Clean Water Act Anniversary


In celebration of the 31st anniversary of the Federal Clean Water Act’s passage on October 18, 1972, several activities will take place in October  throughout Lodi involving a cooperative effort by the City of Lodi, Public Works Department, City of Lodi Parks and Recreation’s Lodi Lake Nature Area Docents, local school groups, and several employees from  Washington Mutual Bank.


1.                October 17, 2003- 3:30 P.M. – Storm Water Lift-Station Clean- Out – Vinewood Park, Tokay and Mills Ave., Lodi -  Lodi High’s Environmental Club, will for the

second year, host a student event where trash cleaned out from the storm water lift-station, will be sorted, counted and classified.  This “non-point” source of water pollution enters the stormwater system and is discharged into the WID canal, which eventually flows to the delta.  The public is invited to attend.


2.  October 18, 2003- Lodi’s Salmon Festival- Lodi Lake Park- 11 A.M.- 8 P.M.- The  City of Lodi Parks and Recreation Department is sponsoring a family focused day at the north side of Lodi Lake Park.  Local agencies will be on hand with information tables, live salmon tanks, and professional staff to help the public understand its natural resources along the Mokelumne River watershed. Children’s carnival like activities and an evening salmon BBQ is also planned.

The City of Lodi’s Public Works Department will be sponsoring the Mokelumne River Watershed Mural Project, a mural in progress being painted by Liberty High School students.  The multi-panels will eventually reside in the Lodi Lake Nature Area as an interpretive tool.  A watershed model will also be demonstrated by students detailing the potential pollution problems in the watershed. 

Grant Plath is the contact person for this project. He can be reached at: 333.6890.  


3.     October 27, 2003 CLEAN-A-CURB DAY - On Monday October 27, 2003, from 8:00am-9:30pm, students from Heritage Elementary will clean around the school’s surrounding neighborhood sidewalks, curbs, and gutters located on Garfield Street, between Eden and Hilborn. Nine classes, totaling approximately 200 students, grades K-3, will conduct this clean-up day with support from the City of Lodi Public Works, the Police Department Partners,  9 employees from Washington Mutual Bank, and Lodi Lake Docents. CLEAN-A-CURB DAY is part of the City of Lodi’s efforts to prevent pollution to the Mokelumne River.  Door hangers, colored by the students, will be distributed to residences in the neighborhood.  These door hangers feature a large Chinook salmon, native to the Mokelumne River, on one side, and storm water prevention tips, in Spanish and English, on the other side.  A CALFED grant has paid for the printing of this material.


The message Heritage students are trying to send to the public is what runs off the curb and into the stormdrain flows directly to the river, and not to a wastewater treatment plant, as does household and industrial sewage.  


CLEAN-A-CURB DAY has become popular with this school site for several reasons.  October 27th is the site’s track change day, the one day per year when all student tracks must be in school for the day. Heritage is an over-crowded school site and classroom space does not exist for all registered students. CLEAN-A-CURB DAY is a creative solution for the teachers and students that need to stay out of overcrowded classrooms. Promoting a public service, such as raising public awareness about stormwater pollution, also teaches the students the importance of their role in the local natural environment’s health. Many of these children have never been to the Mokelumne River. 


Since students will be working near open streets, extra safety precautions have been addressed for those who will drive through the area. Partners, the Lodi Police Department volunteer group, will assist along with the Community Service Office and the community service bank employees, in protecting the students from traffic in the area.


At the completion of the morning clean-up, students will then be bused to the Lodi Lake Nature Area, where docents will lead students on a tour of the Nature Area, alongside of the Mokelumne River, where their neighborhood stormwater eventually travels.  Stewardship of the river is promoted by the docent program’s focus.  “A clean, healthy river begins with clean streets at home”, is the message sent home with the visitors.  Washington Mutual Bank employees will remain with the students through the morning’s visit to the Nature Area.



4.                Lodi’s Storm Drain Detectives (SDD) - Will participate in the World Water Monitoring Day- Oct. 18 - The recent Oct. 10, 2003, SDD monitoring data of the Mokelumne River will be added to the data base being collected by the world wide efforts to help local communities learn more about water quality issues.  Visit their web-site’s for more information:  www.worldwatermonitoringday.org, or www.lodi.gov, see Storm Drain Detectives.


5.       Lodi’s Storm Drain Detectives- Water Toxicity Workshop -  For the 4th consecutive

year, the SDD’s will host Stephen Clark, Environmental Toxicologist, in a water toxicology workshop, after school at Tokay HS, on Oct. 27, 38, and 30, from 3- 5 P.M.  This workshop uses a rigorous protocol to test various ambient waters from around Lodi.  The 48-hr. incubation of Ceriodaphnia dubia, a water flea, in local water samples should determine if the water is toxic to the same aquatic life typically found in our rivers and lakes.  This program is funded by a CALFED grant.
