Delaware River Report / Conditions June 22, 2021
Some of the storms did hit us last night. The rain came down pretty hard before dark but the most of it soaked into the ground. The West Branch looks fine this morning and the flow hasn’t increased. There is a slight bump in flow on the Beaverkill and East Branch. We woke up to a little more rain falling but that should clear up by the afternoon. The air temp will stay in the 60’s and wind will be 10 – 15 from the North.
The Lower East Branch, Mainstem, and Beaverkill at Cooks Falls all peaked over 70 degrees yesterday and are starting of hot today. It’s time to give those rivers a break and fish cold water areas.

Delaware River Report / Conditions June 21, 2021
The thunderstorms never materialized yesterday afternoon so the river flows are starting off about the same as yesterday. we’ll be a bit warmer today in the high 80’s but that should bring a better chance of storms today. It looks like we may get just under 1/4″ if they don’t track south of us. Wind will be 10 – 15 from the South. The best dry fly action was as the sun dropped but people did catch fish mid day in the sun too. Sulphurs, olives, cahills, and some isonychias will cover the mayflies. We cool back down into the 60’s tomorrow. The 10 day forecast shows some decent rain towards the weekend.
The Lower East Branch, Mainstem, and Beaverkill at Cooks Falls all peaked over or just under 70 degrees yesterday. It’s time to give those rivers a break and fish cold water areas.

Delaware River Report / Conditions June 20, 2021
We had some rain in the evening but it soaked into the ground and the river flows are basically where they were yesterday morning. Today will be mostly cl0udy with a high of 81 degrees. Wind will be 5 – 10 mph from the South. According to Wunderground there is a 30% chance of some thunderstorms developing in the afternoon. Most of those tend to slide South of us so we’ll see. The forecasted rainfall is negligible. We are still mainly fishing sulphurs, olives, and cahills but the isonychias seem to be picking up. Blind casting in the riffles worked yesterday.
The Lower East Branch, Mainstem, and Beaverkill at Cooks Falls all peaked over or just under 70 degrees yesterday. They are starting off warmer today and will peak higher due to the sunshine. It’s time to give those rivers a break and fish cold water areas.

Delaware River Report / Conditions June 19, 2021
We had just enough rain overnight to knock the dust down on the dirt roads but no enough to bump the river flows. The clouds stuck around most of the afternoon and some decent fish were landed. Sulphurs and cahills seemed to land most of the fish with a few on olives. Today we’ll have a bit more sun with a slight chance of an afternoon thunderstorm. The air temp will hit 84 degrees with wind 5 – 10 mph from the West. Nymphing, swinging wets, and blind casting isonychias and cahills in the riffles are all good bets. The sulphurs have been coming in the evening but may shift earlier if we get an afternoon thunderstorm.

We’re coming off another cool night. The air temp should climb to 80 degrees with a mix of clouds and sun this afternoon. Wind will be from the South 5 – 10 mph. Any rainfall should be negligible. Yesterday seemed to fish like a more normal sunny day with some sporadic action early and decent activity once the sun dropped. Nymph and swing wets to fill in the gaps. Some people are finding fish early on spinners and olives before the sun hits the water.

Delaware River Report / Conditions June 17, 2021
We had quite a few reports of good sulphur hatches during the wind and sun mid afternoon yesterday. That was much earlier than expected. The wind made it tough but fish were landed. There was a smaller mix if cahills and sulphurs as the sun dropped in the evening. The dark blue sedges came out towards dark as usual. We’re coming off a cold night and most of the river temps are started off a couple of degrees colder than yesterday. We’ll hit the low 70’s today with sunshine and wind 5 – 10 mph from the North.

We didn’t get enough rain yesterday to bump any of the river flows but we did keep the cloud cover most of the day. More rain probably would have pushed the hatching earlier but fish were landed. We’re coming off a cool night so the water temps dropped throughout the system. That’s definitely a bonus. today should be sunny, 69 degrees, with wind 10 – 15 mph from the North. The overnight air temp should drop to 45 degrees. Cahills, isos, sulphurs, tan caddis, and dark blue sedges should cover most of what you’ll see.

Delaware River Report / Conditions June 15, 2021
Most of the thunderstorms forecasted for yesterday afternoon slid South of us as usual. The Beaverkill and West Branch above Walton have slight bumps in flows this morning. There was some action during the rain and some cahills after but a lot of the sulphurs came towards evening. Wunderground is calling for a high of 67, cloud cover with a some rain, wind form the north 10 – 15 mph. The rainfall should be negligible at .13″. Wunderground hasn’t exactly been nailing the forecast lately but hopefully we see the clouds. There has been some activity in the mornings. If we do get a little rain the bugs may come early. If it passes us and the sun sticks around nymphing will be your best bet until evening. The dark blue sedges in #14 have been coming out in good numbers at dark too.

Delaware River Report / Conditions June 14, 2021
We had a heavy mist here on the lower West Branch yesterday but most of the rain seems to have missed us. The cloud cover and little rain we received did help the bugs and people found fish eating earlier in the day. Blue wing olives, sulphurs, and cahills were the most talked about flies. The sun came out in the afternoon (not part of Wunderground’s forecast) and pushed things back to evening. Everything is dry this morning so the overnight thunderstorms missed us too. The Beaverkill did get a little rain that bumped the flow but it has already dropped back. If Wunderground is correct today we have a 50% chance of rain totaling just under 1/4″. A mix of clouds and sun, 75 degrees, and wind 5 – 10 from the South.
It won’t take much sunshine to heat up the Mainstem, Lower East Branch, and Beaverkill so it’s time to check the water temps with a thermometer before you fish those rivers.

We have good cloud cover this morning. It sounds like our best chance of rain is now in the afternoon. It looks like .09″ total. The air temp will be in the high 70’s and wind will be 5 – 10 mph from the South. There is a chance of some thunderstorms in the afternoon and overnight. We’ve had a lot of sun lately so today’s cloud cover could make for an interesting day. Hopefully the sulphurs and cahills come earlier in the afternoon. It’s definitely a good day to have your blue wing olives handy. Psilotreta caddis are everywhere in the evenings.

We’re starting off this morning cool with good cloud cover and a chance of a shower. The sun may break through in the afternoon but anything is better than the full bright sun we’ve been dealing with a lot this June. The air temp will hit 74 degrees with light winds. Overall it sounds like a good day to be on the water. The bugs have been late on the sunny days so hopefully the cloud cover and potential light rain pushes them early today. If no blind casting cahills in the riffles has worked wel for some people. Otherwise nymphing or swinging wets is your best bet until the sulphur and cahills start hatching.
The lower East Branch, lower Beaverkill, and Mainstem will be too hot to fish today. The water temps peaked over 70 degrees yesterday. Please give these rivers a break and fish the cold water areas.

It’s going to be cooler today with the air temp reaching 76 degrees. Mostly sunshine with wind 5 – 10 from the south. Yesterday sounded like a mixed bag with some people finding fish early and others not until the sulphurs came as the sun dropped. The dark blue sedges offered some fishing during the day but a lot of them came in the evening too. Blind casting cahills and big charcoal caddis patterns in the riffles could be a good option during the day. Otherwise nymphing during the day with sulphur action in the evening.
