Spring Description
Dykes Spring forms a roughly circular pool that was about 80 feet indiameter on date of visit in March 2004.  Water flows from a largelimestone fissure that is about 8 feet wide and 40-50 feet long. There is a large (6-8 feet in diameter) boil on the surface at the backend of the fissure, which was als o wider tha n the rest of the fissure androunded.  The depth of the fissure was not measured but appeared tobe at least 20 feet.  Several types of fish were observed in the pool, r angin g in size from less than an inch to 15 inches long.  Water inthe pool was clear and pale/milky blue.  The bottom was mostly sandyexcept at the edges of the limestone fissure, and there were algae on thebottom and on the submerged trees.  Movement in the spring pool raisedclouds of silt.

There is a backwater swamp/wetland area behind the spring; it flowsinto the top of the spring basin in times of high water.  The springcreates a serpentine run that is 20-30 feet wide and 75 yards long. The depth in the run was 5-6 feet on date of visit in early March 2004,but only about 3 feet 3 weeks later (there had been no measureable rainin the interim).  There is heavy algae growth in the spring, in vividgreen mats and strings/filaments.  The clear water of the spring andits run present a contrast to the darker water in the river.  Banksrose up from the spring from 3-10 feet in an area of hardwood bottomlandforest.  Dried algae on the banks extending 3-5 feet above the springsuggested that the water had recently been much higher.

A sign at the spring says camping is not allowed.  There is arope swing at the pool.  A dirt road looped by the spring from theeast.

Personal Impressions
Dykes is a very attractive spring, although the algae growth is likelymuch greater in the summer.  It was a great place to cool off andhave a swim.
JF was so irked by the large tree that had fallen into the spring thathe spent 15 minutes lugging/lurching it out of the spring fissure. The tree was about 35 feet long.  He knows he should not have donethis (one should let nature take its course), but could not restrain himself.
