The present invention is a gutter system comprising at least a gutter section and one or more downspout sections. It may further incorporate one or more elbow sections. Each of the gutter, downspout and elbow sections may incorporate at least one see-through section. Such see-through sections allow for the monitoring of the rainwater flow and debris in the gutter system. This monitoring facilitates detection of the exact spot of where debris collects in the gutter system, so that blockages in the gutter system can be predicted and prevented, debris build-up in the gutter system can be cleaned, and the gutter system can be repaired. Rainwater runoff can flow through the gutter system, and unnecessary cleaning of the gutter system, and the cost thereof, can be avoided. The elbow sections may incorporate an access port for access to the interior of the elbow, to permit the removal of debris therefrom.
