Delaware River Report / Conditions June 11, 2011

Rain! Hallelujah! We had rain overnight, and it has continued to be cloudy and rainy this morning, which has yielded better river temperatures downstream towards the main stem, while having very little effect on the flows. The forecast calls for clouds all day – perfect for mid-day hatching. The dortheas and cornutas came off strong in the morning yesterday, with the typical 30 min at dark. With perfect olive weather we expect to see those same cornutas throughout the day today.
