SAN TIMOTEO CREEK REACH 4 GENERAL ASSESSMENT - January 6, 1994
Wanda Smith and Allan Bacon
The purpose of the assessment was to establish whether San Timoteo Reach 4 was flowing or dry. We determined that at the least, the lower half of Reach 4 was flowing. All stops are referenced on the attached map.
STOP 1: Hwy. 60 @ dead end street(street intersecting Jack Rabbit Trail). Pictures taken of an unnamed tributary to San Timoteo Creek. Suspected that this is the tributary which the City of i Beaumont discharges its effluent to. 1
Water flowing under Hwy. 60 bridge; has an odor and appearance of effluent. Water is also slightly murky and musty. cfs '2 3 - 4?
STOP 2: Photo(s) of Noble Creek @ 14th St. in Beaumont. I
STOP 3: Photo(s) of probable confluence of Noble, Little San Gorgonio, and San Timoteo Creeks. There was only a dry wash with coastal scrub and cottonwood trees.
STOP 4: San Timoteo Creek photo(s)
Traveled west on San Tim. Canyon Rd., RXR crossing on south side. Crossed railroad tracks @ RXR crossing sign off San Timoteo Canyon Road.
Definite flow in San Timoteo Creek. Flow is clear, probably combined flow consisting of irrigation flows (at this location, an agricultural field is located directly north of the creek) and effluent discharged from Beaumont. Fair amount of riparian vegetation located along the corridor, including several trees and an invasion of arundo. cfs 1 3 - 4
STOP 5: Intersection of San Timoteo Canyon Road bridge and San Tim Creek.
River clear, less cfs flow - maybe 2. Perhaps best spot to establish Reach 4's flow as it is readily accessible and very open. A fair amount of riparian growth, as well as an invasion of arundo, was noted.
STOP 6 : 30260/30240 San Timoteo Canyon Road (private road access) . San Tim Creek flows across a private road at this location. The flow was clear and even greater than at the upstream locations. In addition, a larger .area of riparian habitat is supported by the flows.
Stop 6 was the last stop in which we were relatively certain we were still located in Reach 4. Upon continuing to travel westbound on San Timoteo Canyon Road, we intersected Redlspds Blvd.
MEMORANDUM
Date: November 1, 1994
From: Allan Bacon
To : Keith Pearson, Planning Files
Subject: San Timoteo Creek Sampling on August 26, 1994
Purpose- -
San Timoteo Creek was sampled on August 26, 1994 as part of the Planning sections Ambient sampling. In addition our Permitting Section recently recomended 401 certification for the Army Corps of Engineers for lining the creek, so current water quality data was desired. The sampling was performed by Brad Nelson of the Land Disposal Section, Wanda Smith and Allan Bacon of the Planning Section.
A total of three locations were sampled. The locations were chosen based on their representativeness and proximity to the proposed lining project. Two samples (ST-1 and ST-2) were in the section proposed for lining. The third location (ST-3) is upstream of the proposed lining. In addition the third location had been previously sampled. In all locations nutrients, standard minerals, and bacteria were analyzed for, and at ST-2 a 608 series (pesticides) was run.
Sampling Locations
ST-1 San Timoteo Creek At Waterman Ave.
This location was just upstream of San Timoteo Creek's confluence with the Santa Ana River. The creek bed in this area is maintained by San Bernardino County Flood Control, and is posted with a No Trespassing sign. The'bed of the creek was covered with thick green vegetation. The sides of the creek are sloped and the flood control district has used several constructed attempts to keep erosion and other slope changes to a minimum, including chain link fencing, aluminum sheeting and loss rock riprap.
Sampling results show violations of four basin plan objectives. Sodium was measured at 65 mg/l exceeding the 60 mg/l objective. Sulfate was measured at 73 mg/l exceeding the 45 mg/l objective. Total dissolved solids (TDS) was measured at 397 mg/l exceeding the 290 mg/l objective. Hardness was measured at 200 mg/l exceeding the 175 mg/l objective.
ST-2 San Timoteo Creek at San Timoteo Canyon Road.
This location was different from ST-1 in that the riparian growth did not cover the width of the channel, rather, flow was very.10~ and the riparian area was located adjacent to the water. The flow in this portion originated from a pipe that connects a side area to the main channel. There was no water in the main channel upstream of the discharge. The divided area may be San Timoteo Creek during summer or it may be an area that captures agricultural runoff from the area.
In this location the creek inputs was suspected to be agricultural runoff so a 608 series (pesticides) was taken, however, all constituents results were non detect. Overall water in this portion did not look like agricultural runoff. Total nitrogen was only 1.5 mg/l and total phosphorous was only 0.09
mg/l
At this location only one parameter exceeded basin plan objectives. Sulfate was measured at 50 mg/l exceeding the 45 mg/l basin plan objective.
I ST-3 San Timoteo Creek at Allessandro Rd.
This location is the most upstream location that we sampled. It is upstream of the Army Corps of Engineers plan to begin lining San Timoteo Creek. This area is very natural compared to the other locations. There was a large amount of riparian plants as well as several old cottonwood trees. Historically, the San Bernardino County Flood Control has cleared the creek bed for flood control up to this point (that is why lining is planned up to this area). Minerals were monitored at this location in 1985.
This location had the worst water quality of the three locations. Fecal coliform was measured at 1600 mpn/100ml violating the REC 1 objective. Chloride was measured at 78 mg/l exceeding the basin plan objective of 60 mg/l. Fluoride was measured at 1 mg/l exceeding the .8 mg/l basin plan objective. Sodium was measured at 121 mg/l exceeding the 60 mg/l basin plan objective. Sulfate was measured at 83 mg/l exceeding the 45 mg/l basin plan objective. TDS was measured at 619 mg/l exceeding the 290 mg/l basin plan objective. Hardness was measured at 280 mg/l exceeding the 175 mg/l basin plan objective.
In addition to violating several basin plan objectives, overall water quality has been severely degraded since the 1985 monitoring. Orthophosphate increased from .04 mg/l to.72 mg/l. Chloride increased form 22 mg/l to 78 mg/l. Sulfate increased from 47 mg/l to 83 mg/l. TDS increased from 259 mg/l to 619 mg/l. Electrical Conductivity increased from 472 uS/cm to 939 u~/cm.
Conclusions
While the result show improvement of water quality as it travels down the creek, the fact is that at each of the three locations the water was from a different source. At each location there is substantial habitat, and the proposed lining of the creek would eliminate it permanently.
