Dredging and Vegetation Removal Completed

The stream has been dredged and non-native vegetation has been removed. A swath ranging from 10 feet wide to 40+ feet wide has been cleared on either side of the stream bed. This photo is looking downstream from a spot between the 5th bridge and the south lake. The next step is a detailed survey to establish the exact elevation of the stream channel at approximately 35 locations between the north and south lakes. This is a critical step as the flow of the stream depends on the elevation falling between the two lakes. Before this project began, the north lake was only 1 foot higher than the south lake. That meant that the stream only had 1 foot of fall over its entire half-mile length. This project includes replacing the weir where the stream comes out of the north lake. The new weir will raise the elevation of the north lake by approximately 1 foot, effectively doubling the amount of fall as the stream flows to the south lake.
