Sparrowbush is south of Hawks nest on the NY side. Very large put in and take out area.
As you continue north on 97 up and over Hawks nest, you will start to come down from the top of that famous area. (It will look familiar...numerous car commercials shot on that short windy mountain road overlooking the river) As you come down the hill you will cross a bridge which is over the Mongaup River.
You can pull off there on the N. bound side and but in at the bridge. A little cumbersome for a pontoon but no problem for a kayak. You can float down the monagaup about 200 yds into the Main Delaware River. Its pretty steep and the water is full of boulders so if you choose this, be careful. If you continue on 97 after the mongaup River about 1/4 mile, there is a big pull off on the ------- edited in(I MEANT LEFT SIDE)and I believe its some sort of DEC area. you can park there (lots of parking spots) and follow the trail to the rivers banks, about 50 yds.
A few suggestions.
1) the float form the Mongaup is about 3-5 miles. Can be tricky going around the islands so make sure its not too dark as you are approaching Sparrowbush
2) If you do this float, fish the area where the Mongaup dumps in. Its fast pocket water in a nice riff area. Usually holds a lot of smallmouth. Nothing huge but Ive had days where Ive taken a dozen or more fish in less than an hour. Just below the mouth of the mongaup, there is a big wide pool which holds BIG stripers. If its cloudy or late afternoon, do not hesitate throwwing a big surface popper.
3) South of there you will hit another long pool which fishes real well for stripers and Ive even seen some walleye as well. Anywhere along that float should yield you a more smallies than you know what to do with.
4) beware of rafting brigades
5) if you fish to when the sun goes down, make sure you have a badmitton racked and a head net. I was stuck near the mongaup in fish one evening 2 years ago, about this time of year when the sun went down, I had the craziest hatch of Dobson flies you can possibly imagine. Thousands of them. If you have never seen a dobson fly, you will certainly know what they are quickly if you are in that area late. If you have seen them, you know how they are. They seem to fly right at you and continue to try and "attack you". Think about thousands. It was not pleasant rowing out that entire stretch.
