Minnesota Department of Natural Resources Division of Ecological and Water Resources Hydrologic Conditions Report Previous reports at: http://mndnr.gov/current_conditions/hydro_conditions.html Minnesota had above normal precipitation in, with notable exceptions in the northwest and far southeast. The preliminary statewide precipitation total is 5.15 inches or 1.71 inches above the long term average. This is high enough to be the 11th wettest August on record statewide back to 1895. There was a very wide range in precipitation totals in the state, from over thirteen inches in the Redwood Falls area, to under an inch in the far southeast. Departure from normal ranged from two to six inches above normal for southwest, central and northeast Minnesota and two to three inches below normal in the northwest and southeast. Looking at the Meteorological Summer from June to August statewide average precipitation finished at 11.57 inches or.42 inches above normal. The last time there was an average statewide summer precipitation total below average was in 2013. The preliminary statewide average temperature for in Minnesota was 64.2 degrees or 2.1 degrees below average. tied with 2009 as the 24th coolest August on record going back to 1895. The average maximum temperatures were ranked as the 16th coolest on record. The warmest August maximum temperature found was 93 degrees on August 1 at Granite Falls, with the coldest minimum temperature of 30 degrees at Embarrass on August 24 and 25. Looking at the Meteorological Summer from June to August statewide average temperature was very close to the long term average at 66.2 degrees or one tenth of a degree below the long term average. This was the coolest summer since 2009. The U. S. Drought Monitor map released on September 5, depicts 17 percent of the state in the Moderate Drought category, mostly in northwest and north central Minnesota and a small part of southeast Minnesota. This is about the same since early August. 25 percent of the state is in the Abnormally Dry category, a bit of a decrease since early August. Last year at this time there was only a small area of Abnormally Dry conditions in southwest Minnesota. About half of the indicator gages were ranked at or above the 75 th percentile. Some watersheds in the northern half of that state are at below normal flows. When comparing received lake levels to their entire historic record, 54% of these lakes were in the Normal percentile, but 35% were Above Normal or High percentiles, and 11% Below Normal or Low. So far, 59% of the gaged lakes were above their average lake level of the entire historic record, 16% at their average, and 25% of the lakes were below their average lake level. Over 57% of these above average lakes reported elevations more than ½ foot higher than their average. A large number of lakes had increased lake levels in the last few weeks of August after precipitation events. Looking at only August lake level comparisons, four of the 24 selected lakes with information in this report showed Above Normal percentiles and five at High percentiles. Two lakes in the Northwest were at Below Normal or Low percentiles, with Swan Lake coming back from a drawdown. Over half of the lakes experienced a large increase in percentile ranks since July 2017. Groundwater levels in show average to above average measurements throughout much of the state. For sites where data was provided, groundwater levels were at normal (50%) to above normal (75%-90%) or high water level (>90%). More data for groundwater monitoring sites would be needed to determine if this was a regional or statewide pattern, however, higher than average groundwater levels were found throughout Central and Eastern regions of the state. Of note, there are several water table and buried artesian wells in Western Minnesota showing lower than average water levels mimicking water level patterns in July 2017. 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.
