concern about the impact of deforestation in the watershed.
