The Minnesota Department of Natural Resources Aitkin area fisheries staff has finalized the assessment schedule for the 2017 field season.

The DNR conducts fisheries surveys and assessments on a regular basis to monitor changes in fish populations, and to determine if management strategies have been effective.

Survey frequency varies on each lake based on ongoing management evaluations, angler use and current staffing levels. Large lakes with heavy use are scheduled more frequently than small remote lakes. Lakes that are stocked on a regular basis are also sampled more frequently to assess stocking success and monitor growth rates. Staff then review the data and incorporate it into individual fisheries lake management plans. The plans identify goals for key species in the lake and outline specific management activities.

After ice is out through May: 

  • Round Lake (01-0137) – targeted survey with trapnetting and electrofishing for walleye and Northern Pike (April).
  • Cedar Lake (01-0209) – muskellunge netting (April/May).
  • Cedar Lake (01-0209), Fleming Lake (01-0105), Hammal Lake (01-0161), Round Lake (01-0023) and Savanna Lake (01-0014) – bass electrofishing. (Mid-late May)
  • Ripple River (M-113-030) – walleye spawning habitat evaluation and measurements.

June through October (Dates subject to change):

  • Rock Lake (01-0072) – standard survey with habitat evaluation (June 12-16).
  • Round Lake (01-0023) – standard survey (June 19-23).
  • Rat lake (01-0077) – standard survey (June 26-30).
  • Round Lake (01-0137) – standard survey (July 10-14).
  • Dam Lake (01-0096) – standard survey (July 17-21).
  • Spirit Lake (01-0178) – targeted survey, gillnetting for walleye evaluation (July 24-28).
  • Savanna Lake (01-0014) – standard survey (July 31- Aug. 4).
  • Fleming Lake (01-0105) – standard survey (Aug. 7 -11).
  • Cedar Lake (01-0209) – standard survey (Aug. 14-18).
  • Hammal Lake (01-0161) – standard survey (Aug. 21-25).
  • Sissabagamah Lake (01-0129) – targeted survey, gillnetting for walleye evaluation (Aug. 28 – Sept.1).
  • Spirit Lake (01-0178) – targeted survey, electrofishing for walleye (Aug. 28 – Sept.1).
  • Big Sandy Lake (01-0062), Farm Island Lake (01-0159) – targeted survey, electrofishing for walleye (late September – early October).
  • Taylor Lake (01-0109) – standard survey (Oct. 2-6).
  • Two River Springs (M-122) – natural reproduction check (mid-late October).

Additionally, Hammal Lake (01-0161), Fleming Lake (01-0105), Farm Island Lake (01-0159), Round Lake (01-0137), Dam Lake (01-0096), and Savanna Lake (01-0014) will receive additional nearshore sampling using seines and backpack electrofishing to help calculate an index of biotic integrity (IBI), which incorporates the catch information from game fish and non-game fish from these nearshore surveys as well as the standard surveys to gage the overall health of the fish community.

The information collected in 2017 will be available as a lake survey report in the spring of 2018 on the DNR website at www.mndnr.gov, or from the area fisheries office.  For more information, contact Aitkin Fisheries office at 218-429-3031, [email protected], or in writing at MN DNR, Area Fisheries, 1200 Minnesota Ave., Aitkin, MN 56431.

The DNR’s summer fieldwork activities are largely funded through the sale of fishing licenses and the Federal Sport Fish Restoration Act. The number of surveys vary from year to year as funding and staffing levels change.

      I might have missed a guess, but here are the ones that I noted:   JerkinLips – March 27th, then April 7th Brianf. – March 28th Bobberwatcher – April…. MikeG3Boat – April 10th SkunkedAgain – early April, then April 21st   Definitely a tough year for guesses, as it seemed to be a no-brainer early ice out. Then it got cold and snowed again.

      Sturgeon Fishing is Hot

      By LakeofthewoodsMN · Posted

      On the south end...   Lots of ice on the main basin, but it is definitely deteriorating.  Some anglers have been fishing the open water at the mouth of the Rainy River in front of the Lighthouse Gap.  The rest of the basin is still iced over. Pike enthusiasts caught some big pike earlier last week tip up fishing in pre-spawn areas adjacent to traditional spawning areas.  8 - 14' of water using tip ups with live suckers or dead bait such as smelt and herring has been the ticket.  Ice fishing for all practical purposes is done for the year. The focus for the basin moving forward will be pike transitioning into back bays to spawn,  This is open water fishing and an opportunity available as the pike season is open year round on Lake of the Woods. The limit is 3 pike per day with one being able to be more than 40 inches. All fish 30 - 40 inches must be released. With both the ice fishing and spring fishing on the Rainy River being so good, many are looking forward to the MN Fishing Opener on Saturday, May 11th.  It should be epic. On the Rainy River...  An absolutely incredible week of walleye and sturgeon fishing on the Rain Rainy River.     Walleye anglers, as a rule, caught good numbers of fish and lots of big fish.  This spring was one for the books.   To follow that up, the sturgeon season is currently underway and although every day can be different, many boats have caught 30 - 40 sturgeon in a day!  We have heard of fish measuring into the low 70 inch range.  Lots in the 60 - 70 inch range as well.   The sturgeon season continues through May 15th and resumes again July 1st.   Oct 1 - April 23, Catch and Release April 24 - May 7, Harvest Season May 8 - May 15, Catch and Release May 16 - June 30, Sturgeon Fishing Closed July 1 - Sep 30, Harvest Season If you fish during the sturgeon harvest season and you want to keep a sturgeon, you must purchase a sturgeon tag for $5 prior to fishing.    One sturgeon per calendar year (45 - 50" inclusive, or over 75"). Most sturgeon anglers are either a glob of crawlers or a combo of crawlers and frozen emerald shiners on a sturgeon rig, which is an 18" leader with a 4/0 circle hook combined with a no roll sinker.  Local bait shops have all of the gear and bait. Up at the NW Angle...  Open water is continuing to expand in areas with current.  The sight of open water simply is wetting the pallet of those eager for the MN Fishing Opener on May 11th.   A few locals were on the ice this week, targeting pike.  Some big slimers were iced along with some muskies as well.  If you like fishing for predators, LOW is healthy!
