Carpenter Lake Data Summary
Carpenter Lake is located southwest of Big Lake up Point Mackenzie Road. Carpenter Lake has
been monitored by the Matanuska-Susitna Borough Volunteer
Lake Monitoring program for four years.
This data is the result of the efforts of volunteers and staff of the
Matanuska-Susitna Borough Volunteer Lake Monitoring
Program, which has the goal of monitoring our lakes to obtain
baseline data and to evaluate trends over time.
Details of the monitoring program can be found in the Borough
Lake Monitoring Manual, Standard Operating Procedures 2008
document available online or by request. Current information
can be found on the Matanuska-Susitna Borough Planning
Division’s website at:

Secchi Depth
Secchi depth is an indicator of the clarity of the water. In Matanuska-Susitna area lakes, this reading
is usually a good indicator of algae levels when lakes are not clouded with sediment of large levels of
tannins.
pH
Our lakes usually fall within a range of 6.5-8.5. State standards for pH for “recreation with contact”
state that waters should not be below a pH of 6.5 and not above a pH of 8.5. For growth and
propagation of fish, shellfish, and other aquatic life and wildlife, the pH should stay between 6.5 and
8.5 and not vary more than 0.5 pH units from the natural conditions.
Conductivity (Specific Conductance)
Conductivity is a measure of the water’s ability to conduct an electric current. Conductivity is usually
stable over the sampling
