Wheaton Branch is separated by this spillway from stormwater control pond located just below Dennis Avenue. Since the upstream portion separated by this facility is not large, the significance may not be serious. However, no fish can go upstream from here.

Soapy, dark, gray water comes from Wheaton Branch. Clear water comes from main stream.

--

Darker water is coming from left side stream (Wheaton Branch). It is suspected that the stormwater control pond located upstream from this site contributes this dark water. The pond functions as a dam and makes water stagnant. Once water becomes stagnant, organic matter in the water tend to decay. Consequently, water becomes turbid.
