GROUND WATER
CONTRIBUTES HIGH LEVELS OF DISSOLVED SOLIDS TO RED RIVER DURING PERIODS OF
LOW FLOW (Map Area 19)
Analyses of samples of ground water and samples from
tributaries and along the main stem of the Red River of the North showed
that during low stage and low flow conditions in March and December,
ground water contributes a large percentage of the flow. The ground
water contains significantly higher levels of dissolved solids than
snowmelt and surface runoff. Flow from most tributaries contain higher
levels of dissolved solids than the main stem. Reconnaissance sampling of
fish tissue and stream sediment
showed only trace levels of heavy metals and organic carbons.
