Hydrologic Conditions Report October 2014
This is the seventh and final installment of the monthly Hydrologic Conditions Report for 2014. For comparative purposes please reference the previous reports at: http://mndnr.gov/current_conditions/hydro_conditions.html
• October 2014 precipitation totals were generally below-normal across most of Minnesota. Monthly rainfall totals fell short of historical averages by one to two inches in most locations. Areas of relative wetness were reported in some southeast Minnesota counties where October rainfall totals topped historical averages by an inch or more. As of early November, the U. S. Drought Monitor indicated that Abnormally Dry conditions existed over one-half of Minnesota's landscape due to late summer and autumn precipitation deficits. Despite the dry July-through-October period, seasonal precipitation totals since April 1 remained above historical averages for large sections of Minnesota. Below-normal rainfall during the late summer and early autumn slowed the record-setting pace established early in the growing season.
• Following September Above Normal/High Flows for the majority of the state, October flows predominately dropped to Normal conditions. West-Central Minnesota still has some watersheds Above Normal and the Northeast is still seeing Below Normal conditions with the Vermilion River Watershed (Major Watershed 73 & 74) an exception, dropping into the Low Flow category. In the Northwest the impacts of an approaching winter are being felt with seasonal gages no longer being monitored and backwater caused by ice further downstream impacting monitoring along the Red River.
• Most of the lakes in the state stayed steady or decreased very gradually by the end of the month. When comparing October lake levels to their entire historic record, a fifth of the statewide gauged lakes reporting in were still at their Above Normal or High percentile range. Eight out of these 24 selected lakes remained at Above Normal or High September percentiles, reflecting the staying power of the 2014 season-to-date precipitation amounts. Five lakes were at the Below Normal percentile. At the end of this month, White Bear had similar water levels as its lake levels in late October 2008.
• Groundwater levels remain at or above normal levels when compared to monthly historical averages for
the majority of the state. There was little movement from September to October’s water levels but several of them did decline. The only water level to increase was the Mt. Simon well located in Hennepin County. The majority of the central part of the state is still above normal while the majority of the northern aquifers are at normal water levels for the month. Jackson County saw the only low indication in its buried artesian well.
The information in this report is provided by DNR through long term programs committed to recording and tracking the long term status of our water resources. The current conditions of precipitation, stream flows, lake levels and ground water levels in this report provide valuable information for natural and economic resource management on a state, county and watershed level.

* Percentile ranking based on mean daily flows for the current month averaged and ranked with all historical mean daily flows for that month. A watershed ranked at zero means that the present month flow is the lowest in the period of record; a ranking of 100 indicates the highest in the period of record. A ranking at the 50th percentile (median) specifies that the present-month flow is in the middle of the historical distribution.
