North Lake public access project starts next summer
By Don Behm of the Journal Sentinel
Nov. 6, 2009 4:23 p.m. | Construction of the first public access to North Lake in Waukesha County is scheduled for summer 2010, a state Department of Natural Resources official said Friday.
The 437-acre lake is the largest water body in the county without public access, said Jim Ritchie, DNR public waterways access coordinator.
The DNR purchased the former Whitey Krause property on Reddelien Road in the Town of Merton for $1.125 million in 2005. The 6.5-acre parcel includes 233 feet of frontage on the northwest shore of the lake, Ritchie said.
Construction of the access site, with boat ramp, dock and parking lot for 16 vehicles and trailers will cost $475,000.
"Development of this property will ensure that anglers and recreational boaters have permanent year-round public access for open water and ice fishing on North Lake," Ritchie said. "There's been a strong demand for access to this lake for many years."

Great weekend ahead.
There's a great weather outlook for the next couple days, and you should consider hitting the water. The warmer temps will bring a variety of fish into the shallow areas, especially those with rock or sand bottoms, in the early afternoon.
Live bait is always a good option this time of year, especially suckers and shiners, but don't over look crankbaits. A thinner profile bait that wiggles instead of wobbles, always seems to catch some decent fish when the conditions are like this this late in the year.
Look for rocky areas adjacent to deep water. The fish will be laying on the rocks, on patrolling the bottom transition just next to them.
Good Luck

Still time to get out....
The weather outside is just right for musky fishing on the inland lakes, and the walleye run will be biting on the Rock River.
Still plenty of time to get out in the boat. Give me a call if you'd like a last chance to hit the water this season.

Fishing Report: October 4, 2009
Well its fall, and I have some good news.
Water temps are peaking out below 60 degrees in the afternoons. Okauchee, Oconomowoc and Lac Labelle all clocked in the high 50's late today, which means now is the time to hit the water for some musky fishing. The bite has been a bit slow, but certainly steady. Two large fish were caught on Okauchee in the last week, and we've had numerous reports of high 30's and low 40's fish coming to the boat.
Some advice: The lack of rain this season allowed the weeds to grow deeper than is typical for our area. Likewise, a fair number of fish are being caught in deeper water than is typical for this time of year. Trolling has been producing, especially in areas with baitfish in 18-25 feet of water. Good use of your electronics is essential right now.
Look for the bite to move shallower and into the available green weeds, but don't over look rock bars adjacent to mid depth weeds, especially on warmer sunny afternoons, as fish will move up to warm up and digest food.
Fishing with suckers is never a bad idea this time of year. We have suckers and custom quick strike rigs in stock right now.
-----
Other happenings:
Smallmouth fishing will pick up on the area lakes, and now is the time to chase down a trophy sized fish with live bait. Slip-sinker rigs with walleye suckers or large shiners drifted or trolled very slowly around the deep edges of structure can surprise you. If you find fish, you'll very likely be over a good school of them. fish that area hard, and pay attention to your electronics. Subtle bottom changes will concentrate fish.
Walleye fishing has been slow, but is starting to pick up in the Dells and along the Jefferson Dam to Blackhawk Island stretch of the Rock River. Water is seasonably low this time of year, so watch your prop, but look for fish in the current, in the shallow water near deeper holes. They will likely be actively feeding, rather than holding in the deep water. Jig and Minnow, Lindy rigs or jig and twister are good producers.

Fishing Report 9-22-09
The water is in the mid to upper 60's on most lakes in our area. Weeds are still green, but showing some signs of thinning out and the algae blooms are starting to clear up. There are schools of bait in both deep and shallow water, both of which are drawing attention from the gamefish right now.
Largemouth are holding along clumps of weeds on the shallow weed flats. Others are still hanging along the deeper weed edges. Smallmouth are relating to weed clumps near or adjacent to rocky and sandy areas with a drop off. The deeper fish will bite best when they make a move into the nearby shallow water, typically something they will start to do a couple times a day. When the water and air temperatures begin to cool down some more, fish will use rocky areas in the early afternoons.
Your best lure options right now are wacky worms, large jigworms, skirted grubs, jig/chunk, texas rigged plastics or lipless crankbaits. Smaller, wide wobbling crankbaits can also produce. Wacky worms and skirted grubs are great around the rocks. Jigworms, texas rigs and jig/trailers are great around the scattered weeds. Lipless crankbaits are great in both areas. Browns, greens, orange or black are usally the best colors for plastics (pretty much as they are all year) but white, shad, bluegill or silver colored crankbaits can really produce.
Walleye: Stick with live bait unless fishing over submerged weeds in the evening when you should consider throwing minnow-baits like rapalas and rouges. Look for walleyes to be in the sandgrass or in breaks in the weeds in 10-15 feet. Some fish will be deeper or shallower on our local lakes, but the best approach to locating fish is to slowly troll with a slip-sinker or lindy rig with a big minnow.
Northern: Most northern caught this time of year are caught while targeting other species, especially bass and musky. But they can still be caught and in good numbers. For bigger fish, try Deep diving crankbaits in bluegill, perch or white/shad color patterns. Hot N Tots, wiggle warts and the rapala deep divers are my favorites for trolling, while Norman D-22's or lipless crankbaits are better options for casting.
Musky: The fish are starting to make fall transitions, but the action is still a little slow. I'd expect that to make a rapid change after this week. Most fish are being reported from 10-15 feet of water. Casting bucktails, gliders, swimbaits or jerkbaits all will draw some attention, but don't forget to keep a sucker or two out on a quick-strike rig. Many fish that follow a bait to the boat will turn on for the sucker hanging nearby.
Good Luck

Fall Runs
From the DNR:
50 places to fish from shore within 60 minutes of Milwaukee
MADISON – Like clockwork, it’s that time of year when trout and salmon begin staging in the river mouths and harbors – ready to run the course back to their spawning grounds.
And anglers looking to fish these spectacular runs can visit the new Lake Michigan Fall Fishing page of the Department of Natural Resources Web site for informational resources that highlight 50 places to fish from shore within 60 minutes of downtown Milwaukee.
“No need to put the fishing gear away just because summer is nearing its end,” says Brad Eggold, Department of Natural Resources Southern Lake Michigan fisheries team supervisor. “The spawning runs represent tremendous opportunities -- they’re close by, you don’t need a boat, and you have a high chance of success.”
“We developed these materials because we wanted to make it as easy as possible for anglers to find places to fish during these events.”
The resources include:
* A downloadable pocket-size brochure that lists the 50 locations and the dominant species available, and, and gives directions, distance and driving time from downtown Milwaukee. Printed copies will be available in the coming weeks at DNR service centers in southeastern Wisconsin.
* Google map showing photos of the fishing sites and detailed driving directions
* Advice on the fishing gear to use and the best times to go.
More about what anglers need to fish the spawning runs
Timing is everything, and although heavy rains can sometimes trigger earlier runs, this schedule gives anglers a good idea of when the runs can begin, peak and end:
* Chinook salmon – Sept. 1 to Oct. 15, peak in late September
* Coho salmon – Oct. 1 to Nov. 15 peak in late October
* Steelhead – Aug. 1 to Nov. 30 peak in late September, very dependent on water flows, especially in August
* Brown trout – Sept. 1 to Dec. 31, peak in early December
If you’re new to fishing the runs, get properly equipped by reeling in this gear before you go:
* Rod: 8- to 11-feet long, medium to heavy action.
* Reel: medium-sized spinning reel with good drag system.
* Line: 8- to 10-pound monofilament.
* Lure and tackle: Heavy duty ball bearing snap swivels for use with spoons like krocodiles, cleos, castmasters and daredevils will work great off piers and breakwalls.
* For bait fishing: Small hooks in sizes 4 to 6 with slip bobbers, split shot, three-way swivels and bell sinkers for use with spawn, minnows and wax worms.
* Miscellaneous gear: Long-handled landing net for fish up to 20 pounds, heavy duty stringer, needle nose pliers, extra spools of line, garbage bags, and warm clothes (weather conditions can change quickly on Lake Michigan).
Anglers 16 years old or older fishing Lake Michigan and its tributaries need a fishing license and Great Lakes Trout and Salmon stamp, or a two-day Sports Fishing License to fish for trout and salmon in the tributaries (up to the first dam or lake).
Check the “2009-2010 Guide to Wisconsin Hook and Line Fishing Regulations” for fishing regulations. Anglers should note that from Sept. 15 to the first Saturday of the following May, there is no hook and line fishing from one-half hour after sunset to one-half hour before sunrise in the tributaries.\

Salmon Fishing isn't really my thing, but I wanted to make you aware of the options.

Changes Ahead
Hey Gang, there are changes in the works and I wanted you to have some lead time on them.
First, and most importantly, the weekly fishing reports which have been posted on the baitshop blog will be moving to this site this fall. I'll probably start double posting them here as well. I'll keep posting the reports, but as of October 1st or so, you'll need to come here to get them.
Second, I'm in the process of putting together some content for another fishing related blog run by fishing pro Doug Cavin. We're still working out the kinks (well I am anyway) and there will be more news on this in September.
Finally, fall fishing is just around the corner. Judging by the weather, I assume that that might be a short corner. If you are looking to hit the water for some action this fall, I will have availabilities, but as I'll be working on my dissertation, I suggest that you contact me sooner to make sure you can have the days you want.

Shannon's First Fish.
Here's my son Shannon with the first fish he caught all by himself. Over the years I have helped many people catch lots of fish. I have guided people to trophy bass, musky and walleyes. I helped my dad to catch the biggest northern pike of his life. Personally I've caught a bass over 10lbs, a 48 inch musky and a 30 inch walleye, but watching him hook and reel in this potato chip sized bluegill was among the proudest moments of my life.

Two baits for right now
Two Baits for Right Now.
As summer winds up, I usually find myself relying on two baits to produce fish. Our lakes have a plentiful baitfish supply by this point of the year, and I see no reason not to play along. With the crawfish molt over, gamefish will once again turn their attention towards baitfish. As the photocycle gets shorter, this change in attention gets more pronounced.
Therefore I recommend two lures that you should always have at the ready this time of year. Both are easy to use and will catch a variety of fish. The first is a lipless crankbait. There are tons of these baits on the market, and most crankbait manufacturers have a model available. Personally I like to stay traditional, and like the Bill Lewis (Rattle-trap) or the Rapala version (rattlin-rapala).
A lipless crankbait is an easy bait to fish. Cast it out and reel it back in. Its tight wiggle and small size easily imitate the baitfish that most predators are chasing. As for color, I like to keep it simple. On cloudy days I’ll throw a bluegill or shad colored bait, but if its sunny, I like to go for lots of flash and will rely on a chrome or gold. Casting lipless crankbaits along the outside edges of weed-beds is an amazing way to catch a variety of fish. I’ve caught bass, walleye, northern pike, muskie and even channel catfish with nothing more than a cast and retrieve approach. One tip, when reeling in the bait, try to keep your pole at a 90 degree angle to the bait, it’ll be easier to detect strikes and follow through with a hook set. Tip #2: if you’re reeling the bait, and you feel it stop, set the hook. If it’s a fish, you’ll have them, if it’s a weed, changes are you’ll get a bite when you rip the bait free.
The other bait I recommend is a spinnerbait. Again I like to keep it simple, and tend to stay with white or white and chartreuse. Although they are very effective, I prefer not to use willow leaf blades, preferring instead to go with a Colorado or Oklahoma blade. On cloudy days I’ll use a bait with a painted or silver blade, but on sunny days I go gold. I don’t use a trailer hook very often, but I usually use a twister tail grub to add some bulk to the bait.
The approach is simple, throw it out and reel it back in. Look for clumps of weeds, and make multiple casts along the edges or over the top of submerged weeds and hang on. Pike strikes of spinner baits can be vicious. Bass and Muskie will also chase them down.
Keep it simple. Cast these baits out near weed edges, and reel them back in. I’m not promising that you’ll catch a giant, but you’ll certainly have a chance to catch some quality fish.

Maybe its not catch and release but that they're getting smarter.......
Nine-spined stickleback share the human ability to copy each other's behaviour if it's to their advantage.
They're small in size but big in mind: sticklebacks display a remarkably human-like intelligence when it comes to searching for food, according to scientists in the UK. By comparing their own experiences with the behaviour of their fellow fish, the sticklebacks are able to improve their success rate.
The discovery of this sophisticated type of social learning in sticklebacks, known as a "hill-climbing" strategy, suggests that such cognitive tricks might be more common among non-human animals than previously thought.
The study also shows that big brains like humans' might not be the only way to produce a cumulative culture within a species.
"Small fish may have small brains but they still have some surprising cognitive abilities," said Jeremy Kendal from Durham University's anthropology department. "Hill-climbing strategies are widely seen in human society whereby advances in technology are down to people choosing the best technique through social learning and improving on it, resulting in cumulative culture. But our results suggest brain size isn't everything when it comes to the capacity for social learning."
Kevin Laland of St Andrews University, who also took part in the study, said: "Nine-spined sticklebacks may be the geniuses of the fish world. It's remarkable that a form of learning found to be optimal in humans is exactly what these fish do."
In the experiment, reported in tomorrow's issue of the journal Behavioral Ecology, scientists caught 270 nine-spined sticklebacks from the Melton Brook in Leicestershire. The fish were placed in a tank with two feeders, one of which supplied a lot more food than the other, known as the "rich feeder".
The fish that learned to prefer the rich feeder were then allowed to watch their fellow fish feeding in a separate test but, this time, the two feeders had been swapped. After watching for a while, the observers were allowed to choose a feeder for themselves and around 75% were able to work out from their observations that the feeders had been switched.
Lots of animals learn from their more experienced peers to gain skills such as hunting, foraging or evading predators.
"But it is not always a recipe for success to simply copy someone," said Kendal. "Animals are often better off being selective about when and who they copy. These fish are obviously not at all closely related to humans, yet they have this human ability to only copy when the pay-off is better than their own. You might expect this ability in animals who are closely related to humans. In the case of the nine-spined stickleback, they have most likely adapted to their local ecology."

In the experiment, reported in tomorrow's issue of the journal Behavioral Ecology, scientists caught 270 nine-spined sticklebacks from the Melton Brook in Leicestershire. The fish were placed in a tank with two feeders, one of which supplied a lot more food than the other, known as the "rich feeder".
The fish that learned to prefer the rich feeder were then allowed to watch their fellow fish feeding in a separate test but, this time, the two feeders had been swapped. After watching for a while, the observers were allowed to choose a feeder for themselves and around 75% were able to work out from their observations that the feeders had been switched.
Lots of animals learn from their more experienced peers to gain skills such as hunting, foraging or evading predators.
"But it is not always a recipe for success to simply copy someone," said Kendal. "Animals are often better off being selective about when and who they copy. These fish are obviously not at all closely related to humans, yet they have this human ability to only copy when the pay-off is better than their own. You might expect this ability in animals who are closely related to humans. In the case of the nine-spined stickleback, they have most likely adapted to their local ecology."

Sounds Like a Good Problem
Largemouth bass overpopulating many lakes
By Associated Press, Posted: Jun. 13, 2009
Spooner - Wisconsin wildlife officials say bass catch-and-release might be working too well.
The Department of Natural Resources says a mail survey of bass anglers found they kept only 550,000, or 6%, of the 10 million bass they caught in 2006. In contrast, state anglers kept about 2.2 million of 7 million walleye caught, or about 30%.
DNR fisheries biologist Larry Damman in Spooner says high minimum size limits coupled with catch-and-release has resulted in many lakes with overabundant, stunted bass populations in which few largemouths ever reach legal size.
Fisheries managers want anglers to harvest more bass in northern Wisconsin, especially in Polk and Washburn counties, to keep population numbers in balance and improve growth rates.
