Stream hydrology
The Anoka Conservation District conducts stream hydrology monitoring on streams, rivers, and a few ditches throughout the county. Hydrology is the study of water quantity and movements. Records of the quantity of water flowing in a stream helps engineers and natural resource managers better understand the effects of rain events, land development and storm water management. The data is used for tracking and predicting flooding, engineering solutions to flooding problems, calculating pollutant loadings in streams, and computer modeling.
Most of our stream hydrology monitoring is done with electronic devices that record water levels every four hours, and are periodically downloaded. We use the WL, Ecotone, and WM series of devices from Remote Data Systems, Inc. We install the gauges at ice-out in spring, and only pull them out of the stream when ice formation threatens to freeze them into the streams in the fall. Each year we survey the gauges so the readings correspond to sea level elevations. At some sites, we have determined rating curves (mathematical relationship between the water level and flow), which allows us to estimate flow from the water level data.
