Length of Floods

You are interested in studying the influence of the timing and length of small scale flood events on an ecosystem. To do this you need to determine when floods occurred and how long they lasted based on stream gauge data.

Download the stream guage data for USGS stream gauge site 02236000 on the St. Johns River in Florida. Find the continuous pieces of the time-series where the stream level is above the flood threshold of 2.26 feet and store the information on the start date and length of each flood in a data frame.
