a map was not really needed, but a face with the name sometimes helps.
Sharon conglomerate settles in 3 distinct places in Ohio. And all 3 places have limestone, sand and conglomerate. This layer is 10-50 feet thick and is compressed causing water to rise , thus spring fed. The sandy bottoms and stream banks you notice along these streams is caused from deterioration of the limestone. Giving it a quick clearing even after a heavy rain. The 3 areas for this are Southwest Ohio, Northeast Ohio and Southeast Ohio. But as mentioned we are only on the fringe.
So i give these points and information that I have gathered from studies and reading over a long period of time that have helped me figure out why we are not trout rich. We do have cold streams, just not of any size . Just the these few we will mention. I am only writing this to help others find what I have found. If that makes any sense at all. So i apologize if a lot of what I write is in laments terms.
HOW TO IDENTIFY A COLD WATER STREAM VISUALLY.............................
A typical cold stream , or spring creek will have a mossy substrate made of several aquatic plant life. Also, look for 2-4 inch cobblestone in the riffles . From their the stream bottom structure will be as mentioned of sand and very clear with a noticeable temperature change. The banks will be stable with sand as well or plants with a bigger root system. We could go on, but most of us know what a C.W.H. is already. But when searching for your own recreation it's good to know what to look for if your interested.
WHAT A TROUT NEEDS OUT OF IT......
The P.H. levels are crucial. Aquatic insects are crucial. Stream banks/erosion are crucial. Which is a problem in Ohio with all the erratic rain and snow we receive. Are biggest problem here in the buckeye state is our silt ridden streams. Which is another strike on the reproduction of our Steelhead. If our precipitation stays at normal levels, and we have a colder than usual spring, we would have a good reproduction rate. Which was the case last late spring. Evidence of this is has been recognized by the Cleveland metroparks. And was written with visual pictures on Mike Dirkelac's ROCKY RIVER FISHING REPORT with the metroparks.
- The SQM score to be excellent needs to be at least 22 points.
- 37*-64* degrees is desired for spawning .
- Water flowing at spawning gravel areas are (supposed) to be at velocities of 1/2-3 feet a second.
-Aquatic biology in stream must be abundant.
THE MAD RIVER
The Mad River is Ohio's oldest state runned Trout fishery. It is picturesque, and cold until it reaches the northern suburbs of Dayton. The river it's self runs 66 miles. The headwaters of this river are cold as well and you can view them on a biology report from the EPA. Almost all of these headwaters contain Browns and some do have Brooke as well. The ODNR stocks this river annually with 6-8 inch browns. The good people of Trout unlimited , the mad men chapter do a fantastic job keeping this river up to par. And for any information you can contact Mad River Outfitters.
