FEW Lehigh dam capacity question for those who may know

So the Army Corps position is that we will not let pool height exceed 1370 right? If they held more water back, then there would be more water for fishing AND rafting, and there wouldn't be as many fights over the white water surges. So, what does it take to get storage higher? Can the dam structurally take more storage? Is it at a federal/state law capacity limit? 26 miles of public water in a state park, before you even hit further south. What a renewable resource.

LehighRegular and his organization, The Lehigh Coldawater Fishery Alliance have been advocating for years to increase storage capability and have multiple discharge outflows to save the coldest water for the summer.

This is not something that will happen overnight, and is something I feel most of us will not see in our lifetime,

Actually, the dam has the capability for far more water storage, and also different release levels from the dam.

Increasing the level behind the dam could greatly increase the cold water storage, and allow controlled cold water releases when needed most.

Convincing the A.C.E. to do this is the problem - they are all about flood control and white water releases, with fishing friendly releases being the lowest priority.

The LCFA, LRSA, and others are working hard to change this mindset, and there's already been an improvement. It can surely get better, and the more the A.C.E. hears from concerned fishermen, the better.

Yeah, I know that fisherman and rafting companies and ACE have been at each other for quite some time. I am wondering if anyone knows where a structural engineering report is for the capacity limit of pool height 1370. I am just wondering how much water that dam can safely store. I mean, it looks like an enormous structure, but I have no idea what an earthen, boulder monstrosity like that can safely hold back.

I think the Corps gets paid for some level of water retention right? Anyway, I am primarily concerned with where the 1370 number comes from. It just seems to me that if that number goes up higher, then rafters and fisherman will be working with a concerted effort for more storage as opposed to who gets the water and when it comes out.

This fisheries friendly flow in May and April does not seem like a large concession to me by the rafting companies. Who is going to run customers down that river when the water is 40 degrees. I am sure some kayakers would run it with wet/dry suits, but the bulk of business comes from the weekend family excursion.

Well, I just found a map that is HIGHLY interesting> http://www.nap.usace.army.mil/Portals ... solution%20-%205%20MB.jpg

On this map there are projected boundaries that go up to 1392, and it takes surface acreage to 744 from 504 at 1370 pool elevation and it even includes a potential new boat launch area.

Does anyone know where that public comment page is that is filled with tons of white water comments and like 5 fishing comments , I want to write a comment for whatever it is worth.

BeastBrown. Lots of good stuff you are asking. I can answer some of it.

Pie in the sky - the lake level would be held at 1,392' or even 1,400' and the tower modified to a selective withdrawal. This would provide cool water all the way down to Glen Onoko. <68F. However, this is going to take time and a lot of money, however you never know. And there is a study underway to verify this.

Now, where did the 1370' come from you ask? In the FEW Operating Manual there is a stipulation of a 15% seasonal encroachment into the flood storage zone for recreational activities. So that is where we are. However, in drought storage operation, the DRBc can request the Corps go to 1,392' for low flow augmentation. So they do feel comfortable holding the lake above the 15% threshold.

That public comment page has not been updated in years. I know the LCFA has submitted quite a few comments and so have fisherman, but not all of them make it on to the site.

The fisherman and the rafters are not so much at odds anymore. Since the corps has added more water to the lake in the summertime due to the road being moved back in 2004 I think the animosity has subsided between the two groups. We both want mroe water. However, we each have a preference in how it is released.

That said, I feel the Lehigh is a better fishery now than in a very long time!. For some reason I've been seeing more wild looking older fish (plus 2 y/o fish) and plus one fish and so have other anglers that I know fish it, than in past years. Who knows why this is the case. Maybe it is just the increase in summer flows - due to the low flow augmentation. I don't know, but something seems to have changed. And I am talking about water 40 miles from the dam. I also feel that there is quite bit of potential with the lower Lehigh (below the Po) if there could be some very doable release management changes with how Beltzville is run. I believe the LCFA is going to be looking into this.

I fished this past Friday eve. - 40 miles from the dam - on the Lehigh, on the longest day of the year. It was pretty impressive fishing. Olives/Sulphurs and more rising fish than anyone could ask for. A few are posted below. We had the river to ourselves. I am sure if you were anywhere on the river in the low light hours it lit up. I just don't get the lack of use it receives. Well, I do sorta. Oh well, maybe I should not knock a good thing.

Ah, I see, I think I remember hearing this before. Now, that 15% encroachment is for downstream recreational activity, or in the dam, or both. I recall hearing now that there was a hesitation as well to hold water back because of the FEW dam warm water species opportunities with boat and shore access, and perhaps even flooding spawning grounds.

I remember seeing that dam backed up like a lake all the way to small bridge that crosses bear creek up high on the road that turns right at bear creek lake where the spill dam is. I was younger then and didn't know to look to see what the pool height was at that time, but it looked enormous.

I have seen 25" fish pictures in the fall ABOVE White Haven. It is generally hotter there, than say, below Mud and Hickory, due to canopy and springs, but some of these are 100% wild fish that are making it multiple years. Now, after last years drought/heat wave, I have not been down in the Gorge that much. I can say that the wild browns are still surviving in decent numbers, BUT I have not caught a brown over 20" yet this year.

On average, the Lehigh trout do have trouble cracking 20" , in my opinion, because they go into survival mode more quickly in hot water and start to emaciate for the two hot months.

Perhaps most interesting, to me, at least, are the rainbows that are expert nymphers with micro sized caddis. I have seen them cough up tremendous amounts of caddis when landing them. I have caught them on all manner of flies, but they seem to love to scrape those giant boulders for small caddis.

Anything you hear about protecting the warm water species spawn in the lake is a guise for maintaining the limited coldwater pool. If you don't fluctuate the water in the spring ( and how convenient that you protect the nests of the warmwaters at the same time) you can sustain the coldwater that much longer.

2006 late June, Early July was the highest the impoundment has ever been. FEW went to 85% of capacity. 22K coming into the reservoir at the peak, and 200cfs being released for the entire duration of the event! Off the top of my head I think it went to about 1,441'? 8' below uncontrolled spill. But still 15% of storage left. Blue Marsh went to uncontrolled spill mode.

Sounds to me like how the water outflow is managed on the Yough. I still think the rafting industry holds far more sway in water releases for their needs more so than producing a better fishery. At ruffly 38 bucks a head floating down river, who can blame them (USACE & the outfitters).

Yeah, I think that might be when I saw it, right after that event, it was quite an enormous mass of water, lol, you could have taken a power boat right to that first bridge that crosses White Haven Road I think it is by Bear Creek Lake.

I am looking to fish the Lehigh for the fisrt time this Thursday afternoon/evening. Can someone suggest a good section for wading ? Will I need to worry about water temps ?

I will post a report over the weekend.

Wharfrat... The lower river (below Jim Thorpe) will likely warm up this week. The Lehigh Gorge area or directly below the FEW Dam (tailwater - dam to Sandy Run) should remain cool enough.

The water temps coming out of FEW right now are around 63-64F.

ACE, manages the FEW for flood control sothey only let the dam get to 1370 before dumping water to preserve capacity. After that there really isn't any provision for fishing management even though they wrecked a good brook trout fishery to build the dam.
ACE does manage for rafting and kayaking, and there's very limited good fishing in the summer because allthe cold water is released by summer's high temperatures.
Could it be better managed? YES, absolutely, but ACE won't do unless they are bombarded by letters asking for a change in management, or the PFBC asks as much. It's our water not theirs. we have the power to write letters, let's do it!
