Water Temps and Update

15 posts in this topic

Hit two lakes this morning and fishing was alright. Potato had 40 degree surface temp and Little Sand had 42 degree surface temp. That means we're pretty close to hitting the magic number of 39 degrees when water is most dense and it all mixes together. Not to mention it's an indication that ice fishing is in the near future. Mud lake on the north side of long re-opened today, but Daisy lake, a mudhole north of Nevis, was frozen over. It's hard to decide to wish for ice or warm weather to continue fishing in the boat.

Caught walleye, northern and smallies on both Potato and Little Sand, 16-22 feet was the magic number and I was using redtails and shiners. Anyone else still fishing?

I fished the Brainerd area yesterday and this morning managed 1 eye 1 bass and a couple dandy pike working jigs with grubs slow in deeper water. I may be traveling to Long one time next weekend I will have to check back to you with temps of the water if you still getting out next week.

We're supposed to have moderate temps for the next couple days, you'll be able to get out on Long no problem next weekend. What will you be fishing for?

We usually go Pike and Bass fishing, but that lake we were fishing in Brainerd wasn't suppose to have eye's in it and sure enough the pike and bass were real slow the first fish I caught jigging a 4 inch grub was a walleye so I'm think ill try hard to get some eyes out of Long. My buddies dad pulled a fat 31" eye opening weekend in 7 Fow lindy rigging a leech. What do you think would be best to try to go after some big eyes or pike?

i hit fish hook on the 12th of Nov in the evening for about 3 hours, i had my daughter and granddaughter with me not to mention my good friend lippy. the temp was 42 degrees and i managed to pull a nice 28 incher and my daughter had to beat me with a 30 incher and a 15 incher. she is from washington state and i had to take her to the airport the following morning or we would of been out there again, oh ya the reason she was back was to go deer hunting with her dad and she shot a nice 8 pointer opening morning, so her trip was very successful and she will have memories of this forever as so will i. besides i do want her to come back ya know

Nice fish, those two are sure to get you back on the water next hunting season.

I was out yesterday for about an hour and half on 8th Crow Wing. Had to break through a skim of ice to put the boat in. Water temp was 38.

I received an email from a member of the Little Sand Lake association this morning. They've been monitoring water temp and oxygen throughout the summer and the data is pretty interesting. Here's the email (remember, water is most dense at approximately 39 degrees.)

"Jason,

We were on the water doing our DO/Water Temperature monitoring again today (November 17th) for the final time of the season. The water temperature ranged from 40.8 on the surface to 41.1 at 71 feet of water. The dissolved oxygen ranged from 10.67 ppm on the surface to 9.96 ppm at 71 feet of water.

So the lake has turned over since the last time we did the monitoring on October 25th. On October 25th the dissolved oxygen was at 5.75 in 45 feet of water and dropped to 0.19 in 46 feet of water."

Wow great info on the Dissolved Oxygen. Seems like the only true way of knowing whether the lake has turned or not. But I'm suprised it took that long this year to turn. I was under the impression that most lakes in the area would be turned over by mid October. Is this late turn over typical?

There's an infisherman article by Corey (Toad?) about his thermocline study on Gull Lake (google it). I really enjoy his articles, he always has great info. Anyway, the water at the surface was 54 F when it mixed and he could no longer "see" a thermocline or detect one with temperature readings at different depths. This was happened on October 6th.

Could the difference just be due to lake characteristics (clarity, depths, size)?

All of the info in this thread can be useful to every angler. I fished more for fall walleyes this year than I have in my entire life. Fishhook, Potato, and Big Sand were all successful lakes for me. It helped that I actually had the lakes at my fingertips during the entire fall. The 3 biggest walleyes of my life were all caught this year led by the 29.5" posted as my avatar. As my username would indicate I am a bass guy first and foremost, however, I have a huge walleye itch now and will continue to fish for them in spring and fall when the bass have slowed down. I never really cared for walleye fishing in the past, but it helps when you actually get out and educate yourself and try new things that help you catch fish.

My only regret is not having figured this out earlier. I really think I have been cheating myself in the past by limiting myself to fishing bass exclusively. Don't get me wrong, bass fishing is still #1 on my list. I just will look forward to walleye fishing more often in the future now that I somewhat know what I am doing.

Open water fishing in November was never really a thought in the past. Because of the ice forming on the lake recently, I FINALLY just winterized my boat yesterday.

Time for ice fishing. frown.gif

Turnover can happen multiple times. All that is needed is a constant water temp - no thermocline. Smaller or shallow lakes will turn a lot easier than deeper lakes. You could get a turnover when surface temps reach 54 deg. as the water cools and reaches the thermocline temp. You could also get a turnover at 39 degrees as the surface water warms with warmer temps. It all depends on weather patterns. If you have a steady drop in temp in the fall and a steady rise in the spring you will not see as much mixing. With the temps we've had this season water temps can fluctuate a lot more.

eyefever-

You're right on. There's much more to consider than simply waiting for the water temp. to hit 39. Especially on larger bodies of water that are impacted more by wind. The 39 degree mark is simply when water becomes most dense and on the small lakes around here, which are numerous, that number indicates when the water becomes "thick" in the fall. LOVE to fish muskies during this period (might still get out tomorrow).

The process of fall turnover can start in August and pinpointing an exact date to the phenomenon typically occurs when anglers see weeds floating, a "muddier" appearance to the water, etc. Yet that isn't necessarily turnover and every lake doesn't experience those effects. It's more of an on-going process than a rapid, finite change.

I received some graphs from the Park Rapids Fisheries office with the accumulated data from the dissolved oxygen/water temperature study on Big Sand and Little Sand. It's formatted in powerpoint and is interesting to see. If anyone wants me to email a copy of it, just let me know.

Any more updates on the ice conditions with the cold temps?

Long still has open patches. I hear that some people are beginning to straggle out. I'm hitting a small pond Saturday and anticipating the ice will be safe, but you never know.

A dog went through on Loon Lake this week and was rescued. An eight point buck drown on another, but can't recall which lake it was. Both were a few days ago, we had -1 this morning.

      J-Roy,  I use UL rod and 4 lb a lot when throwing jigs. I have found that the lighter the jig head, the more fish bite and the more you hook. Wind will mess up using light jigs though. When fishing heavy jigs, cranks, top water or spoons, I use heavier line and rod. If fishing weeds need heavy line as well.   Hook ups/bites is much higher with lite jigs. I missed about 50% of hits yesterday using 1/2 oz head. Landed about 90% of hits a few days ago when using 1/8 oz head. Tough to fish 1/8 oz on even 8 lb line so I stick with 4 lb .

      We've got the old Lakemaster chip in our Lowrance 10" unit (circa 2008-ish, I think).  The Lowrance is the generation before the HDS, but I forget the exact model.  Since getting that Lakemaster chip, Lakemaster was bought by Humminbird and their chips are now only compatible with Humminbird  units.  You might be able to find a used chip somewhere, but be sure it's from before the Humminbird acquisition.   Navionics is the only other option for Lowrance that I know of. Regardless, there have been several 1-foot soundings done in the recent past, so be sure that whatever you get has that level of detail and you should be satisfied.   There are several old threads on GPS chips for LOTW...use the search box at the upper right of your browser and type in "LOTW chip" (without the quotes).

      Also noticed or heard you say your using 4 lb. test line. Is that correct?? We used 10-12 mono and 15  flouro.  We sure love this lake. Can't sleep for next three weeks waiting to head up there LOL

      ago ·  Hey guys, I'm new to this site. Trying to learn more about this lake. My brother and I fished there last July 9-16-2016. We did good on all species, especially like and walleye. We had several rallies on smallmouth, but never put a solid pattern together. My brother had a 4 and 5 lber. On perch shad rap. I caught many 1-1/2 - 3 lbers on uvibe speed craws. Suspending jerkbaits caught all species well. I've been checking this site and Mr. Johnwis has some great info and video. If any of you out ther could help us get on them big smallies, we would greatly appreciate it. We're from southwest Louisiana and we'll be staying at island view lodge July 22-29 . Thanks and this is a great site

      In my eyes anywhere on the Rum is great for smallies. So far this year everytime I have been out the levels have been great even after all the rain we had just had to wait a couple days and the water was great. I put in at the Anoka fair grounds and travel up river

      (Too much mercury may affect a child’s behavior and lead to learning problems later in life.) That would explain some of the backwoods people     All jokes aside I would limit it to one serving a month for being pregnant or breast feeding for Bass, Catfish, Trout, Walleye, northern like they say   "Young children (under 15 years old) and fetuses are more sensitive to mercury. Too much mercury can cause lasting problems with understanding and learning. But studies show children benefit developmentally when moms eat fish low in mercury during pregnancy.
