OutdoorMN News - Groundwater sampling planned for Groundwater Atlas of Hennepin County

The Minnesota Department of Natural Resources will collect water samples from about 90 wells in Hennepin County this summer to help create a county groundwater atlas.  
Select owners will be contacted by mail or phone for permission to sample their wells. Sampling involves measuring the depth to water and collecting a water sample for laboratory analysis. Participation is voluntary and owners will receive a report of the laboratory results.

Wells are selected based on geology, location, well depth and well construction. The samples will help the DNR create county maps and descriptions of groundwater distribution, movement, conditions, and the pollution sensitivity of aquifers. The final products will be available as printed maps, reports, and geographic information system (GIS) files available on the web.

The atlas can be used to help identify viable water sources, evaluate supply, identify recharge sources and flow, manage sustainability, guide decisions for well and septic system construction, assist in well-head protection for public water supply, and assess pollution sensitivity and likely contamination migration.

County atlases are produced in two parts over the course of several years. Part A covers the geology of the county, and was completed for Hennepin in 2018 by the Minnesota Geological Survey. Part B will expand on this information to cover the hydrogeology (groundwater) using the new Hennepin well-sampling data. The DNR expects to complete the atlas in 2021.

The county atlas program is funded in part by the Minnesota Environment and Natural Resources Trust Fund as recommended by the Legislative-Citizen Commission on Minnesota Resources. Funding also comes from the Clean Water Fund, which receives 33 percent of the sales tax revenue from the Clean Water, Land and Legacy Amendment approved by voters in November 2008.

A full description of this DNR program and status reports for atlas products is available at mndnr.gov/groundwatermapping.

      I'm not there, so I can't tell exactly what's going on but it looks like a large area of open water developed in the last day with all of the heavy snow on the east side of wake em up Narrows. These two photos are from my Ring Camera facing north towards Niles Point.  You can see what happened with all of snow that fell in the last three days, though the open water could have been wind driven. Hard to say. .

      Black Bay had great ice before but a few spots near rockpiles where there were spots of open water. It looks like the weight of the snow has created a little lake in the middle of the bay.

      On the south end...   Thanks to some cold spring weather, ice fishing continues strong for those still ice fishing.  The bite remains very good.  Most resorts have pulled their fish houses off for the year, however, some still have fish houses out and others are allowing ATV and side by sides.  Check social media or call ahead to your favorite resort for specifics. Reports this week for walleyes and saugers remain excellent.   A nice mix of jumbo perch, pike, eelpout, and an occasional crappie, tullibee or sturgeon being reported by anglers. Jigging one line and using a live minnow on the second line is the way to go.  Green, glow red, pink and gold were good colors this week.     Monster pike are on a tear!  Good number of pike, some reaching over 45 inches long, being caught using tip ups with live suckers or dead bait such as smelt and herring in 8 - 14' of water.   As always, work through a resort or outfitter for ice road conditions.  Safety first always. Fish houses are allowed on the ice through March 31st, the walleye / sauger season goes through April 14th and the pike season never ends. On the Rainy River...  The river is opened up along the Nelson Park boat ramp in Birchdale, the Frontier boat ramp and Vidas boat ramp.  This past week, much of the open water skimmed over with the single digit overnight temps.   Areas of the river have popped open again and with temps getting warmer, things are shaping up for the last stretch through the rest of the spring season, which continues through April 14th.   Very good numbers of walleyes are in the river.  Reports this week, even with fewer anglers, have been good.  When temps warm up and the sun shines, things will fire up again.   Jigs with brightly colored plastics or jigs with a frozen emerald shiner have been the desired bait on the river.  Don't overlook slow trolling crankbaits upstream as well.   Good reports of sturgeon being caught on the river as well.  Sturgeon put the feed bag on in the spring.  The bite has been very good.  Most are using a sturgeon rig with a circle hook loaded with crawlers or crawlers / frozen emerald shiners. Up at the NW Angle...  Ice fishing is winding down up at the Angle.  Walleyes, saugers, and a number of various species in the mix again this week.  The bite is still very good with good numbers of fish.  The one two punch of jigging one line and deadsticking the second line is working well.   Check with Angle resorts on transport options from Young's Bay.  Call ahead for ice road guidelines.

      With the drifting, kind of hard to tell for sure, but I'm guessing about a foot and still lightly snowing. Cook end!

      How much snow did you get on Vermilion? 
    • Mike89
      lake here refroze too...  started opening again yesterday with the wet snow and wind...  very little ice left today...
    • Hookmaster
      A friend who has a cabin between Alex and Fergus said the lake he's on refroze. He texted me a pic from March 12th when it was open and one from 23rd when it wasn't. 🤯

      I don't think that there has been any ice melt in the past few weeks on Vermilion. Things looked like a record and then Mother Nature swept in again.   I'll give my revised guess of April 21st
