Predicting what the fishing is going to be like on the Great Lakes from one year to the next is like predicting the daily lottery number - darn near impossible. There are too many variables involved. Weather is probably the biggest factor, and we all know how unpredictable weather can be. Fish plants and their success have a big bearing on what the hot ports are going to be. A particularly large stocking effort or one that was very successful can make fishing better than usual in any given location.

Even something as simple as which way the wind blows can determine where the fish are. Strong east winds push warm water offshore during the spring and makes for poor fishing on Lake Michigan. Likewise, east winds on Lake Huron rile waters, and rough seas make it impossible to get on the water. The same wind during the summer might produce great fishing.

Weather, fish plants and other variables aside, there are still Great Lakes ports that seem to produce decent fishing year after year. Some ports might be hotter than others, but you can count on bending a rod at these ports this season.

The infinite set of variables that anglers and fisheries biologists have to deal with are having a profound effect on the Lake Huron fishery. "We still have lots of cormorants, walleye numbers are high and alewife numbers are low," said Johnson. All of these variables impact trout and salmon numbers.

The downturn in the fishery has been particularly evident with Lake Huron brown trout. (Read more about the Lake Huron brown trout plight in the April 2004 edition of Michigan Sportsman). Fisheries managers have struggled for years trying to find a cure for Lake Huron's slumping brown trout numbers. Moving brown trout plants to Rogers City away from cormorant rookeries and hungry Thunder Bay walleyes is the latest solution. One bright spot is the brown trout's newfound affinity for round gobies.

Chinook salmon present a new set of variables for fisheries biologists. "Alewife numbers in Lake Huron are declining sharply and we are finding that there are a lot of chinooks being reproduced naturally," declared Johnson. Johnson said the super-cold winter of 2002-2003 hurt alewife numbers. "The combination of lots of predators and the hard winter was bad for alewives. It's hard to grow big salmon without big alewives."

Lake Huron anglers had no problem catching chinook salmon in 2003, but big fish were scarce. "A 20-pound king was a major fish in Lake Huron during 2003," said Johnson. "Catch rates were very good, but the fish were small. The lack of large alewives is really beginning to take its toll. Last year, the average adult king on Lake Huron was 10 or 12 pounds." Johnson said that both Lake Michigan and Lake Huron are getting dangerously close to the edge with regard to the delicate balance of predator and prey.

One thing that has thrown a monkey wrench into Lake Huron fisheries managers' plans is the huge number of naturally reproduced salmon that are now showing up in the catch. "In 2003, 20 percent of the chinooks harvested in Lake Huron were hatchery-produced fish," claimed Johnson. "Last time we checked, 15 percent of the chinook catch was natural fish."

Johnson said that Lake Huron is seeing a big influx of naturally reproduced salmon smolts from Canadian tributaries. Johnson said that Michigan has some 53 miles of Lake Huron tributaries while Canada has some 1,857 miles. He said that in a system like the Au Sable River that 97 percent of the returning chinooks are hatchery fish because the river gets too warm for good natural reproduction. But Ontario has a multitude cold, clear streams - like the Garden, Echo, Blind, Mississigi - that are major producers of chinook salmon smolts, and the number is increasing.

Johnson even theorizes that the process of natural selection may be at work and these naturally reproduced fish are adapting to their environment, utilizing the smaller baitfish and outcompeting the hatchery equivalents. Johnson said that the naturally reproducing chinooks are becoming so dominant that they are impacting the pink salmon numbers on Lake Huron and its tributaries. "Pink salmon numbers have been waning on Lake Huron," said Johnson. "The streams are just being dominated by the chinooks."

Coho salmon are becoming more common catches in Lake Huron. "Coho numbers are improving," said Johnson. "We had the best coho fishing in years. They seem to be more predominant in the southern part of the lake - Harbor Beach, Port Sanilac, Lexington - during May and into June.

Lake trout numbers continue to improve on Lake Huron, but the lack of large forage has also hurt lake trout. "Fishing was very good for lake trout off The Thumb last year," said Johnson. "The fish were smaller, but they are surviving longer due to lamprey controls. This year should be very good for lake trout. The fish are leaner too because of their diet."

Deaton said that the fishing usually begins in the southern part of the lake as the salmon disperse out of the St. Clair River. "When we first start fishing we may have to move south toward Port Huron or Lexington," said Deaton. "But as the lake warms, the fish gradually move north. Usually by early May we have good fishing right out of Harbor Beach."

Early-season fishing out of Harbor Beach is a shallow-water affair that boats big and small can take advantage of. "We're usually fishing shallow water from 7 to 8 feet out to 15 feet in May," said Deaton. A spread of body baits, like Long-A Bomber or Yo-Zuri Crystal Minnows in blue/silver or black/silver patterns combined with small spoons accounts for mixed-bag catches of kings, browns and the occasional coho. The baits are run off in-line boards, flatlines and divers.

As summer arrives the salmon move deeper, and Deaton said that Harbor Beach anglers head north and out to concentrate their efforts around the wrecks and near the excellent structure found around Lighthouse Park to the north. Chinooks and lake trout can be found in 100 feet of water nearly the entire summer. With deep water surprisingly close to shore, anglers in smaller boats can take advantage of the fabulous fishery on the right day. Dodgers or flashers and squid or fly combinations and spoons are the hot ticket during the summer months.

Trollers usually enjoy great fishing out of Port Austin by May 1. The lake trout season opens then and anglers will find great sport in 30 to 40 feet of water all the way from Alaska and Eagle bays to Grindstone City and Lighthouse Park. Anglers routinely take limits of suspended trout then that will average 6 to 8 pounds. Mixed with the lakers is a hodgepodge of chinooks, brown trout and cohos. The fishing is easy because everything is acclimated toward the surface and anglers don't have to contend with the rocky substrate that the area is known for.

The focus switches to salmon when the kings begins showing up in quantity by mid-May. Last year, the kings were on the small side, averaging only 4 to 8 pounds, but bigger fish are common. Action focuses around the Port Austin light some 10 or 11 miles northwest of the harbor in 40 to 80 feet of water. Here, warming water and current concentrate baitfish and hungry kings. In-line boards with body baits, spoons and crankbaits, and shallow-set 'riggers and divers, produce limit of spring salmonids. By mid-June, savvy skippers point their rigs to the northeast to search out the 200-foot depths and spot downriggers and lead-core rigs near the thermocline 50 to 70 feet down. They are usually rewarded with a box full of kings and the occasional steelhead.

Even though the bulk of the fishery focuses on late-summer salmon, fishing can be good in May and June for a smorgasbord of brown trout, lakers and spring kings. Hot action can be found near Seagull Point just to the south of Rogers City. Body baits and in-line planer boards are standard fare. Lake trout can be taken with regularity all summer long with dodgers and flies or cowbells mated to P-Nuts or Spin-n-Glows. Trollers need to keep a watchful eye out for trap nets that a deployed in the area.

Rogers City has a state-of-the-art launch facility located within the municipal harbor. For more information on charters, accommodations and lodging, contact the Roger City Chamber of Commerce at (989) 734-2535 or online at www.rogerscity.com.
