Algae Blooms of Summer

By Spider Rybaak

Algae blooms don't stop fish from biting

Two of the state’s most productive lakes, Oneida and Neahtahwanta, are nestled in Oswego County. Their above average fisheries are attributable, in large part, to their shallowness, which allows the sun to warm them quicker, and reach bottom over a larger area than in neighboring bodies of water.

But all those wonderful factors breed a funky side, too: algae blooms.

Found in all stagnant and slow moving waters, algae are an essential part of the environment. Comprising one of the bottom links of the food chain, they’re the main dish of zooplankton, minnows, and tiny insects, which feed bigger fish, which ultimately feed man.

Come summer, however, high temperatures and intense light conspire with the carpet of nutrients on the lake’s floor to create ideal conditions for algae growth. What’s more, insecticides entering the water on run-off contribute to the devil’s brew by killing off vast numbers of the tiny animals that graze on the rootless vegetation. Next thing you know, there’s an algae explosion.

Like everything else that goes up, their numbers must come down; and always do in a spectacular die-off. Fortunately for Oneida Lake, it has a river running through it. When the bloom crashes, it’s quickly dispersed and swept downstream.

Lake Neatahwanta isn’t so lucky. Although it’s fed by a small stream and some underwater springs, evaporation draws off much of what flows in and there isn’t enough power left in the water to break up, let alone disperse, the thick film undulating on the surface like old split-pea soup with rancid pork. At this point, there are only two routes the dead algae can follow: decompose in place and sink to the bottom, or pile up on shore in jagged, blue-green cakes resembling dried river mud in a psychedelic nightmare.

According to Washington State’s Department of Ecology, pets and wild animals have reportedly died after intense exposure to algae blooms. And while people have been known to suffer bouts of stomach pain, diarrhea, and vomiting after swimming or water skiing in the stuff; and folks with a history of intense exposure--like drinking the water--have even come down with nerve and liver damage, there has never been a confirmed death of a human from algae bloom exposure.

So, while the lake smells and looks dead, it’s anything but. Terrestrial beasts and water fowl tend to avoid the liquid miasma because it can make them sick. But the fish don’t seem to mind a bit. In fact, the coating seems to provide shade from the sun, beckoning the fish close to shore.

Just about every lake angler with a few years of experience under his belt has come into contact with blue green algae. Many have even waded in it without any adverse effects.

However, public health officials worry blue-green algae can make you sick and suggest avoiding contact with it.  If some gets on you, they suggest you wash the area thoroughly with soap and water.

Use common sense - don’t drink water with scum floating on it, or any untreated surface water, for that matter. Be especially wary of water that looks like it has a blue-green paint slick on it, or looks like and has the consistency of split pea soup, and smells really nasty.

Off the Wall Panfish

By Spider Rybaak

Oswego, the first port city on the Great Lakes, has three breakwaters protecting its harbor. Replaced and updated over the years, most recently in the 1930s, these concrete structures have been pounded for four generations by the elements. The outer west breakwater, the longest of the barriers, bears the brunt of the abuse.  Its decaying concrete, punctuated by huge holes punched through it by waves and ice, stands in silent testimony to how violent Lake Ontario can get when the wind hits her the wrong way. The only one of the breakwaters accessible to foot traffic, it stretches for roughly 2,000 yards, from the steam station (the two massive smokestacks on the city’s west side) all the way to the lighthouse, a fabulous structure listed on the National Register of Historic Places.

The city of Oswego owns the lighthouse and the Coast Guard operates it. And while the authorities would rather folks stayed off the structure leading out to it, a motley crew of individuals ranging from sightseers and lighthouse buffs to extreme joggers and anglers use the wall as an adventurous route to recreational satisfaction.

There’s really nothing preventing folks from venturing out on the breakwater. Signs posted on the path at the corner of the parking lot at the end of 6th Avenue warn of the hazards slippery and windy conditions pose. But you’re allowed to decide whether you want to risk going out there or not.

From autumn through spring, that’s a no brainer: conditions are generally so extreme, frigid whitecaps slam into the wall. If you’re walking on top of it you’ll probably get hypothermia in less than 100 yards, or, even worse, washed into the drink. And if you think you can beat the wind by walking the apron skirting the bottom of the barrier’s south edge, think again; even on mildly windy days Lake “O’s” waves grow high enough to wash over the top, soaking anyone down below.

Come summer, however, warm temperatures and a wealth of panfish translate into a fishing adventure gung-ho anglers can‘t resist. Most are creatures of comfort and never venture more than a couple hundred feet beyond the breakwater’s source.

They don’t have to.  “Lake perch entering the harbor from the west follow the wall,” says Oswego’s Rob Copeland. And this invariably brings them, likeminded lake smallmouths, even an occasional salmon, brown or steelhead right into the corner where the steam plant and breakwater meet.

“Schools of lake perch are unpredictable,” advises Copeland, suggesting when you hit them just right, you can catch fish till the cows come home. “But when they ain’t around, there just ain’t any around.”

Rock bass can always be counted on to come to the rescue, however. Spring sees massive quantities of the critters averaging about a pound swarm into the Oswego River. Indeed, the fishing is so magical in May, it’s become the stuff of legend.

 After spawning, most head back out for open water. Enough find the habitats in the relatively shallow shipping channel stretching from Wrights Landing to the powerhouse to their liking and take up permanent residence. “There’s so many,” claims Copeland, if you find them, you’ll catch one with every cast.”

One of the most productive spots is the small section of wall jutting due north from the western edge of the powerhouse, just before it banks to the right. Worms, minnows, crayfish and small lures all produce a lot of the feisty googleyes.

But even this close to shore, there’s always the chance a rogue wave can roar over the wall and sweep you into the drink. It’s a good idea to wear a flotation device whenever you’re recreating anywhere near the breakwaters…especially if you venture out a ways. Be safe, fish longer!

If you don’t mind struggling with brush, the shipping channel’s south bank, directly below Breitbeck Park is immune to unexpected wave action and offers the best northern pike and largemouth bass fishing in the city of Oswego. The channel hasn’t been dredged since tankers stopped delivering fuel oil to the steam station some 50 years ago, and a massive weed bed develops each summer. These alpha predators grow big on the cornucopia thriving in the thick vegetation.

The bass take spinnerbaits, YUM Dingers, wide-bodied crankbaits and swimbaits. The northerns respond to all the above except the stickworms, and also like buzzbaits and bucktail jigs. Dark colors like green pumpkin work best when the water’s murky; bright colors work best when it’s clear.
