Delaware River Report: June 30, 2025
The release from Cannonsville is 600 cfs and the spill has stopped. The heat and sun are back for today. Nymphing and swinging wets will be the best bets early. We should see some sulphurs, cahills, and Isonychias today. Hopefully we’ll see some activity in the afternoon but the sun could push them into the evening. Look for the coldest water for the best shot at dry fly fishing. The Beaverkill, Lower East Branch, and Beaverkill all peaked in the high 60’s to low 70’s yesterday. The water temps will go higher today so it’s time to give those rivers and fish a break.
Today will be 86 degrees with a mix of clouds and sun. Wind will be 5 – 10 mph from the South.

Delaware River Report: June 29, 2025
The release from Cannonsville is 600 cfs and the spill has stopped. This should help keep the West Branch water temps in check. All of the river temps look okay this morning. The West Branch is still at decent levels for floating and wading. Today looks like a good fishing day with some clouds and little wind. Nymphing or swinging wets should be the best bets early. Blind casting Isonychias or cahills before the hatch could payoff too. We should see Cahills, Sulphurs, Isonychias, and some olives in the late afternoon / evening. Possibly earlier with the cold water on the upper river sections.
Today will be 80 degrees with partly cloudy skies. Wind will be 5 – 10 mph from the North.

Delaware River Report: June 28, 2025
Cannonsville is spilling 65 cfs. The release from Cannonsville is 801 cfs. The rivers cooled down a bit and everything looks good this morning. The West Branch is at decent levels for floating and wading. We should keep the clouds all day. Nymphs and wet flies should be the best tickets early. Streamers have been good in low light and could be good if we get the afternoon thunderstorms. Cahills, Isonychias, and sulphurs have been around in varying numbers on different river sections. The hatches should push a little earlier on the coldest river sections.
Today will be 82 degrees with cloudy skies in the morning and possible isolated thunderstorms in the afternoon. Total rainfall should be .05″. Wind will be 10 – 15 mph from the South.

Delaware River Report: June 27, 2025
Cannonsville is spilling 65 cfs. The release from Cannonsville is 801 cfs. The flows are still slowly dropping throughout the system and wading is an option on the West Branch and Upper East Branch. The cooler weather and clouds have helped the water temps but please check them with a thermometer before fishing the Beaverkill, Willowoemoc, Lower East Branch and the Mainstem today. The cloud cover has been a welcome change after the bright sun this past week. Nymphing or swinging wets will be the best bets early. The intensity of the hatches has been variable but patience should pay off. We should see sulphurs, cahills, and Isonychias in the late afternoon / evening. Streamers are still a good bet in low light times.
Today will be 69 degrees with cloudy skies. Wind will be 10 – 15 mph from the South.

Cannonsville is spilling 186 cfs. The release from Cannonsville is 801 cfs. The heat is past and today looks like a good day to be on the water. Wunderground is calling for .09″ of rain this afternoon. If we keep the clouds and light rain, but not enough rain to increase the spill, we’re set up for some good fishing conditions over the next few days. The West Branch temp at Stilesville dropped and is 55 degrees this morning. The weather and cooler temps could push the hatches up and we may see bugs earlier in the day. Sulphurs, cahills and Isonychias are still making up the majority of the hatches. Streamers have worked well when the sun hasn’t been beating down on the water. The lower East, Beaverkill, Wiilowemoc, and Maonstem temps are all peaking too high to fish. It’s time to give these rivers a break until they cool back down.
Today will be 77 degrees clouds and a few rain showers in the afternoon. Total rainfall should be .09″. Wind will be 5 – 10 mph from the South.

Cannonsville is spilling 410 cfs. The release from Cannonsville is 1,003 cfs. It’s been a tough couple of days in the heat and bright sun. The water temp at Stilesville is dropping as the spill decreases. The west Branch and Upper East Branch have held on well during the heat wave. The Lower East, Beaverkill, Willowemoc, and Mainstem have all been too hot to fish. It looks like the heat wave ends tomorrow and we may see some rain again. We’re still seeing some sulphurs, cahills, and Isonychias. The change in weather over the next three to four days should push the bugs back to normal.
Today will be 89 degrees with a few clouds. Wind will be 5 – 10 mph from the North.

Cannonsville is spilling 730 cfs. The release from Cannonsville is 1,103 cfs. The increased release should help drop the water temps. The West, East, and Mainstem are still high but slowly dropping and clearing. The Beaverkill and Willowemoc both peaked over 70 degrees yesterday so please check water temps. They may cook today over there. Today is going to be another bright, hot day so plan accordingly. Nymphing and streamers early and hopefully a mix of Sulphurs, Cahills, and Isonychias in the evening.
Today will be 95 degrees sunny to partly cloudy. Wind will be 5 – 10 mph from the North.

Delaware River Report: June 23, 2025
Cannonsville is spilling 753 cfs. The release from Cannonsville is 600 cfs. Y rain hit us hard and the rivers are off color. The feeder streams are dropping so we should see the main river flows drop and clear a bit today. Wading is not an option today but the Beaverkill is 956 cfs and should drop enough to offer some options this week. The West Branch is fine for floating.

The release from Cannonsville is 600 cfs. Today looks like a warm one with best chance of rain coming overnight. The river fished well with nymphs yesterday mid day and by afternoon most people were finding dry fly shots. Sulphurs, Cahills, and Isonychias were making up the bulk of the bugs but there were some olives and a few caddis mixed in. Today’s weather may push the bugs a bit later in the day. It’s going to be warm with no wind so have your spinners ready towards dark.

The release from Cannonsville is 801 cfs. The spill has ended on both reservoirs. The runoff is subsiding and all the rivers are in good shape this morning. We’re at good levels for wading and floating. The sun may push the hatches back a little again so some light rain and cloud cover would be welcome. Sulphurs, cahills, and Isonychias are making up most of the hatches. Blind casting Isonychias or cahills could payoff too.
Today will be 77 degrees and partly cloudy. There is a slight chance of a rain shower. Wind will be 10 – 20 mph from the North.

The release from Cannonsville is 801 cfs. The spill has ended on both reservoirs. Some areas got hit with storms yesterday. the West Branch came through just fine and it in good shape for both wading and floating. The Beaverkill is up quite a bit so the lower East is also. Some Mainstem feeder streams were also high and off color yesterday afternoon. The colder water temps have helped the fishing pushing the bugs earlier in the afternoon. The bugs and fishing have been really good in the cold water sections since the spill stopped. Sulphurs, cahills, and Isonychias are making up the bulk of the hatch.
Today will be 82 degrees with a mix of clouds and sun. Total rainfall during the day will be .17″. We may see a few storms pass though. Wind will be 10 – 15 mph from the South.
